Version 2.5.0

New Features

• SortClient : added new Trodal Peak/Valley Display that can show all the permutations of electrode i vs electrode j for peak or valley heights.
• SortClient : added new option to 'gang' together the gain, threshold, filter, and zoom settings for all electrodes within a trode.

• SortClient : added a new mode to the Activity Display so that it will show only the currently selected channel
• SortClient : added ability to easily associate every Nth spike channel to an analog channel
• SortClient : can now collect sample sets in trodal mode, and waveform selection/inspection works properly
• SortClient : can now set threshold by dragging the horizontal white threshold line in the waveform view, this now also works in trodal mode
• Ref2 : added ability to work with channels in terms of stereotrodes or tetrodes (see ref2-trodal.rtf)

• SortClient : space bar always erases displays, 'x' key pauses, updated the Quick Reference dialog
• SortClient : added mouse-wheel zooming of 3D Cluster Display
• SortClient : added an option that allows right-click context menuing in all views (as opposed to Alt-right-click)

Version 2.4.0

New Features:

• Added new Ref2 client, replaces Ref and Fec
• Added support for Windows XP theme for all programs, minor display tweaks
• SortClient : new Display Pause function to freeze the displays but still acquire data
• SortClient : added toolbar button for Assisted Sort view, added n,p,del keystroke handlers
• The licensing dialog makes it more obvious when multiple keys exist

Improvements:

• SortClient : The Drop Count section of the status bar will flash red if the drop counts are non-zero
• SortClient : can now cancel out of an Add Unit in template sorting mode by hitting Esc
• SortClient : in stereotrode/tetrode mode, display the threshold on the waveform view, and make the dividing lines between the electrodes a brighter color
• SortClient : If you add a new unit from the cluster displays by holding down Ctrl and left-clicking, the display will now flip into viewing the template set.
• SortClient : increased a buffer size to help reduce data drops in some cases
• SortClient : pressing the 'Sort' button to sort the template set now more accurately reflects the sorting that the MAP will do - TCClient : Add ability to alphabetize all Events, which makes the displays easier to decipher
• TCClient : Add ability to not display the error bars on the tuning curve plots.

Bug Fixes:

• SortClient : Fix bug where if you set stereotrode/tetrode mode before pressing Start, the MAP continued to do single-electrode thresholding.
• SortClient : Switching data mode would always turn on waveform limits, but the GUI would still show them as being turned off. This was harmless for recorded data (as waveform limits are turned off when recording starts anyway) but it could be confusing.
• SortClient : Fix bug in the 'Accept All Units in Row' function in Assisted Sort view
• TCClient : Fix possible 'jittery' display problem that only occurred with some video cards

Version 2.3.4

New Features:

New Features:

• PlexNet: Now has explicit control over sending External Events via PlexNet

Improvements:

• Server: Computer-MAP clock discrepancy correction algorithm is now allowed to do more correction

• PlexClient.dll: Minor changes made to accommodate the MEA Workstation

Bug Fixes:

• Server : Fixed strange interaction that caused the timing of keyboard events and start/stop events to get out-of-sync while MATLAB is running on the same machine

Version 2.0.6

New Features:

• Quick reference dialog can now be printed
• Now pulls up the pdf documentation from the Help menu

Version 2.0.3

New Features:

• Ability to open .exp files supplied on the command line
• Added a persisted option for the default preamp gain for analog channels, which now defaults to 1000 (not 500)
• Rearranged the General options panel a bit
• Added new option to automatically stop and re-start runs with new file names after a selected amount of time has elapsed
• Server can now be configured to use serial ports COM3 or COM4 in addition to COM1 and COM2

Bug Fixes:

• Efficiency improvements for activity display
• Fixed bug with the 'Set all rows as the top row' function for Zoom in the Channels grid view
• Fixed bug in Server that could cause redundant copies of external events on XS2 on MXI systems

Version 2.0.2

New Features:

• Changes to support 40-bit timestamps
• Support for multiple DI boards
• Removed several property pages and configuration options for things that never need adjustment in Server; simplified menu structure
• Changed the defaults on several configuration options in Server

Bug Fixes:

• Fix problems in range validation for slow channel gain
• Made UI for slow channel decimation clearer
• Adding a new unit during waveform crossing no longer resets unit assignments for other template set waveforms
• Fix problem where variance lines for remaining units disappeared after deleting the selected unit
• Restrict the pre-threshold values to be between 1 and NPointsWave-1 ticks
• The control panel entries for waveform limits now affect the display limits, not the hardware waveform limits
• The display limits cannot be set larger than the waveform limits
• Persist waveform limits active flag, active and background limit rates to registry
• Fix problem where pulling up context menu would prevent future point selection on 2D Cluster View
• Change Scale to Zoom in Channels panel
• Doing auto-gain would set the Gain Scope to be 'Current Channel', but would not update the Control Grid. It now updates the Control Grid. The 'override waveform limits' option that was already available when doing Auto-Gain and Auto-Threshold collection now also applies to Auto-PCA. This prevents the current channel from finishing its PCA collection much sooner than the other channels.
• Minor UI tweaks (fix chopped-off text, only enable controls when they are relevant, etc)
• Changed text for MinInt(µsec) to Refr ISI in the Control Panel
• Changing channels during auto-XXX collection no longer resets waveform limits if they have been overridden during collection
