[Eeglabnews] EEGLAB version 4.51 (stable) is now available

[Arnaud Delorme]

EEGLAB version 4.51 (stable) is now available from 
http://www.sccn.ucsd.edu/eeglab/

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.
With few exception, all the EEGLAB functions are backwards compatible 
with previous releases.
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).

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).

We have made the following modifications since the 4.5b release:

    * *pop_saveset(), eeg_checkset()*: 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.
    * *envtopo(), pop_envtopo()*: 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.
    * *erpimage*: made the optional spectrum plot and max frequency
      computations consistent by using the same spectral estimate.
    * *eeg_checkset()*: 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!
    * *eeg_getepochevent()*: can now process string fields.
    * *pop_selectevents()*: fixed boundary event renaming problem
      (thanks to Andreas Widmann).
    * *pop_topoplot()*: fixed dipole plotting error.
    * *topoplot()*: added optional argurment 'plotchans'.
    * *runica()*: fixed block length bug for some very short data
      lengths (thanks to Julie Onton).
    * *eeglab(), eeg_context(), eegplot(), erpimage(), pop_rejepoch()*:
      adapt all occurrences of && to & and/or || to |, for compatibility
      with Matlab r12 and older.
    * *pop_chanedit()*: 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.
    * *eeg_insertbound(), pop_eegplot()*: fixed event latency problem
      when inserting several boundary events in continuous data with no
      events (thanks to Elena Orekhova).
    * *tftopo()*: new title option.
    * *pop_reref()*: fixed channel label problem (thanks to Morgan Hough).
    * *eeg_context()*: fixed minor problems.
    * *pop_mergeset()*: now insert boundary event in EEG.urevent as well
      as EEG.event for context searching.
    * *pop_crossf()*: fixed "plot coherence phase" button (thanks to
      Stefan Debener).
    * *timef()*: added 'itcphase' output.
    * *pop_loadeeg()*: fixed the typo bug ('\' instead of '/') (thanks
      to Mari Zoltan, Hovagim Bakardjian, and Bernie C. Till).
    * *pop_loadcnt()*: fixed 1-point offset error when reading '.cnt'
      file events (thanks to Andreas Widmann).
    * *loadcnt()*: now force to read little endian format (for Solaris,
      Datastar, ...) (thanks to Timothy Uy).
    * *pop_readegi()*: now allow to read portion of segmented data file.
    * *Biosig()*: use latest Biosig functions.
    * Incorporated all minor fixes from 4.43stable.
