Hello,
I'm trying to prepare my diffusion data with track-all -prep but
"trac-preproc exited with ERRORS"
I think it is related to the FSL instructions, because it gives this
message in the beginning:
<...>
flirt: error while loading shared libraries: libnewimage.so: cannot open

It's solved,
The problem has been solved by adding a line to .bashrc file.

Previously I manually corrected the FSL_DIR in the tcsh shell, were I run
the Freesurfer, using:

Ops... I did not see these replies before! Thank you, both!!
Christopher, the command line works great. I also found the --viewport and the
--ss, which is exactly what I was looking for!
I will try the dev version that Anastasia suggested.
Thanks a lot, Amelia

I think that the ces is the better map to use, but there's not a
consensus. For some reason that I don't understand, people starting
using the z-map or the correlation coefficient as the input to the group
level in contradiction to everything that had ever been done in
task-based analysis. In
Hi Surfers,
I want to find a way to analyze subcortical activities in native space
and still take advantage of per-run registration. As far as I understand,
this is not possible in current preproc-sess. We need one extra step in
which we have to map all fmcpr.nii.gz files to subject's orig.mg
Thanks! Would you please explain why you think ces is the better map (vs z or
correlation coefficient)?
Thank you

The statistic maps (z, t, correlation coefficient) depend on the noise

correlation but have different correlation coefficient or z because one

Thanks! Are both the ces and cespct normalized? Is there a reason you would use
one over the other?

What do you mean by normalized? The intensity is normalized in both, ces
to the grand mean over the brain, and cespct to the voxel mean. I've
done experiments with both and can't find a big difference (though I've
not looked in resting state). I usually just use ces

Hi Alex, mris_preproc produces a stack images (27 in the first case and
16 in the 2nd case). For some reason the first two images are the same
in both stacks. This is the way that you have run the program because
both calls to mris_preproc use
NNC0035_pet_lh.mgh and NNC0045_pet_lh.mgh as the f
Yes. Note that that will produce huge files (float images 256^3 by
number of time points).

Hi,
How does event length/duration contribute to an FS-FAST analysis. Will
I produce different results, if I specify an event length of 1 second
versus an event length of 0.1 seconds? Most importantly, if yes, how
will they differ?
The reason I am asking is formerly I would use the actual duratio
It depends on how long your event is. For most designs where the events
are on the order of seconds it should not make much of a difference. For
very short events, I'm not sure.

Dear list,
I would like to make some plots based on the centerpoint of an ROI, so I
would like to head if it possible to extract the centerpoint of the ROIs
from a parcellation (e.g. the Desikan-Killiany Atlas). By the center
point I mean the 3d coordinate, it is not crucial that it is the center
just read in the label of the roi of interest and read in the
respective lh/rh.white (if interested in the white surface) and take
the average of those labels 3d points (note, this will do strange
things: not be on the surface. It may not even be in Brain tissue). If
you then want to be on a vertex
