[Erppcatoolkit-support] EP Toolkit 2.91 released

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

EP Toolkit version 2.91 has been released:
https://sourceforge.net/projects/erppcatoolkit/ <https://sourceforge.net/projects/erppcatoolkit/>

The major feature upgrade is the option to use conventional ANOVA statistics rather than robust.  I still encourage folks to use robust statistics but it’s nice to have the option to use conventional statistics, especially for things that my robust statistics code doesn’t support yet, like covariates and G*POWER compatible effect size measures.  It also makes it easier to compare the two if you’re trying to make up your mind about using it.  Note that the conventional ANOVA statistics relies on Matlab’s Statistics Toolbox so it has to be part of your install.  I’ve confirmed that it seems to produce results identical to that of SAS and SPSS.

The major bug fix is to the option to drop trials during averaging according to behavioral measures, which wasn’t doing so correctly.  Also, the default for retaining trialwise SDs has been turned back to “none” as it was slowing things down during analysis too much.  Incompatibility problems with EGI datasets where channel names have been changed prior to importing into EP Toolkit have also been resolved.

Stay healthy everyone!

1) Fixed crash when plotting using subject SD option.  
2) Added support for preferences to manually specify screen size and screen position and RAM information.  
3) if new combined cell added via Edit>Cell was meant to be a difference wave and enough cells are bad that the weights no longer balance to zero, then treat as invalid rather than just crash.  
4) Fixed crash when using the "grand" button of Edit>Subjects subpane and there are missing values in the selected column.  
5) Changed automatic default upper VEOG channels to closer to eyes.  
6) Fixed crash in blink correction step of Preprocessing function when multiple boundary events are present in continuous data.  
7) Fixed cannot change settings in ANOVA function when the cells of the currently selected dataset are not listed in alphabetical order.  
8) Moved spike potential file template to separate file.  
9) Disabled autoTemplate option for spike potential correction since it doesn't seem to work. 
10) Improved template function's waveform display for the spike potential artifact.  
11) Fixed movement artifact correction step still not correcting the artifacts when there are NaN values present.  
12) For Window Data function, fixed subject labels always being output in alphabetical order, resulting in mismatch with the voltage data if the labels were not in alphabetical order.  
13) Fixed crash when reading an events text file with key codes.  
14) Fixed in conversion of EP files to EEGlab format, eloc labels were being saved as cells containing the labels, resulting in errors down the line.  
15) Fixed crash when reading in file format with fixed channels (e.g., text) and REF channels are specified in the CED file.  
16) Fixed crash when reading a file using a BV header and the recording was cut short so it ends on an incomplete TRSP.  
17) Fixed collision of findpeaks function in PrepPipeline with Matlab's own findpeaks function by putting it in a Private directory.  
18) Fixed crash when windowing multi-session data.  
19) Fixed crash in Edit function when using the Factors subpane with one-channel data.  
20) For Segment function, if there are no trial specs, will instead offer the key names, if any, of the event lock event for the ACC and RT popup menus.  
21) Resegmenting single-trial data no longer results in zero segments.  
22) Fixed crash in Segment function when there are no trial specs and the Task field is being used.  
23) In Average function, fixed erroneous error message about multiple task codes when there were task fields left empty.  
24) Fixed crash when preprocessing average data.  
25) In Preprocessing function, can still recognize EGI montages even when some of the electrodes have been renamed and the ced field is not a GSN montage name if at least half still start with 'E’.  
26) Changed default for trialwise SD back to "none" as it was causing functions down the line to take too long.  
27) Added cell to the single-file options in the Average function.  
28) Fixed crash when averaging file with no trial specs.  
29) Fixed crash when reading a continuous file with a boundary event that falls in the extra points that are appended to the last epoch.  
30) When reading data files, noInternal preference option now applies to .ept files as well.  
31) Contrast option of ANOVA function no longer crashes when only a subset of the columns were included.  
32) In Edit function, fixed crash if the trial-wise variance information was retained during averaging and there is an attempt to generate a cell difference wave where cells are bad for a subject.  
33) In Average function, fixed trials not being dropped correctly based on RT and ACC settings.  
34) Added option to ANOVA function for using conventional statistics instead of robust.  Includes ability to use covariates for ANCOVAs and effect size output suitable for G*POWER calculations (both conventional statistics only).  
35) Bonferroni post-hoc corrections upgraded to Dunn-Šidák (slightly higher alpha thresholds, around the fourth decimal).  
36) Fixed Transform function's baseline and rereference options not being robust to presence of NaN values.  
37) Fixed crash when changing channel types in Edit function.  
38) In View Topos function, fixed error when trying to produce 3D graph and there are regional EEG channels present.  
39) Fixed error message when appending subjects, as with the Edit function.  
40) No longer adding regional channel add in Window function if only one channel was used.  
41) Functions like Dipole Analysis can still recognize EGI montages even when some channels are missing as long as they are still labeled in the EGI manner (e.g., E11) or also an equivalent (e.g., EEG 11).  Also, can still recognize even if the file was not .mff or .set.  
42) Fixed crash in Save function when in Convert mode.  
43) Fixed crash in std subpane of QC pane of Edit function with some datasets.  
44) Fixed crash when importing data file with no internal electrode coordinates and no CED file has been selected.  
45) Added workaround for OS X Matlab bug where titles are not presented in file requestors.  
46) Fixed when adding channels as via CED files, the default type was SGL rather than EEG.
