unit in 'search area' in the glmfit log
by Jeni Chen 30 Oct '15

30 Oct '15

Hello, When running the Clusterwise Correction for Multiple Comparisons, I used a label as a mask to restrict search area. I want to find out the size of that label, so I guess I can pull that information out from the "mri_glmfit.log", specifically under 'searchspace'? Also I only see a numerical value there, I assume it is in mm2? Thanks. Jeni

average z-score of each subject from a common cluster
by stdp82＠virgilio.it 30 Oct '15

30 Oct '15

Hi list,I have two queries, please. I'd like to have the z-score from my rsfMRI data (seed-analyis). 1) I have extract the z-score from the Vtx Max In details, after groups comparison analysis, I have opened the cache.th13.pos.sig.cluster.summary contained in group.diff folder and I have read the Vtx Max coordinates.Next, I have open the z.nii.gz of each subject and I have expected the z-score from the vertex which have the Vtx Max coordinates. Is this procedure corrected? 2) z-score of each subject from a common cluster I would like to use the cluster which shows the group difference (cache.th13.pos.sig.cluster.nii.gz) as ROI mask. Thus, I would extract from it the average of the z-score which is contained in each subject.How should I do? Thanks. Stefano

lables id in a new aparc+aseg file, created from laus250 parcellation
by Peled, Noam 30 Oct '15

30 Oct '15

Hey all, I used mri_aparc2aseg to map the cortical labels from the laus250 parcellation. Now I need to create a new lookup table, mainly for displaying the labels' names in freeview. How can I know what id each label gets in my new laus+aseg.mgz file? Thanks, Noam

How can I convert Martinos Center dicoms to the dicom format that dcm2niix recognizes?
by Emad Ahmadi 30 Oct '15

30 Oct '15

Hi Freesurfer experts, I hope you’re all enjoying your day! Working in Launchpad, I want to extract the bvals/bvecs from DTI dicoms obtained at Martinos Center. The dicoms have the following format: MR1.3.12.2.1107.5.2.32.35006.2010052613553219211129919 MR1.3.12.2.1107.5.2.32.35006.2010052613553736471330196 MR1.3.12.2.1107.5.2.32.35006.201005261355429098330464 ... I receive error when I run dcm2niix (to extract the b values and b vectors): Command: dcm2niix -f dti <folder of dicoms> The error I receive: Warning: output folder invalid MR1.3.12.2.1107.5.2.32.35006.2010052614044051320551992 will try Error: unable to find any DICOM images in Conversion required 0.000000 seconds. When I do the following steps to generate “treatable” dicoms, dcm2niix recognizes these dicoms: 1. copy Martinos Center dicoms to my local Mac 2. import dicoms into OsiriX 3. Export them as dicoms 4. copy the OsiriX-exported dicoms back to Launchpad 5. Run dcm2niix on the new dicoms Since this copying back and forth takes a lot of time, I need a better way to convert the “crazy” Martinos Center dicoms into the “treatable” ones! I would really appreciate your help.

License for a University HPC cluster
by Mike Croucher 29 Oct '15

29 Oct '15

Hi I am one of the sysadmins of a University HPC cluster. We've had a request to install Free Surfer and I note the need for a license. If I request one of these licenses, will we be permitted to install it such that all users of the cluster can access it or does each individual user need their own license? Best Wishes, Mike

comparison of 4 groups: mri_glmfit or Qdec?
by Sandy Schramm 29 Oct '15

29 Oct '15

Dear Experts, we want to compare data (thickness) of 4 groups (3 morbid groups and 1 controll group). Both, Qdec and mri_glmfit, will do the same analyses. But we are not sure, if the usage of Qdec is statistically correct in our case. Because in Qdec we can only compare 2 of the 4 groups. But Qdec is much more comfortable to handle. Or do you advise the mri_glmfit for our data analyses? Thanks for some advice! Sandy Schramm

How to realign a surface in matlab to a realigned parent volume
by Octavian Lie 29 Oct '15

29 Oct '15

Dear All, I ran recon-all and generated a brain.mgz and say, lh.pial. I converted brain.mgz to brain.nii, imported the latter to matlab/spm and realigned it to rbrain.nii, generating a transform matrix M=rbrain.reorient.mat. if MM is the header for rbrain.nii, the header O for the original brain.nii can be calculated with O=inv(M) *MM. How do I reorient the lh.pial to the rbrain.nii? I suppose I need a reader for the pial header in matlab. Many thanks, Octavian
