[Erppcatoolkit-support] EP Toolkit 2.51 released

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

EP Toolkit version 2.51 has been released:
https://sourceforge.net/projects/erppcatoolkit/ <https://sourceforge.net/projects/erppcatoolkit/>

Notable changes include further improvements to EEGLab and mff file format support, addition of a cross-validation option for PCAs, and improvements and corrections for the robust ANOVA implementation.  Note that the EGI CED files have been modified to adopt a uniform labeling system for the vertex channel.  This may result in incompatibilities with files using the original EG CED files but can be addressed by changing the name of the vertex channel as needed.
1) When none of the CED channel names match the data but there are the same number of EEG channels, it will be assumed that they are the same channels and in the same order.  A warning message is provided.  

2) Fixed crash when mff average file has only one subject.  

3) Fixed crash in Edit function’s cells tab for single subject average files with no trial specs.  

4) Fixed crash when appending an average file with trial specs usiong the Edit function.  

5) Fixed aborting averaging when generating a combined subject average file wherein one of the files after the first has more trial specs than the first average file.  

6) Standardized electrode labeling (e.g., E10) when reading mff average files.  

7) Standardized EGI vertex electrode naming (e.g., E129 rather than Cz or REF or VREF) in EP Toolkit code as well as bundled CED files.  

8) On the assumption that EGI users have largely migrated from GSN200 to Hydrocel nets, the default right mastoid channel has been changed from 101 to 100.  

9) Fixed crash when continuous set file has a single eventHdr event and it has an NaN or numeric .value.  

10) Handles the NaN values that EEGlab seems to set channels to when it automatically edits them to being bad data (in contrast to EEGlab’s manual channel rejection which operates via flags in the reject.manual field).  

11) Fixed crash in Edit function when combining cells or subjects and there are trial specs with numbers.  

12) Cells no longer sorted alphabetically when data files are saved in EGIS format.  

13) Fixed crash when appending to a data file with an empty trialspecs field.  

14) Robust ANOVA routine drops ill-conditioned runs from the bootstrapping computations.  

15) Handles case where the entire bootstrap sample is drawn from the same observation and treats as an F of inf.  

16) Edit function’s Factors subpane now provides both negative and positive peak chans.  

17) Fixed crash in Edit function when changing order of cells.  

18) Fixed crash when reading in EEGlab .study datasets.  

19) Fixed crash when merging files (as when using single file mode or reading EEGlab study datasets) that do not have subject specs.  

20) Fixed crash when windowing with the "measure then collapse" option.  

21) Corrected erroneous error message that degrees of freedom of robust ANOVA is calculated per multivariate rather than univariate approach.  

22) Added cross-validation option to PCA.  

23) Fixed NaN effect sizes when PER is set to zero.  

24) Now runs robust ANOVAs 11 times with 4999 sims (by default) and then reports median p-value and whether twice the standard deviation of the p-value exceeds the alpha threshold, in which case the results include the notation that the p-value was “(not confirmed)”. 

25) If effect size d* is made positive, confidence interval signs also flipped.  

26) Includes warning summary of %age of bootstrapping simulation runs with singular and nearly singular matrices in the ANOVA output files.
