mri_cor2label --i ./R2Mask.nii.gz --l ./R2s.label --id 1
made sure that it looks ok when I read in hi-res to tkmedit and

And got the output (pasted below), showing that the output is all zero.
Output is fine without label, or with -cortex.
I've also tried this with a conformed version of the label (also
verified in tkmedit) and have had the same thing. (I thought
maybe it was applying it to orig vol, which I admit would be
strange).(I noticed someone had a similar issue a couple of
years ago, but it involved a surface rather than volume label,
and looked like it had been resolved).
Am running current stable version on Mountain Lion.

Oh, the label should be a surface label. mri_cor2label creates a volume
label (basically it just means that each label point corresponds to a 1mm3
cube instead of a verex -- the vertex numbers should all be -1). Try
running vol2surf on the mask (using nearest interp) to create a surface
mask. Then create a surface label with mri_cor2label using the --surf
option.

Hi Doug
I've actually tried both inclusive and exclusive and have failed - just
checked again in tkmedit that the label was coming up correctly and it
was.
Just to double-check - the label should be in the space of the --mov,

Thanks!

Hi Fred, that mask is an inclusive mask, not an exclusive mask. Try
inverting you mask.

Dear all
I am painting some higher-res anatomical data from a volume to a surface,
and want to use a mask that excludes the vessels. (The same data but 1x1x1
conformed were used to create the surface).
I've created a binary label in the same space
mri_cor2label --i ./R2Mask.nii.gz --l ./R2s.label --id 1
made sure that it looks ok when I read in hi-res to tkmedit and display
label,
then ran mri_vol2surf
mri_vol2surf --mov ./sPQ07082012-0009-1-000208-01_R1.nii
--regregister.dat --surf-fwhm 4 --hemi $hemi --projfrac $frac --interp
trilinear --out_type w --mask R2s.label --o ./dancar-0.5-lh.w
And got the output (pasted below), showing that the output is all zero.
Output is fine without label, or with -cortex.
I've also tried this with a conformed version of the label (also verified
in tkmedit) and have had the same thing. (I thought maybe it was applying
it to orig vol, which I admit would be strange).(I noticed someone had a
similar issue a couple of years ago, but it involved a surface rather than
volume label, and looked like it had been resolved).
Am running current stable version on Mountain Lion.
Thanks for any pointers,

Re: [Freesurfer] unit of corpus callosum segmentation

[Freesurfer] recon-all problems [solved]
I had several problems testing freesurfer 5.2 installation, as previously posted. Now it is all OK and I would like to share what I could learn: 1- It does not work on Fedora 18 (segfaults with all tests with tkmedit, tksurfer and recon-all) that is due to a restriction imposed by glibc (only newest version). Only freeview works under Fedora 18 but, even here, I got a misalignment problem among surfaces and volumes. More details at https://bugzilla.redhat.com/show_bug.cgi?id=905638 2- I got partial functionality using VirtualBox (4.2.8 and 4.2.10). I cannot say about previous versions and the latest one (4.2.12 was released on Apriil, 12th). But I had problems with both virtual machines I tried: CentOS6 (fresh install) and the Xubuntu + FreeSurfer 5.1 vdi file I downloaded from FreeSurfer website. Tkmedit, tksurfer and freeview all worked but recon-all failed all time. 3- Fedora 17 and CentOS 6 work flawlessly out of box if you do not use virtualbox. Probably, other distros will work too, except if they are using the latest glibc (2.16-30). So my final setup is a dual boot machine: Fedora 18 (day-by-day tasks) and CentOS6 (freesurfer tasks). You can do it with only one disk but it is a lot easier with two.

Re: [Freesurfer] QDEC questions

'nuisance' variates are like any other. 4. depends on the expected 'blob' size 5. the selection of fwhm in qdec corresponds directly with the values selected by qcache (they are one-to-one related, ie the 10mm fwhm values created by qcache are used by the 10mm fwhm selection in qdec).

I know that discrete factors cannot be taken as nuisance factors, but it seems they also can't be taken as covariates.

Re: [Freesurfer] recon-all for multiple subjects using for loop
Hello, In our lab, we create a txt file with all the subject names (as they appear on their respective folders). Name that txt file whatever you want (like * subs.txt*) and save it somewhere in one of the paths (we use /Users/* Home_User*). Then in terminal, after setting the environments for Freesurfer and the subjects directory, insert the following: for SubjectName in `cat *subs.txt*` do recon-all -s $SubjectName -all -qcache done Make sure you have the ` (not ') on either side of the cat command or it won't work. This works for us and we have 200 subjects. Good luck, -David Vazquez, M. A. Graduate Student, University of California Riverside NSF Graduate Student Fellow dvazq...@ucr.edu 951-827-5243 Dept.
