What's New in Streamline-ENV?

Version 2.5.0 (03/03/2010) Greatly enhanced Certificate of Calibration Summary Report helps users identify problems. Now includes complete multipoint data sets, information and charts. pH slope is automatically computed and included in the Certificate of Calibration report. When the pH slope falls outside specified limits it is visually distinguished using a red font. Many calibration constants and parameters (DO charge) are monitored and those falling outside acceptable limits are printed in red font in the Calibration Report. Calibration errors and warnings are now included in the Calibration Report. The "uncal" command is now supported during calibrations to reset a sensor's calibration to default values. Streamline opens even larger files in less time. Easily handle files with dozens, or even hundreds, of parameters and millions of samples. Expanded quality assurance processing with new conditional outlier flagging. Set conditions for any parameter and, if the condition is met, flag the entire sample. As an example, if a sonde were exposed to air during an extreme low tide event, then Streamline can locate depth values less than zero and flaf all the parameters in those samples. The median value is now shown in the tables shown on the QA/QC charts. A new boxplot (interquartile range) algorithm to flag outliers is available in the QA/QC module. Standard Deviation and BoxPlot outlier flagging methods are graphically illustrated on QA charts. Faster on-the-fly refreshing of data and visual editing environment when performing QA/QC corrections. Automatically recognizes and imports CDMO NERR SWMP files in their comma- and tab-delimited text formats. Streamline automatically extracts the station code and other metadata and populates appropriate metadata fields with the information (e.g., station name). The file may contain raw data or processed data in which case the flag data columns are also imported. Examples and descriptions of the format are given in the CDMO NERR SWMP Data Management Manual (version 6.3, February 2010). Files are available in the data download section on the CDMO web site. File imports up to 20 times faster! Set custom, long or descriptive parameter names before a file is imported. Streamline attempts to identify names of known parameters when importing data and can replace the custom name with the known form of the parameter. Precede custom parameter names with a "$%" (excluding quotes) to keep custom names. For example, rewrite "Optical Dissolved Oxygen" as "$%Optical Dissolved Oxygen" before importing the file. The statistical analysis interface has been redesigned to simplify operation and report generation. New minimum-value and maximum-value reports reports have been added to the Statistical Analysis module.. Median and lower and upper quartiles included in statistics reports. Group data and compute statistics for custom time intervals. Data may be grouped by hour, 2 hours, 3 hours, 4 hours, 6 hours or 12 hours. For instance, to examine 6 hour data intervals starting at 12:30am, select a 6 hour interval and set a start time of 30 mintues. Statistics will be computed in intervals from 00:30-6:30, 6:30-12:30, 12:30-18:30, and 18:30-00:30. For files without water level included in the report, Streamline will compute the water depth and if pressure, temperature and conductivity are present. The computed water depth is compensated for changes in density due to chemical composition and atmospheric pressure variations. Added ability for user to control the placement and style of legends on charts in Analyst. The legend may be placed above or below, to the left or right, or inside the graph area on XY charts and on top or bottom for stacked plots. Improved resizing of chart, data and file listing during form resize events. A new symbol style chart template has been added to Analyst. Choose from dozens of date formats and 12 or 24-hour time formats for a chart's x-axis label to customize time-series charts. Add annotations to your charts with a click of the mouse. Annotation may be dragged to any location on the chart. Edit a chart's title, sub-title and axis labels. Fully customizable y-axis scaling on charts. Corrected calibration plotting error. On multipoint calibrations, the wrong parameter was sometimes plotted on the chart when performing the 2nd (or 3rd) calibration point. This has been corrected. User manual has been updated to detail the new features of Streamline-ENV and includes several new examples.

