mri_surf2surf - Interpolation
by Gardus III, John D 10 Nov '15

10 Nov '15

Hello all, I'm in the process of mapping some non-FreeSurfer derived outcomes to a curv file containing the vertices of the pial surface mesh. I have values at roughly 100 vertices, leaving some 37000 with 'nan'. I then run an intra-subject surf2surf command in an attempt to interpolate between vertices for which I have values. The problem is that the NaNs pull the existing values down, resulting in a smearing/dilution of my outcomes. Is there any way to interpolate and make the intervening vertices purely a function of nearby vertices for which values exist?

Region specific stats
by Hassan bakhshi 10 Nov '15

10 Nov '15

Hi everyone, I could get all features from asegstats2table and aparcstats2table, Now I need stats by region, for example frontal lobe stats and etc. How can I get them??? Should I select by myself or there is an easy way?

Also, try removing the blank line at the end of wmh.levels, and make sure you have a carriage return at the end of long.qdec.table.txt. This may fix the 2nd error On 11/09/2015 10:38 PM, Heidi Foo wrote: > Dear Dr Greve, > > Thanks for your reply.

Are those the qdec files that generate the first error? That error implies that fsaverage is included as a subject in the qdec file. Is this possible?

mri_surfcluster statistics and label question
by Yang, Daniel 10 Nov '15

10 Nov '15

Dear FreeSurfer experts, In the output mri_surfcluster (e.g., https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysisClusterSu…) what is the statistics behind the Max? Is it either t-statistic (if only 1 line of contrast) or F-statistic (if two lines of contrast), but not Z-statistics? Also, I notice that the annotation is picking only one of the anatomical regions in which the cluster is located. Is it possible to tell all the anatomical regions that a label has? Thanks, Daniel -- Daniel Yang, Ph.D. Yale Child Study Center E-mail: daniel.yj.yang(a)yale.edu

Dear Freesurfer experts, I am running tracula v5.3.0 on OpenSuse. I successfully ra n freesurfer reconstruction and trac-all-prep. However, when I try to run trac-all -bedp -c dmrirc_file, I get the following message: .... 47 s lices processed 48 s lices processed 50 s lices processed 53 slices processed Queuing post processing stage sw/freesurfer/5.3.0/bin/bedpostx_mgh: line440: 8026 Terminated ${subjdir}.bedpostX/monitor I am not running bedpostx on a cluster but locally. Any suggestions why it might be terminated? Thank you, -- D.

Dear FreeSurfer experts, After running the following command: recon-all -autorecon2 -autorecon3 -subjid S08_FS I get the following error: /Volumes/FLYNN/ProjetPhonoBehavioralTMS/Freesurfer/S08_FS/mri \n mri_mask -T 5 brain.mgz brainmask.mgz brain.finalsurfs.mgz \n threshold mask volume at 5 ERROR: dimension mismatch between source and mask Darwin Isabelles-iMac.local 12.6.0 Darwin Kernel Version 12.6.0: Wed Mar 18 16:23:48 PDT 2015; root:xnu-2050.48.19~1/RELEASE_X86_64 x86_64 recon-all -s S08_FS exited with ERRORS at Mon Nov 9 18:56:20 EST 2015 I read in a post that it might be a problem with registration, so following a post found on the forum, I re-analyze this participant (from scratch) using: recon-all --autorecon1 -use-mritotal -subjid S08_FS then I ran recon-all -autorecon2 -autorecon3 -subjid S08_FS However, this did not solve the problem. Is there a workaround that I could use after the pial edits and running the -autorecon2 and 3? Thank you very much in advance, Isabelle

Two recons with different vertex coordinates
by Reza Rajimehr 09 Nov '15

09 Nov '15

Hi, We have run recon-all twice on a single subject, both times without any error. Using a functional localizer, we have made a surface-based label for an ROI (FFA) in the ventral temporal cortex of the inflated surface from the first recon. When we visualize the same label on the inflated surface of the second recon, the label shows up as scattered points in the lateral parietal cortex! Why do we see such a huge difference in the vertex coordinates across the two recons of a single subject? Reza
