OpenSorter Tech Notes

Events read from the tank are missing if there is a gap in the data


Product: OpenSorter, OpenExplorer, OpenDeveloper, OpenBrowser, OpenBridge
Version: All
Date Added: 2012-10-17


In order to save time, the TTank server will stop searching for data that matches the requested criteria if there are no matches in the last 1 million events. If the data is sparse and there is a large gap, the data after the gap might not be extracted.


Note: This solution is only valid in v2.16 and above.

To override the search limiting feature and force the tank to search the entire block for data on each channel, you must manually enter a registry key:

  1. Run the Registry Editor (regedit.exe).



    For 64-bit machines, the registry path is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TDT\TTank

  3. Right-click the right pane, point to New and click DWORD (32-bit) Value on the shortcut menu.

  4. Name the new entry SEARCHLIMIT.

  5. Right-click SEARCHLIMIT and click Modify on the shortcut menu.

  6. Enter a Value data of 1.

  7. Click OK.

  8. The TTank server will now search until the end of the block for events instead of performing a quick search.

To restore default behavior:

  1. Use the Registry Editor to browse to the SEARCHLIMIT DWORD (32-bit) Value you created and delete the entry or set to 0.
3-D feature space plot missing or not updating correctly


Product: OpenController, OpenSorter
Version: All
Date Added: 2010-10-04


When using Windows Vista or Windows 7 machines, the 3-D feature plot in OpenSorter or in OpenController's PCSort window may be missing or may be erroneously highlighting waveforms.


If the feature space plot is missing, turn off "Threaded Optimization" for the affected application(s). This setting can be found in the NVIDIA Control Panel and is set on a per-application basis.

  1. Right-click the desktop and select NVIDIA Control Panel on the shortcut menu.

  2. Within the NVIDIA Control Panel, select Manage 3D settings.

  3. Select the Program Settings tab and find the affected application(s).

    For OpenSorter, add C:\TDT\OpenEx\OpenSorter\OpenSorter.exe.

    For OpenController, add C:\TDT\OpenEx\Controller\OpenController.exe.

  4. Turn the Threaded Optimization setting to Off for the affected applications(s).

  5. Click Apply and close the NVIDIA Control Panel.

  6. Restart the affected application.

In OpenSorter, if previously selected waveforms remain highlighted in the feature space plot even though they are no longer selected, turn off the advanced visual settings for that application.

  1. Navigate to **C:\TDT\OpenEx\OpenSorter**

  2. Right-click OpenSorter.exe and select Properties on the shortcut menu.

  3. Select the Compatibility tab.

  4. Select the checkbox Disable desktop composition.

  5. Restart OpenSorter.


Upgrade to v2.18 or later.

Using the Gigabit interface with 32-Bit versions of Windows Vista or Windows 7


Product: TDT Drivers, OpenEx, OpenDeveloper, OpenExplorer, OpenSorter
Version: 70
Date Added: 2008-08-15


After performing a typical installation of the TDT Drivers, running RPvdsEx results in an error message which states "Error loading component specification file: CmpSpec.txt". Or, if you launch zBUSmon, you will see "NO TDT card Detected."


32-bit versions of Windows Vista or Windows 7 can be used with some adjustments to security settings and program compatibility settings. This procedure has proved successful for running OpenEx with a Gigabit interface.

Configuring 32-bit versions of Windows Vista or Windows 7 for TDT software installation

  1. First, you must be using an Administrator account.

    Turn off the User Account Control (UAC) for the account that will be used to install the applications.

    The option to turn this on or off is seen when viewing the details of your user account.

  2. Download the software installation packages from the web from here: V70 software installation packages Contact TDT to request passwords for applications you have purchased.

  3. Edit the properties of the *.EXE installation files. Under the Compatibility tab, click the Run this program in compatibility mode for: checkbox and choose Windows XP (Service Pack 2) in the dropdown.

  4. Run the install packages as normal. Start with the TDT Drivers and reboot when asked. Install OpenEx before installing OpenDeveloper, OpenExplorer or OpenSorter.

Hardware Installation

Windows will recognize your hardware when it is first installed. When prompted, let windows search for drivers automatically. If you have any further difficulty, contact TDT Support.


Upgrade to Optibit Interface (FO5 with PO5/PO5e/PO5c/UZ3) and the latest version of TDT software. Current drivers are also compatible with the 64-bit USB Interface.

Can't access settings options in OpenSorter


Product: OpenSorter
Version: 1.2 and 2.6
Date Added: 2007-08-21


In the Algorithm Settings lists, drop down menus and browse functions are not available.


Options for some settings can be selected by double-clicking the desired setting box in the list. This cycles through the choices one at a time. Some settings (such as the Derived Properties settings) cannot be selected at all. To work around this problem, manually enter the value(s) of Derived Properties you wish to use. The options for Derived Properties are Vmax, Vmin, MaxSlope, and Area. To use multiple options, separate each with a comma.


This problem has been corrected and is available in releases above 2.6.

OpenSorter crashes or graphic panes are not shown correctly


Product: OpenSorter
Version: 1.0
Date Added: 2007-09-04


OpenSorter may have a problem generating the window pane layout. This can cause the program to crash when using the Select Nearest Trace function.


To resolve this issue, delete the OpenSorter.xml file. This file is in the same folder as the OpenSorter.exe application, typically C:\TDT\OpenEx\OpenSorter.

When OpenSorter is used again, OpenSorter.xml will be recreated.