Version 2.2.0 (08/17/2009) Significant rebuild of the Data List spreadsheet in Analyst to improve handling of very large files. Handhelds (models 556 and 650) are reset to main screen after connecting with Streamline to download files. Added scrollbar to the list of parameters (with check boxes) under the 'Series' tab in Analyst. This keeps the lower parameter names and check boxes from disappearing below the visible area when a file contains large numbers of parameters. A new Grey Scale template included for charts. Added command to operate sonde wiper in Deployment Manager during discrete sampling. Improved font resizing when Data List is zoomed in and out. Removed Desktop Folder and shortcut created during program installation. "Auto YSI' option could select incorrect instrument if multiple instruments had been deleted from the database. This error is fixed. Cursor focus returns to the terminal emulator screen after clicking one of the menu options. Catches error (Run-time error '481': Invalid picture) that can occur when a calibration summary is being created. This error is caused by the use of an invalid image file selected in preferences as your company logo. A message will alert you that your logo image file is corrupt. To fix the problem, select a new image file known to be valid. Date listed in statistics reports using the 'Mean Series Format' aligns with the first day of the month for monthly reports and with the first day of the week for weekly reports. Dates are correctly rounded in daily statistics reports saved to Excel (issue appeared under the 'Mean Series Format' when data for a particular day was available only after 12 noon). When using Device Manager to upload files from a sonde or handheld, a message box is displayed if the file already exists that provides the option to overwrite the file or to skip the upload. This gives the user the opportunity to rename or move the existing file to prevent it from being overwritten.

Version 2.0.0 (12/01/2008) Using the File Import feature, you can import and analyze data from other instruments and sources. Data can be imported from Excel Workbooks or delimited text file formats. Streamline will handle long or descriptive parameter names that are assigned to a file before it is imported. For example, rather than a shortened name of "ODO" the complete phrase of "Optical Dissolved Oxygen" can be used! Correct for fouling and calibration drift to recover data accuracy. Streamline implements standardized methods outlined in the USGS document Guidelines and Standard Procedures for Continuous Water-Quality Monitors: Station Operation, Record Computation, and Data Reporting (Techniques and Methods, TM1-D3) to compute data corrections. New options let you save calibration summary reports in Microsoft Excel®, PDF, WORD® RTF formats or even as a web page (html)! Easily plot and analyze DAT files containing more than 20 parameters. New V2 sondes with multiple optical ports can store more parameters in a file than can be plotted at one time in EcoWatch®. Streamline handles these multiparameter files with ease. Enhanced options in the user Preferences allows you to display dates in a variety of US and International formats. You may now change the 'Site Name' that is stored in a file! In Analyst, click on a Site Name in the File Listing and enter the new name. New file management functions - rename or delete files directly from the File Listing! A printer other then the Default printer can be selected when printing the file listing, a chart, or data listing in Analyst. Create and save high resolution chart images by setting a scaling factor. New AUTO feature for YSI devices. Automatically connects and matches it with a sonde in the database or, if the device is not yet in the database, Streamline will add it. Added command button to run the wiper on a sonde in the Deployment Wizard. The option is available when running in Disrcete Mode. Status messages are provided to indicate state of acquisition and recording in the Deployment Wizard when collecting real time data from a YSI sonde or GPS. Enhanced identification of optical sensors in 6-series and V2 sondes with multiple optical ports. An optical sensor can be installed in any bulkhead port (i.e., 'T', 'C', 'O', and 'B' port designation) and Streamline will recognize it. For example a turbidity probe is recognized in the oxygen port (designated 'O' on the sonde bulkhead). Stop discrete and unattended sonde deployments with the 'Cancel Deployments' option in the Deployment Wizard. Sonde is placed in low power (sleep) mode to conserve battery power. Windows and forms are positioned and centered in for easier viewing when first opened. New area style plotting method is available in the graph preferences in Analyst. New chart templates are available including bar graph, bathymetric-area, and several tailored for vertical profile data. When saving statistics reports or exporting data files (to individual Excel® files), the Excel® files no longer include an extra blank worksheet named "Sheet1". Additional help tooltips have been added to the File Listing in Analyst. The names of data files in the File Listing are shown in blue text to indicate that QA/QC operations are applied to one or more parameters. In the drop down parameter list in the File Listing, an asterix next to a parameter name indicates that QA/QC applied to that parameter. The time span for a file is shown in blue text in the File Listing to indicate that time limits are specified that limit the time span. Expanded description of sensor names in the 'Probe Maintenance' of the Calibration Summary Report Details form. Enhanced status messages in Depoyment Wizard's status bar to detail play/record settings. Seconds are displayed when using the cursor tracking features in Analyst. Visible parameters on a chart are maintained when applying data limits (i.e., limiting the time span of a file). Select and copy text directly from the terminal emulator window. Terminal retains focus after a menu selection to maintain key capture. Corrected parameter report bug indentified by King County, Washington (thank you!). The bug had the potential to misidentify a parameter's visibility in the report settings when it was actually turned off. It resulted from a value retained and maintained for backwards compatibility with older model sondes. Only a few parameters were affected and the bug manifested itself only when templates were utilized. File listing correctly sorts by sample count and time span.

