[Erppcatoolkit-support] ERP PCA Toolkit 2.33 release

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

New release of EP Toolkit.  Major feature additions include addition of filtering options, support for manual editing of bad channels and trials, and support for ERPlab file format.  Continuing improvements in support of spectral data and ongoing bug fixes and refinements to existing features.

Cheers!

Joe



1) Added option to set last row to be imported in text files.
2) Fixed crash when changing the sampling rate in the Samples subpane of the Edit function.
3) Fixed subNames, subTypes, cellNames, cellTypes, facNames, and facType fields generated by single file mode and by PCA output and by Transform data not necessarily being column vectors, resulting in crashes in other parts of the Toolkit.
4) Fixed crash when invoking 2D plots in Topos view.
5) Fixed crash when using combining cells or chans for spatial PCA data.
6) Fixed Transform not updating reference type when rereferencing data.
7) Fixed missing markers in Wave plots when data range is less than one.
8) Fixed crash under certain circumstances when windowing data with multiple channels in a channel group.
9) Added option to do internal calculations of frequency data in either amplitude or power form.
10) Fixed erroneous error message and crash when trying to PCA average file where bad channels were dropped rather than replaced.
11) Fixed error message when expanding channel for waveform plot for which the data are no longer available.
12) Fixed not changing prestimulus period in Transform function when reference set to "none."
13) Added frequency filtering (low pass, high pass, bandpass, bandstop, notch) to Transform function.
14) Fixed subNames and subTypes field not being a column vector when averaging multiple files, resulting in no average file being saved.
15) Detects when PCA yields complex numbers due to rounding errors causing relationship matrix to be unsymmetric and makes the relationship matrix symmetric.
16) Since eigenvalue decomposition during PCA is not always in ascending order, sort them first.
17) Handles situation where FFT data has negative values (e.g., due to imprecision in PCA results) and transforming to dB would result in complex numbers, by taking absolute value first.
18) Events assigned to wrong subject (off by one) when reading in average files.
19) Added support for reading .set files generated by Widmann's pop_grandaverage function.
20) Added support for reading .erp files generated by ERPlab.
21) Fixed erroneous "labels" error message when trying to load .study file.
22) Fixed error message when applying PCA to data with only one cell.
23) Fixed problem that loading EP files with frequency PCA data results in damaged data file and error messages.
24) Fixed problem where information for expanding channels in waveform plot is lost under some circumstances.
25) Added option to contextual menu in Topos view to rescale figures according to selected topo map.
26) Fixed bug in reconstruction of PCA data from frequency-domain PCAs.
27) Added markers and expanding window to waveform figures in Topos.
28) Added manual scanning for bad channels and trials.
29) If baseline correction chosen, will occur even if blink correction not performed and it will be applied prior to global bad channel and trial detection.  Detrending now performed prior to global bad channel and trial correction and baseline correction.
30) Fixed crash when trimming low end Hz of spectral data using Edit function.
31) Fixed identifying all EGIS files as Hydrocel-128P under OS X 10.8 when using Satimage osx.
32) Added frequency-domain peak measures to windowing function.
33) Fixed crash when combining channels for factor data under certain circumstances (presence of facData due to adds).
34) When saving a dataset, name of dataset changes if new name is chosen for saved dataset.
35) Fixed a variety of issues with the automatic scaling in the topomap figures, especially for spectral data.
36) Fixed error message when generating PCA data from a single subject average.
37) Fixed crash in View pane under when changing a dataset under certain circumstances.
38) Marker fields in View pane no longer reset to blank whenever a change is made in the settings.
39) Clearing volt, hz, and sample parameters in View pane no longer crashes.  If value is manually set, will not change until a new dataset is chosen or until the value is cleared (in which case it will be replaced with automatic value).
40) Added writing ERPlab format files.
