[Erppcatoolkit-support] EP Toolkit 2.84 released

[Joseph D. <jd...@ma...>]

EP Toolkit version 2.84 has been released:
https://sourceforge.net/projects/erppcatoolkit/ <https://sourceforge.net/projects/erppcatoolkit/>

Thanks in part to the kind support of two researchers, this release includes enhanced support for multiple-session data and tracking of standard deviation information.  I’ve also spent a lot of effort on the plumbing, making it faster and more efficient.  I also went through the entire tutorial to ensure all the steps are still working and fixed a lot of bugs and glitches.  Finally, I got tired of the continual problems from Matlab’s incomplete support for the many variations (especially unicode) of .txt files, as when editing .ced or ANOVA files, so I wrote a function that should prevent any further issues.

1) In the Edit function, clicking a Select checkbox also changes the weight. 

 2) Fixed crash when updating the EPwork cache. 

 3) Added support for multiple sessions with the same subject. 

 4) Added option in SampleTest to compare between different sessions. 

 5) Fixed crash in ANOVA function when performing pairwise followups on significant effects with more than two between group levels. 

 5) Fixed crash in Window function when leaving the pane, changing the cellnames in the chosen dataset, and then returning to the Window pane. 

 6) Fixed crash in Cells subpane of Edit function when changing name of a trial of single-trial data to a novel name in the Trial subpane and then switching to the Cells subpane. 

 7) Enabled reading of text files with a greater range of variations in character encoding, end-of-line markers, and field separation markers, including Unicode16. Also accommodating .csv suffix. 

 8) Now allowing NaN in EEG channels. I imagine it'll break some things but better than treating them as zeros I think. 

 9) Now ignores bad channels during rereferencing and marks as a bad trial/average if all the reference channes are bad. 

 10) Noise estimates are now always a simple mean regardless of the averaging method chosen. Also, grand average noise is now the subject-wise mean of noise estimates from the first level of averaging. 

11) Cousineau-Morey confidence intervals now based on number of waves from the same subject being used in the figures. Original implementation was not correct. 

 12) Fixed outputting an extra column of NaNs in the cell mean tables for ANOVAs with no within factors. 

 13) Added ability to keep track of correct standard deviation scores after rereferencing or adding data together with Edit. 

 14) Added ability to window standard deviation scores. 

 15) Added option to keep track of trialwise standard deviations, which is quite computationally and memory demanding so by default it is turned off. 

 16) May now drop noise information to reduce memory and time requirements. 

17) When importing data, fixed implicit mastoid channel a mirror of the wrong channel for case where it is mean mastoid reference with one explicit and one implicit channel and the order of the channels has bee changed by the CED file. 

18) subjectwise standard deviation and confidence intervals are now computed on the fly so no longer need to store them, saving time and memory. 

 19) Added support for session information and session ANOVA factors and ICC reliability output. 

 20) Fixed crash in ANOVA when between group level names have more than one character. 

 21) Fixed waveforms not being displayed in expanded channels when chosen colors are non-consecutive (e.g., just blue and green). 

 22) Fixed crash in View Topos when sampling rate of voltage data is not an even multiple of 1000 (e.g., 512). 

 23) When loading E-Prime spec files, stopped assigning EPoffset to .onsetdelay field as the delay is likely present in the stimulus appearance time as well. 

 24) Fixed crash when applying Transform to a file with channel adds, as in preprocessed data. 

 25) Fixed crash in View Waves when displaying data with ERPimages. 

 26) Fixed crash in Preprocessing function with fMRIb fMRI correction option and there are TR markers with decimal sample numbers. 

 27) Fixed losing all events with decimal samples when using Trim function. 

 28) Fixed crash in View Scan when there are no events in the present waveform. 

29) Fixed crash in View Scan when zooming in or out. 

 30) Fixed View Scan not showing single event lines at the correct latency. 

 31) Fixed View Scan not displaying event line if the initial epoch did not have an event or leaving it unchanged if changing from an epoch with an event to one without. 

 32) Fixed crash when using low-pass filter with sampleTest. 

 33) Fixed labels of scale graph for View Waves. 

 34) Fixed combined factors from PCA output too large (not divided by number of factors going into waveform). 

 35) Fixed generation of names of between group adds from the ANOVA function. 

 36) Fixed crash when running CSD in Transform.
