Hi all, we're using 5.1 to analyze some single subject, event-related
functional data, and are getting some strangely high values for % signal change
when using func2roi-sess and roisummary-sess.
Here are the commands we're running:
func2roi-sess -s LMV2012_N01_heading -roidef rhmed_singlevsd
Hi Doug et al,
We're running into a problem doing a wrfx group analysis using
FreeSurfer 4.5. Looks like the glmfit is having trouble with the
weights. We tried running it for different subsets of our subjects,
and get the same thing, so it's not one subject contaminating the
analysis.
Hi all, we have a subject who had to end a run early, and as a result
his data is split over two sessions. The two sessions can't be
analyzed independently, since some events are missing from each, which
causes selxavg3 to fail. Instead, what I've been trying to do is take
the timecourses
Hi Doug et al,
I'm trying to import the polar and eccentricity maps resulting from a
retinotopy analysis into Matlab for some additional manipulation.
Specifically, what I'd like is to get something like the output from:
surf-sess -s sessid -a rtopy -retinotopy polar/eccen -flat
as polar an
