[Eeglabnews] EEGLAB version 4.31 now available

[Arnaud Delorme]

 EEGLAB version 4.31 is now available from http://www.sccn.ucsd.edu/eeglab/

This upgrade is recommended because of major improvements and bug fixes.
All the EEGLAB functions are backwards compatible with previous releases.
Thanks to Zoltan Mari, Stefan Debener, William Gehring, Ruey Song Huang, 
Vladimir Litvak, Teresa Ka Wai Wong, Ingmar Gutberlet, Marcel 
Bastiaansen, and others for suggestions.

We have made the following modifications since the 4.301 release

4.31 - February 13, 2004

    * *Tutorial*: two new sections (I.2.2 and I.2.3) were added to the
      channel editing tutorial.
    * *Channel location*: can now use channels without coordinates
      (e.g., EYE, EMG...). There are simply ignored when plotting scalp
      maps. Automatically read channel names from binary files for EEG
      and BDF files and look up standard channel locations (using menu
      Edit > Channel location) based on channel labels (assumes 10-20
      channel labels). Functions affected are pop_chanedit(),
      convertlocs(), topoplot(), pop_headplot(), headplot(), plottopo(),
      pop_loadcnt(), pop_loadeeg(), and pop_loadbdf().
    * *spectopo(), spec()*: fixed the spectrum computation when the
      Matlab Signal Processing Toolbox is not present.
    * *pop_comperp()*: added command line options 'tlim' and 'ylim'
      (thanks to Stefan Debener's suggestion); fixed the output problem
      (thanks to William J. Gehring).
    * *pop_timef()*: fixed multitaper (frequency assignment was wrong).
    * *pop_reref()*: fixed rare error due to channel location structure.
    * *erpimage()*: added 'showwin' flag argument to image the sorting
      window used in sorting by phase, amplitude or value.
    * *timef()*: added 'erspmax' argument to fix color scaling for ERSP
      (thanks to Ruey Song Huang).
    * *pop_editset()*: fixed command line call error when function was
      called from a subfunction (thanks to Vladimir Litvak).
    * *pop_runica()*: fixed conflict between 'pca' option and automatic
      rank lowering (thanks to Teresa Ka Wai Wong); fixed history
      generation.
    * *pop_mergeset()*: now adds a discontinuity ('break') event when
      merging two datasets.
    * *pop_loadcnt(), pop_loadeeg(), pop_loadedf(), pop_loadbdf()*: now
      import channel labels.
    * *pop_rejmenu()*: fixed standard threshold rejection time limits
      previously interpreted as sec instead of ms (thanks to Zoltan Mari).
    * *pop_loadbva()*: new function to load Matlab files saved using
      Brain Vision Analyzer (thanks to Ingmar Gutberlet and Marcel
      Bastiaansen for their help).
    * *pop_copyset()*: fixed history generation.
    * *pop_chanedit()*: fixed local history generation in dataset.
    * *pop_topoplot()*: fixed history generation.
    * *pop_importevent(), pop_importpres()*: new option to automatically
      adjust the sampling rate of the new events so they best align with
      the closest old event. This may take into account small
      differences in sampling rates that could lead to big differences
      by the end of the experiment (e.g., a 0.01% clock difference
      during would lead to a 360-ms difference after one hour if not
      corrected). Also, for the Presentation file, users can now select
      any file fields for event latency and type.
    * *pop_rejepoch()*: fixed problem when all or no trials were
      selected for rejection.
    * *pop_editset()*: fixed command line call error when function was
      called from a subfunction (thanks to Vladimir Litvak).