Version 1.5.0 (09/20/2007) New file management feature organizes calibration reports and automatically creates shortcut links in Analyst. Reports are sorted by instrument and date to allow the user to quickly acces any report. New expanded User Manual included with Version 1.5. Streamline version 1.5.0 adds a great new feature to the Statistics module recommended by our friends at the RI Department of Environmental Management and the University of Rhode Island.  The new feature adds an additional format for the statistics report that provides the mean (average) of the parameter measurements versus time so you can generate monthly, weekly, daily or hourly reports.  To access the new reports open Analyst and then select 'Statistics' from the drop-down list (Action column in the file listing) for the file you want to analyze.  This opens the Statistics window - in the menu area use the drop-down menu to change from 'Standard Format' to 'Mean-Series Format' and then under the 'Summary' drop-down list select the time interval (daily, hourly, weekly, monthly or summary) over which the averages will be computed. Both the new and the traditional statistics format can now be saved to an Excel file in addition to PDF, HTML or RTF.  Look under the 'Save Report' menu for the new option to save as an Excel file so you can analyze and plot the results using Excel. New QA/QC function uses the operational range of the sensors (as specified by a manufacturer) (e.g., conductivity, temperature) as a QA/QC condition to remove outliers. Streamline-ENV maintains a database containing the sensor range information (minimum and maximum) for the sensors.  Values be modified to update range information when the manufacturer updates the specifications. Improved statistics report formatting for better presentation on various printers. Created file associations for Streamline-ENV data files so that files with 'dat' or 'qaf' may be opened with Streamline-ENV.  Double-click a file in Windows Explorer (or right-click the file and select 'Analyze with Streamline-ENV from the menu) to launch Streamline-ENV and open the file in Analyst. Calibration help files have been entirely revised to have up-to-date instructions and information. New calibration help is included for chlorophyll and ORP probes. Access Shortcuts to specify the source and destination folders in the Batch Export program. Improved accuracy when Calibration Manager attempts to select the parameter shown in the calibration chart. This feature compares the sensor name selected from the calibration menu to the parameter report. Since the names do not always match, a parameter may not be selected or a variant (e.g., conductivity instead of specific conductivity) may be chosen. In such cases the correct parameter may still be selected manually. Width of the columns in the File List (in Analyst) are automatically adjusted to display the widest text string. The thousands separator and use of a comma as a decimal character is supported (Set these values in View Preferences).  Note: When a comma is used for the decimal character, the Data List in Analyst may only be saved to tab-delimited and HTML formats. Added mechanism to correctly handle certain DAT files containing alternate format date and time.

Version 1.3.4 (07/13/2007) User Preferences includes a new option to specify the folder where the YSI Code Updater program is installed.  If you do not have the YSI Code Updater installed you should download the program from www.ysi.com and install it.  This allows the Code Updater program to be run from inside Streamline-ENV. 'Tel' and 'Fax' are printed before their respective numbers in Calibration Summary footer. Fixed Excel Export function accessed by right-clicking the data list in Analyst.  Worksheet protection is also turned off during the export so that the Excel worksheet format and columns may be modified. Changed "Override 'Out of Range' warning" to "Don't allow 'Out of Range' option" to clarify the meaning of the setting in the User Preferences.  If the box is checked then Streamline will not allow a calibration to continue when the sonde returns a 'Warning: Out of Range! Accept Y/N?' message.  When unchecked, the user can select whether to accept the calibration or to cancel the calibration. You can now cancel from 'Save As' dialog boxes in Analyst. Corrected invalid path reference to the YSI Code Updater program ("File Not Found" error).  The path to the code updater folder is now set in VIEW-->PREFERENCES.  Once the directory containing the updater.exe program is correctly specified, a checkmark will appear next to the entry location on the PREFERENCES dialog.

