275 CTF Channel datasets

[Darren Weber]

Hi Matthias,

we have a 275 channel CTF system at UCSF.  After learning a couple of things
from Tom, I have developed some matlab code for handling this data.  I have some
GPL code available in the ctf module of the cvs service at http://eeg.sf.net -
you can get it using the attached shell script, ie:

#########################
#! /bin/tcsh
echo ""
echo "press enter at the 'CVS password:' prompt, do not enter any text"
echo ""

cvs -d:pserver:anonymous at cvs.sourceforge.net:/cvsroot/eeg login
cvs -z3 -d:pserver:anonymous at cvs.sourceforge.net:/cvsroot/eeg checkout ctf
#########################


The data structure in matlab may be different from FieldTrip, but it should be
easy to convert to FieldTrip if necessary.  There are some easy command line
filter/baseline/plot functions.

Best, Darren
