[Eeglabnews] EEGLAB 4.5beta and 4.42stable are now available

EEGLAB 4.5beta and 4.42stable are now available for download at

http://sccn.ucsd.edu/eeglab/

EEGLAB 4.42stable fixes an important problem in EEGLAB4.41stable when 
filtering continuous data with portions of data removed (i.e., 
containing EEGLAB break events).

EEGLAB 4.5beta contains a variety of upgraded functions compared to 
EEGLAB4.42stable (erpimage(), eegplot(), ...) as well as increased 
support for Matlab 7. We have tested EEGLAB with Matlab 7.0.0.19901 
under Linux and Matlab 64-bit 7.0.0.1277 release for Opteron 64-bit 
computers under Linux. Matlab 7.0 seems to generate similar crashes 
under Linux and Windows (not tested yet).

There are still problems remaining when running Matlab 7.0 (Windows and 
Linux): some plotting functions (topoplot(), envtopo()) have a tendency 
to plot over other figures (i.e. the main EEGLAB graphic interface). We 
think these problems are due to the Java Virtual Machine as they 
disappear when the Java Virtual Machine is deactivated. To run Matlab 
without the Java Virtual Machine under Windows Dos prompt or Unix 
prompt, type

 >> matlab -nojvm

More details about EEGLAB releases follow:

4.5beta, Sept 13, 2004

    * *BIOSIG*: The BIOSIG plugin is now part of the standard EEGLAB
      distribution (see the plugin
      <http://www.sccn.ucsd.edu/eeglab/plugins.html> page).
    * *erpimage()*: added option to sort by amplitude in a rectangular
      time/frequency window rather than by amplitude at one time and
      frequency only. Plotted and output the correct sortvar order for
      trial sorting by amplitude.
    * *eegplot()*: added option to hide event duration.
    * *eeglab()*: added check of consistency between EEG and ALLEEG
      variables.
    * *pop_topoplot()*: changed default ordinate orientation for ERPs to
      positive-up.
    * *loadtxt()*: fixed reading comma-separated file (thanks to Petr
      Janata).
    * *envtopo()*: fixed x-axis label.
    * *pop_resample()*: can now resample data epochs (not recommended).
    * *pop_selectevent()*: fixed function crash when multiple events are
      entered with quotes.
    * *plotdata()*: fixed Matlab 7 plotting error.
    * *erpimage()*: fixed Matlab 7 plotting error.
    * *pop_prop()*: fixed Matlab 7 plotting error.
    * *plottopo()*: fixed Matlab 7 plotting error.
    * *pop_readbdf()*: Matlab 7 compatibility (bitand function call).
      This function is now part of the BIOSIG toolbox.
    * *pop_saveset()*: under Matlab 7, save dataset files compatible
      with Matlab 6.
    * *eeg_checkset()*: fixed event checking procedure for Matlab 7.

4.42stable - Sept 13, 2004

    * *pop_eegfilt()*: fixed filtering continuous data with break events
      and Matlab 7.0 compatiblity issue.
    * *eeg_insertbound()*: fixed error when inserting new boundaries
      (breaks) to data having boundary from previous EEGLAB versions
      (thanks to Johannes Sarnthein).
    * *pop_rmbase()*: fixed text in GUI and header inconsistency about
      time unit.
    * *eegfilt()*: fixed minor min filter length problem (thanks to Rami
      Niazy).
    * *pop_prop()*: fixed minor typo.
