Quarantined

Function	Update	Notes

C. Medica

Function	Update	Notes
epp_plotchannels	NEW	Plot ERPs per-channel in either a grid, or according to channel locations (Essentially, this is a stripped down version of eeglab's plottopo function).
epp_filter_by	NEW	Filter data in study by some variable in study.IDs table.
epp_matchsubjects	NEW	Use to remove subjects that are missing data in some conditions.
epp_extractIDs	NEW	Extract (and save) data from study.IDs tables.
epp_combineconds	IMPROVEMENT	Supports combining conds based on REGEXP.
epp_plotbutterfly	IMPROVEMENT	The trace parameter replaces all parameter.
epp_get*	IMPROVEMENT	All epp_get* functions now export the identification column with the correct name (ID).
epp_plot*	IMPROVEMENT	All plot functions are faster and more efficiant when exporting plot data to .csv.
f_WaveletConv	FIX	When creating wavelets via f_WaveletConv (formerly suppWaveletConv), baseline correcting no-longer stops on error.
epp_getTF	FIX	Fixed bug in epp_getTF that caused error when conditions were not of equal size N.

Modern-time Preacher

• [FIX] Fixed bug that caused trace plots to only showed the data of the first subject. (when using epp_plotbutterfly with 'all',true).
• [NEW] added option to plot trace plots for only a sub-set of channels.
• [NEW] When importing eeglab files for wavelet transformation:
  • Added option to use a constant number of cycles.
  • Added support for 2 types of baseline corrections (see suppWaveletConv for more info).
• [IMPROVEMENT] New color maps when plotting topos and time-frequency plots.
• [IMPROVEMENT] Better frequency-band selection when measuring TF and when plotting TF topos.
• [IMPROVEMENT] Better ersp color scale in epp_plotTF.
• [IMPROVEMENT] Better parameter saving in xlsx file (second sheet) when saving.

Oxygen Is Good for You

Changes to functions

These are the user-end changes to EPP-TB.

New functions

• epp_makegrands - average data per-condition. Good for plotting TF data without loading the full data-set.

Added features

• epp_getTF - major bug fix that caused plotted data to be flipped on the x-axis (time)!
• epp_plottopo - added option to plot average data across time window.

Minor Improvements

• epp_loadeeglab is now faster and more efficient when combining subject's data into a study struct.
• epp_get* - improved saving of condition names.

Exodus (sans bugs)

This is a release of a million little big fixes following the release of version 3.0.0.
See whats new in version 3.0.0.

Exodus

• Updated documentation to all functions.
• Added new README file. (issue #1)

Changes to functions

These are the user-end changes to EPP-TB.

New functions

• download_and_install_EPPTB running this function will install the latest stable version of EPP-TB from GitHub
• New import functions:
  • epp_loadeeglab imports .set files, and converts data to ERPs, or Wavelet transformation (see function help for more info).
  • epp_loadegimat (replaces epp_load).
  • epp_loaderplab (replaces epp_erplab_import)
• New measuring functions:
  • epp_getAmp (replaces epp_getamplitude) + added point amplitude method.
  • epp_getLat (replaces epp_getlatency)
  • epp_getTF (complete re-write)

Added features

• epp_combineconds now supports wavelet data.
• epp_plotTF improved support for scale limits.
• epp_plotbutterfly can now export plot to R.

Minor Improvements

• study structure no longer needs to have a field for sampling rate (previously study.samplingRate)
• study structure no longer needs to have a field for baseline (previously study.baseLine )

The Time (Frequancy) Warp

New functions

• epp_combineconds for combining conditions.
• epp_plottopoTF for plotting time-frequancy (power only) topos across frequancy-bands.

Support for time-frequency data

Gained support

The following function have gained support for TF data:

• epp_diffwave
• suppMatchSubjects

Improved support

The following functions have improved support for TF data: ITC (abs) is now computed by the functions, to allow for the combination of conditions.

• epp_getTF
• epp_plotTF

Other

• epp_plotgrands - minor improvment to R code.
• Improvemnt to the way all plotting functions add titles to the plots.
• Starting from this release, a .mltbx file will no longer be provided. Instead, install by adding the folder with sub-directories.

v2.2.3

Whats New in v.2.2.3

• [NEW]: epp_GFP - a new function for computing Global Field Power (Lehmann & Skrandies, 1984).
• [NEW]: epp_plotbutterfly - can now also plot all channels across subjects.
• [IMPROVMENT]: epp_plottopo - (in R) added function to mark channel groups (Thanks to Sveta Lisson for this).
• [IMPROVMENT]: epp_plottopo - added option to only plot channel locations.

Future Plans

Hey! EPP-TB is now on GitHub! That means:

• Issue reporting is now on GitHub
• The old OSF repository is dead... :(

The next major release (v3) will have some cool new functions, and better support for time-frequency analyses, as well as pulling data from EEGLAB's .set files.
So look forward to that.
