EEGLAB version 4.51 (stable) is now available from <a
class="moz-txt-link-freetext" href="http://www.sccn.ucsd.edu/eeglab/">http://www.sccn.ucsd.edu/eeglab/</a>
<br>
<br>
This upgrade is recommended because of major improvements and bug fixes
for Matlab 7.
We strongly advise to use Matlab 7 service pack 1 which fixes major
plotting bugs in Matlab 7.0.<br>
With few exception, all the EEGLAB functions are backwards compatible
with previous releases.
<br>
When you uncompress EEGLAB, along with the "eeglab4.51" folder, a
"biosig" folder will be created
so EEGLAB can use Biosig toolbox features to import a large range of
data file types (thanks to Alois Schoegel).
<br>
<br>
EEGLAB also comes with two new default plugins. One plugin (contributed
by Max Pozdin) performs
non-linear (IIR) filtering that can be applied to short data epochs.
Another plugin (contributed by Andreas Widmann) imports binary Brain
Vision Analyser data file (and events). <br>
<br>
We have made the following modifications since the 4.5b release:<br>
<ul>
<li> <b>pop_saveset(), eeg_checkset()</b>: If the 'File >
Maximize
Memory' option to save the data in the .set file is Disabled (not the
default), save EEG.data in a separate .dat float data file as a
*transposed* matrix (e.g., indexed by time, for continuous data as in
EEG.data'). We recommend using this option, as future component
clustering and dataset comparison features of EEGLAB will then allow
quick reading of single channels one at a time. Backwards compatibility
with the previous non-transposed .fdt files was maintained. </li>
<li> <b>envtopo(), pop_envtopo()</b>: fixed abscissa unit
problem. Changed optional argument keywords for better usability
(preserved backward compatibility). Debugged 'vert' flag (now uses
msec). Changed component selection criterion (back) to maximum variance
('mv'). Minor plotting edits (thanks to Keun Lee) and other small
improvements. </li>
<li> <b>erpimage</b>: made the optional spectrum plot and max
frequency computations consistent by using the same spectral estimate. </li>
<li> <b>eeg_checkset()</b>: fixed problem with events reading
under Matlab 7. WARNING: UNDER MATLAB 7 AND EEGLAB VERSION 4.5b, IF
EVENT TIMES WERE IMPORTED FROM A DATA CHANNEL, SOME EVENT TYPES MAY
HAVE ERRONEOUSLY BEEN SET TO BE THE SAME FOR ALL EVENTS! </li>
<li> <b>eeg_getepochevent()</b>: can now process string fields. </li>
<li> <b>pop_selectevents()</b>: fixed boundary event renaming
problem (thanks to Andreas Widmann). </li>
<li> <b>pop_topoplot()</b>: fixed dipole plotting error. </li>
<li> <b>topoplot()</b>: added optional argurment 'plotchans'. </li>
<li> <b>runica()</b>: fixed block length bug for some very short
data lengths (thanks to Julie Onton). </li>
<li> <b>eeglab(), eeg_context(), eegplot(), erpimage(),
pop_rejepoch()</b>: adapt all occurrences of && to & and/or
|| to |, for compatibility with Matlab r12 and older. </li>
<li> <b>pop_chanedit()</b>: added limited channel type support
(will be develop further in future versions - we recommend entering
channel types via the 'Edit > Channel Locations' menu window). Fixed
a problem under Matlab 5.3. </li>
<li> <b>eeg_insertbound(), pop_eegplot()</b>: fixed event latency
problem when inserting several boundary events in continuous data with
no events (thanks to Elena Orekhova). </li>
<li> <b>tftopo()</b>: new title option. </li>
<li> <b>pop_reref()</b>: fixed channel label problem (thanks to
Morgan Hough). </li>
<li> <b>eeg_context()</b>: fixed minor problems. </li>
<li> <b>pop_mergeset()</b>: now insert boundary event in EEG.urevent
as well as EEG.event for context searching. </li>
<li> <b>pop_crossf()</b>: fixed "plot coherence phase" button
(thanks to Stefan Debener). </li>
<li> <b>timef()</b>: added 'itcphase' output. </li>
<li> <b>pop_loadeeg()</b>: fixed the typo bug ('\' instead of '/')
(thanks to Mari Zoltan, Hovagim Bakardjian, and Bernie C. Till). </li>
<li> <b>pop_loadcnt()</b>: fixed 1-point offset error when reading
'.cnt' file events (thanks to Andreas Widmann). </li>
<li> <b>loadcnt()</b>: now force to read little endian format (for
Solaris, Datastar, ...) (thanks to Timothy Uy). </li>
<li> <b>pop_readegi()</b>: now allow to read portion of segmented
data file. </li>
<li> <b>Biosig()</b>: use latest Biosig functions. </li>
<li> Incorporated all minor fixes from 4.43stable.</li>
