Re: [Freesurfer] fsaverage mesh has duplicate pt
by Xuelong Zhao 10 Apr '14

10 Apr '14

Hi, I loaded the lh.orig cortex for fsaverage into Matlab. My colleague and I found that it actually has a duplicate point. The index of the duplicate points are: 1 40970 I checked that both have the same vertices coordinates: -36.7233 -18.4039 64.3611 I'm not sure if this is intentional or not but wanted to draw the freesurfer community's attention to this in case it is a bug. Also, I believe a similar issue is present for fsaverage's lh.pial and rh.orig (I haven't checked other cortices). Regards, AZ

Freeview, fsaverage_sym & aparc.annot
by Peggy Skelly 09 Apr '14

09 Apr '14

Hi Freesurfer experts, I'm trying to view aparc.annot on a fsaverage_sym surface. I can load aparc.a2009a.annot with freeview -f $SUBJECTS_DIR/fsaverage_sym/surf/lh.pial:annot=aparc.a2009s.annot but attempting freeview -f $SUBJECTS_DIR/fsaverage_sym/surf/lh.pial:annot=aparc.annot results in freeview crashing. The command window output is in the attached text file. (Freeview 1.0 May 14, 2013; Mac OS 10.9.2) Thanks, Peggy

Create a label from a binary mask
by Cherisse Onuigbo 09 Apr '14

09 Apr '14

Hello I was wondering how to create a label from a binary mask. I created a mask and then normalized it to the template space. When I tried to use mri_cor2vol, all the vertex numbers come out as -1. I understand that the vertex numbers should come out as -1, but when I entered the coordinates in the display function in spm, it was not in the region. Thank you, Cherisse

Questions about byvoxel statistics from Tracula
by Emilie Poirion 09 Apr '14

09 Apr '14

Hello I'm using Tracula to analyse our DWI-images. Freesurfer reconstructions of the corresponding T1-images have been perfomed before. Respectively, the version used are 1.53 and 5.3. The Tracula process works fine and I have extracted the statistics for all tracts. About this statistics, I wanted to know what is the difference between FA and FA_Avg ? An other question about the values extracted is about the coordinates in the file "byvoxel.txt". Are they correspind with the coordinates of the voxel in the dtifit image were the values were extracted? The last question, can we extracted the same by tract statistics from an other image like a PET registered to the DWI with your code? Thanks for your answer -- Emilie Poirion Master 1 Informatique Industrielle et Imagerie Industrielle Université Pierre et Marie Curie (Paris 6)

Hi! I was wondering whether there is code available to quickly read cluster summary files into Matlab? I need access to the cluster-wise p-values. Thank you very much! Caspar