Version 1.3.3 (06/04/2007) Added option to set the chlorophyll temperature coefficient in the Advanced Sensor settings. Advanced Sensor options for Turbidity set correctly for 6026 and 6136 models. Label for Wiper Interval units corrected to display minutes.

Version 1.3.2 (05/19/2007) Calibration History is customized with your organization's logo.  If a logo is not defined, then the default sonde picture is shown. Analyst's File List synchronized with the Deployment Manager.  During a real time (discrete) sonde or GPS run the contents of the File List are updated when a new file is created. Enhancement of Device Manager interface including a wider calibration chart and Help display. Improved toolbar sizing in Device Manager when 'Large Fonts' are enabled in Windows Display properties.

Version 1.3.1 (05/10/2007) Web links corrected in help menu and on 'About' dialog window. File name format for files created in Deployment Wizard modified to include the year, month and day.  The format is FNAMEMMDDYYYYhhmmss.dat where FNAME is the discrete name set by the user (a blank name is acceptable), MM is the month, DD the day, YYYY the year, hh the hour, mm the minute and ss the second. Changed "% Good" heading to "%" in the Statistics Report.  '%' indicates the percent of the data samples that have not been flagged as invalid. Modified menu spacing in the Statistics Report window so the down arrows remain visible when 'Large Fonts' are enabled in Windows Display properties. Clicking the 'Save Report' button (instead of the down arrow) in the Statistics Report window will bring of the "Save As" dialog box with the default PDF format.

Version 1.3.0 (04/06/2007) NOTE - The registration procedure has been modified to simplify the process.  Users that previously registered and received a License Registration Code must request a new license when upgrading to version 1.3.  Click here to register now.  We apologize for any inconvenience and will provide a new license as quickly as possible after receiving your new User Code Number. Calibration Manager attempts to select the parameter shown in the calibration chart.  This feature compares the sensor name selected from the calibration menu to the parameter report.  Since the names do not always match, a parameter may not be selected or a variant (e.g., conductivity instead of specific conductivity) may be chosen.  In such cases the correct parameter may still be selected manually. Data sampling rate is increased by a factor of two during calibrations. Improved calibration report formatting. A new probe maintenance section is included in calibration summary reports to document the replacement of wipers, membranes and o-rings and wiper parking. Sensor name is shown in the header section of the calibration summary report pages. A second, separate comment page is no longer included in the calibration report if no comments are entered. The sensor name is shown in the header section of calibration summary report pages. A new option in the pressure calibration procedure allows the user to select the barometric pressure and have it calculate the depth offset.  This feature applies only to non-vented sondes.  A zero offset should always be entered for vented sondes. Added a new help section in Calibration Manager for turbidity probes. Revised and updated the calibration instructions and guidelines in Calibration Manager. The 'Clean Optics' command in the calibration module functions correctly to start the optical wipers. New tooltips were added to the command buttons on the main screen of Device Manager. Device Manager provides a warning if removable communication ports (e.g., USB to serial converts, PCMCIA serial ports) are no longer available. A new module is available in Device Manager to assist with firmware updates for YSI sondes and handhelds.  Launch the YSI Code Updater program from within Device Manager. Clarified the barometric pressure equation in the calibration help file for dissolved oxygen to identify the units for the Altitude_local variable. Resolved 'Object variable or With block variable not set (Error 91)' error that intermittently appeared following the creation and display of calibration summaries. Improved display of tabular parameter listand values shown during calibrations in Calibration Manager.  The list can be scrolled if the parameter list extends to far down. Corrected indexing when setting temporal data limits for a file and individual parameters. Statistical analysis reports now include 'Percent Good'. Percent Good is the number of measurements for each parameter that have not been flagged compared to the total number of measurements for the specified time period. Water density is calculated and is available in Analyst when a file containing measurements of temperature and salinity is opened. Added option in QA/QC module to subsample a data set.  Subsampled data can contain raw or average values. Increased resolution of GPS data saved by Deployment Wizard. Added capability to switch between small and large font sizes in the terminal emulator. All preferences are correctly saved and reloaded at startup.
