Dear Users:
Brainstorm Alpha release 09-July-2004 is now available at
http://neuroimage.usc.edu/brainstorm/Downloads.php
->> Note this might well be last release before summer break <<-

See you all back in September !

Recent changes are:
09-July-2004
- Data averaging within a study is now operative:
Access is through DataViewer -> Basic Processing -> Average
Select data files within current study folder
Enter a value in ms for acceptable time-jitter about
some time-locked event (default is 0)
Selected data files are then averaged, with adaptation
of time window if original data don\'t have same lenght
or time limits and stored in a BrainStorm data file
within current study folder.
- Data filtering is now operating again (-> Matlab Signal Processing Toolbox is required):
Access is through : DataViewer -> Basic Processing -> Filter
A new GUI is created and offers the possibility to
- bandpass filter data using a zero-phase filter
- for EEG : move to average-reference potentials, once bad channels were removed
- Fixed bug when importing from CTF markers: some time clipping may occur
when requested time window about a marker occurence would end up having
an edge outisde the trial time limits. A message is now issued within
DS2BRAINSTORM stating that time clipping has occured and related event
data files have now a Time variable with proper length
- Fixed bug in 2D layout measures display: DataViewer -> DataViewing ->
2D layout
- EXTRACT_CHANNELS: Fixed bug for CTF computation when first MEG channel containing coef
correction information is declared as BAD: store coef
information in first good MEG channel and trim number of
lines of correction matrix to proper number of good MEG
channels only (crucial when running RAP_MUSIC estimation).
- Minor change to DataViewer GUI layout : direct access to Averager and
and Filter
- Moved obsolete code to Archive:
[filter_win.m and .mat] + [mri_scan_params.fig and .m] + [waves_multi.m and
.mat]
08-July-2004
- Fixed miscellaneous file access issues encountered under Linux (e.g. during data import)
07-July-2004
- Fixed uicontext menu bug under Linux in DATA_MANAGER: could not load
data using right click.
- Fixed minor SUBJECT_EDITOR bugs:
.new values for field entries of the
subject file are now properly displayed at once when user click on \'save\'
button;
.Date of Modification field is automatically set to current day\'s date when subject file is updated
.Anatomy-> Import now properly calls BST_MRIVIEWER (was still calling older MRITool)
06-July-2004
- Import raw MRI: Axial/Sagittal/Coronal pulldown menu switch is now
operative.
The phantom data set has not changed and remains the 16-June version.
