Intan RHX release notes ----------------------- * Version 3.0, 11 February 2021 - First release; started with v3.0 to avoid confusion with older Intan software. * Version 3.0.1, 12 February 2021 - Fixed bug that caused crash during electrode impedance measurement. * Version 3.0.2, 24 March 2021 - Improvements to Spike Scope: - Added RMS display, consistent with old software. - Added spike rate display. - Number of spikes in recent spike history can now be as high as 500. - Each channel's recent spike history is persistent when channels are changed. - Added 'Take Snapshot' and 'Clear Snapshot' buttons to permit freezing spike history in background of display on a per-channel basis. - Added longer post-trigger spans to PSTH tool: 5s, 10s, and 20s. - Added ability to use analog inputs as digital triggers in PSTH tool. - Added ability to use analog inputs as digital triggers in Display Trigger (in Trigger tab). - Added ability to display thresholded analog inputs as digital signals in Spectrogram Tool. - In data file playback mode, added 'run immediately' option after 'jump to position'. - Extended range of y-axis spacing between waveforms on waveform display. - Fixed bug where 'Stop' button was not working during rewinding. - Fixed bug where the 'Automatically Save Trigger Channel' option in triggered recording was not working. - Fixed issue where software crashed upon exiting on some Macs. - Fixed crashing upon software startup with some smaller screens. - Improvements to TCP output: - Added ability to disable and enable individual channels for TCP output while system is running. - Improved TCP parser so that path names and file names may include spaces. - Fixed TCP output timestamps to match timestamps in recorded data. - Fixed issue where TCP data output could fill up software 'Waveform FIFO' buffer under certain conditions. - Changed TCP parameter name 'DisplayTriggerAnalogVoltageThresholdVolts' to 'TriggerAnalogVoltageThresholdVolts'. - Switched to latest version (v5.2.3) of Opal Kelly DLL. - Changes to support Linux compilation. - Windows installer: - Fixed issue where certain anti-virus programs would interfere with Windows installation. - Added additonal DLLs to Windows installation: api-ms-win-core-winrt-string-l1-1-0.dll api-ms-win-core-winrt-l1-1-0.dll OpenCL.dll * Version 3.0.3, 15 April 2021 - Added 50 ms option to PSTH pre-trigger and post-trigger spans. - In "One File Per Signal Type" data file format, added option to save auxiliary inputs (e.g., acccelerometer data) in amplifier.dat file. - Fixed bug that sometimes causes crashing when PC audio was enabled. - Fixed bug that did not display auxiliary inputs or supply voltages from second headstage when dual headstage adapter was used. - Expanded OpenCL compatibility to fix problems with OpenCL initialization on some systems. * Version 3.0.4, 5 August 2021 - Fixed small memory leak that occurred when saving in the File Per Signal Type file format. - Improved XML settings file parsing so that files that don't include any headstage channels can still be correctly loaded. - Minor improvement to make error logging more detailed and efficient. - Modify episodic triggered recording algorithm to ignore brief trigger-off events. - Improved optimum SPI delay finding algorithm so that setting delay manually is less likely to be necessary. - In data file playback mode, electrode impedances are now displayed. - Fixed issue with external fast settling in RHD systems not properly triggering as a result of digital input activity * Version 3.0.5, 3 February 2022 - Removed unused Context Help buttons from dialogs. - Reduced latency of spike .dat file writing so that these files are updated as soon as spikes are detected. - Added option to start software without OpenCL. - Improved TCP parsing to handle unexpected whitespace in a string of commands. - Added WriteToDiskLatency setting for users to control. - Added CreateNewDirectory setting for users to control. - Fixed displaying 'save to disk' icon for enabled non-amplifier signals (e.g., aux in, digital in, analog in). - Fixed small memory leak during TCP data streaming. - Altered 'Rescan Ports' behavior so that if the system went from no headstages to at least one detected, the displayed port will update to the present chip(s). - Added drag'n'drop option for various settings files. - Added more descriptive error messages when a Probe Map file is loaded as a general settings file. - Fixed bug that would only flag channels as spike-TCP enabled if they were also waveform-TCP enabled. - Removed unusable 'aux in wideband' checkbox hidden for RHS systems, because they don't have aux in channels. - Added more descriptive error/warning messages when channels loaded from XML file are inconsistent with those currently plugged in. - Fixed bug where loading data for playback that had aux inputs saved in wideband file wouldn't parse correctly. - Fixed bug with external fast settling not properly triggering as a result of digital input activity. * Version 3.0.6, 1 April 2022 - Fixed bug with FilePerChannel digital ins/outs not being indexed correctly. - Increase max number of columns to 16. - Put waveform display in a scroll area so that when too many columns are present to be displayed at once, a scroll bar can be used. * Version 3.1.0, 3 June 2022 - Fixed memory issue that caused systems with multiple RHD2216 chips to erroneously duplicate channels. - Added Plotting Mode options in the Performance menu, including a new High Efficiency mode that plots data more efficiently. - Allowed some elements (including window size, position, and control panel state) of the basic GUI appearance to automatically load/save through QSettings. - Added current channel name to the Window Title of the Spike Scope, ISI, PSTH, and Spectrogram tools. - Added current loaded filename to the Window Title of the Probe Map tool. * Version 3.2.0, 6 March 2023 - Allow user to specify which port(s) to read data from in Advanced dialog - For One File Per Channel file format, when playing back data as it's being written, allow for jumping to the end of data for near-real-time playback - Support for use of XEM7310 board in Intan controllers to replace XEM6010 and XEM6310 - Allow user to specify use of median instead of average for reference calculations - Fix various issues with re-recorded playback data dropping data blocks at the end - Allow user to specify whether or not to use max # of channels possible in synth mode - Add "Get CurrentTimestamp" and "Get CurrentTimeSeconds" TCP commands - Improved error detection and reporting for TCP commands - Various improvements in RHX API including easier use of the API without Qt, and additional utility functions described in Rhythm and RhythmStim documentation. * Version 3.3.0, 23 August 2023 - Improve TCP reception of commands to not duplicate slot connections - Add Chip Test Mode - Fix issue where for RHD chips, Rescan Ports would not run chip calibration - Fix 7310 bit files so that for RHS systems, using a sample rate other than default (30 kHz) will no longer cause the software to use the wrong sample rate. - Fix crashing when attempting to open a new file for recording fails, instead display an error message and stop acquisition.
