dear arno and scott,
I have some datasets with bipolar scalp channels (e.g. Fp1-F7 or P3-O1).
I'm trying a solution to convert this format in one that EEGLab can
read, so that it's possible to compute time/freq scalp maps.
I've seen that a function improved to do this already exists:
can you tell me more about its usage?
I tried to write a function of this format:
[newdata chlab] = daisy2ref2( EEG.data, 'ref', 'common','chanlocs',
'Standard-10-20-Cap19.locs', 'badchan', 1:18);
but it doesn't seem to work, maybe because i don't know what good/bad
electrodes are (this warning message appears: Subscripted assignment
dimension mismatch. Error in ==> daisy2ref2 at 91 tmpdata(goodelec,:)
can you help me?
