EEGLAB version 4.31 is now available from
<a href="http://www.sccn.ucsd.edu/eeglab/" class="moz-txt-link-freetext">http://www.sccn.ucsd.edu/eeglab/</a><br>
<br>
This upgrade is recommended because of major improvements and bug
fixes. <br>
All the EEGLAB functions are backwards compatible with previous
releases.<br>
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.<br>
<br>
We have made the following modifications since the 4.301 release<br>
<br>
4.31 - February 13, 2004
<ul>
<li> <b>Tutorial</b>: two new sections (I.2.2 and I.2.3) were added
to the channel editing tutorial.
</li>
<li> <b>Channel location</b>: 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().
</li>
<li> <b>spectopo(), spec()</b>: fixed the spectrum computation when
the Matlab Signal Processing Toolbox is not present.
</li>
<li> <b>pop_comperp()</b>: added command line options 'tlim' and
'ylim' (thanks to Stefan Debener's suggestion); fixed the output
problem (thanks to William J. Gehring).
</li>
<li> <b>pop_timef()</b>: fixed multitaper (frequency assignment was
wrong).
</li>
<li> <b>pop_reref()</b>: fixed rare error due to channel location
structure.
</li>
<li> <b>erpimage()</b>: added 'showwin' flag argument to image the
sorting window used in sorting by phase, amplitude or value.
</li>
<li> <b>timef()</b>: added 'erspmax' argument to fix color scaling
for ERSP (thanks to Ruey Song Huang).
</li>
<li> <b>pop_editset()</b>: fixed command line call error when
function was called from a subfunction (thanks to Vladimir Litvak).
</li>
<li> <b>pop_runica()</b>: fixed conflict between 'pca' option and
automatic rank lowering (thanks to Teresa Ka Wai Wong); fixed history
generation.
</li>
<li> <b>pop_mergeset()</b>: now adds a discontinuity ('break') event
when merging two datasets.
</li>
<li> <b>pop_loadcnt(), pop_loadeeg(), pop_loadedf(), pop_loadbdf()</b>:
now import channel labels.
</li>
<li> <b>pop_rejmenu()</b>: fixed standard threshold rejection time
limits previously interpreted as sec instead of ms (thanks to Zoltan
Mari).
</li>
<li> <b>pop_loadbva()</b>: new function to load Matlab files saved
using Brain Vision Analyzer (thanks to Ingmar Gutberlet and Marcel
Bastiaansen for their help).
</li>
<li> <b>pop_copyset()</b>: fixed history generation.
</li>
<li> <b>pop_chanedit()</b>: fixed local history generation in
dataset.
</li>
<li> <b>pop_topoplot()</b>: fixed history generation.
</li>
<li> <b>pop_importevent(), pop_importpres()</b>: 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.
</li>
<li> <b>pop_rejepoch()</b>: fixed problem when all or no trials were
selected for rejection.
</li>
<li> <b>pop_editset()</b>: fixed command line call error when
function was called from a subfunction (thanks to Vladimir Litvak).
</li>
</ul>
