Hi Dougles,
Thank your for your reply. Now I am using FSFAST, but I didn't find flags
in prepro-sess which can be used in combing or dividing fMRI data. Using
the following code I could get three files for each run (left cortical
surface, right
If you just want to concatenate you can use something like
mri_concat 001/fmcpr.up.sm5.fsaverage.lh.nii.gz
002/fmcpr.up.sm5.fsaverage.lh.nii.gz
003/fmcpr.up.sm5.fsaverage.lh.nii.gz --o

are you trying to use FSFAST to do the entire fmri anlaysis? If so, then
follow the tutorial as it will handle the skipped TRs and the
concatenation for you. If not, then you don't need a paradigm file

It is probably trying to use a default bval and bvec file, but it can't
find it. If you have your bvals and bvects, try passing them explicitly
to dt_recon

Great! So I also need to subtract 8 seconds from the onset time of each
stimulus when I make the *paradigm file*, right? If the duration of
stimulus is smaller than 1 second, such as 0.05 second, do I need to change
its duration to 0 in a event-related

How can I discard the first 4 time points of each run during concatenating
several runs? I know I can skip the first 4 time points with the flag *-nskip
4* in configuring a analysis, but this condition can be only applicable
when each run is modelled
Sounds like you need an F-test, eg, create a contrast like
1 1 -1 -1 0 0 0 0 0 0 0 0
1 1 0 0 -1 -1 0 0 0 0 0 0
This tests the null hypothesis that p1==p2==control

Hello Freesurfer Developers,
I was going to reconstruct MPRAGE images from GE 3T machine.
First I used this command:
*dcmunpack -src . -scanonly scan.log*
It made just *scan.log* file for me. Then I used this command:
*unpacksdcmdir -src / -targ
You have to specify an output directory with -targ and the runs you want
to unpack with -run. See the help (ie, run dcmunpack with -help)

Hello Freesurfer devs,
Is there available any Desikian-Killiany and Destrieux atlas template or
image downloadable with all brain labels of the atlas? I would to use this
image to show my results in a lab meeting? I would need somethig similar
that
Hi Miguel
I think we distribute parcellations of the fsaverage subject (and of bert
and ernie), so if you have any of those you can use them to show the
atlas labels. The atlases themselves are more complicated and store other
information that isn't easily visualizable
cheers
Bruce
On Wed,
I'm not sure what you mean. The atlas is distributed with FS.

Hello Freesurfer devs,
Is possible segment the brain ventricles using Freesurfer in terms of mm3
or ml? I would be interested in study the ventricular enlargement. Is
possible with Freesurfer or other toolbox.
Any help would be appreciated. Thanks
Hi Miguel,
yes, we report ventricular volume in mm^3 in the stats files.
cheers

The first 2 commands you list are,

You can use the per-voxel regressor (--pvr) option to mri_glmfit. Search
through the mail archives for how to use it

When you ran mkanalysis-sess, did you specify two event types? You only
have one non-null event in your paradigm file.

Hello Freesurfer Experts,
I am wondering whether it is possible to apply the same manual edits (removing
GM/WM or adding CPs) to multiple scans. I have a dataset with ~100 scans per
subject acquired in quick succession and, interestingly, Freesurfer appears to
have the same issue in almost

Hi Ryan
it would be pretty trivial to do in matlab, so probably that is best,
although I don't understand what multi-frame volume you are using

Are you using FSFAST? If you run the preprocessing (preproc-sess), then
it will get you most of the way there.

If you are using output froom mri_segstats, then you need to use
asegstats2table, not aparcstats2table. It can be confusing ...

Use the first one. Not sure what you mean by your multiple comparisons
