Hi, I
downloaded the new version of
mris_convert, but I’m having trouble getting it to run successfully.
When
I start with bfloats it says freadFloat: fread failed a bunch of times,
and starting
with a COR file it says it can’t allocate memory. How do I specify the
mgh
format you recommended when I run mris_glm?
Thanks,
-Aaron-
I'd recommend using mgh instead of bfloat, but in either case you'd do
something like:
mris_convert -c beta.mgh $SUBJECTS_DIR/yoursubject/surf/lh.white
beta.asc
(or use beta.bhdr for bfloat).
The ability of mris_convert to read any "volume" format was added
fairly recently, so if yours does not do it, you can get a new one from:

Great,
thanks.
One more
question. Doing it the mris_glm way,
is there somehow I can turn the beta files (bfloat) into ascii surface
format?
Thanks,
-Aaron-
The easiest way is probably to
build an average
subject (make_average_subject). This will create ?h.thickness in the
surf dir
which will be the average across the input subjects. You could also use
mris_glm with a design matrix of all 1s. The beta output will then be
the
average thickness.

Hi, I feel
like I used to know this,
but how do I make a map of average thickness for a group of subjects?
Also, is
there a way I can make a similar map showing the variance of thickness
values?
Thanks,
-Aaron-
