Error
by Weerasekera, Akila 23 Dec '20

23 Dec '20

Hello, I sent a few jobs to launchpad (FreeSurfer segmentation) and they exited with an exit=1, this is the error: "ERROR: Label FG1.mpm.vpnl does not exist in SUBJECTS_DIR fsaverage! The fsaverage link probably points to an older freesurfer version" I switched from Fs 6 to FS 7.1.1, how do I change the fsaverage link? Any help is appreciated.

External Email - Use Caution Dear Freesurfer experts, As indicated here https://secure-web.cisco.com/1U4b2EkUfPD8P1X6LdxE7H-WrQG5N2w5Lnh1FY6jUHMlzI… I am rerunning the code below to creare the file norm.mgz: mri_em_register -mask brain.mgz -p .5 nu.mgz \ $FREESURFER_HOME/average/RB40_talairach_2005-07-20.gca \ transforms/talairach.lta I got this error: == Number of threads available to mri_em_register for OpenMP = 1 == reading 1 input volumes... logging results to talairach.log reading '/opt/freesurfer/6.0/average/RB40_talairach_2005-07-20.gca'... GCAread(/opt/freesurfer/6.0/average/RB40_talairach_2005-07-20.gca): could not open file No such file or directory mri_em_register: could not open GCA /opt/freesurfer/6.0/average/RB40_talairach_2005-07-20.gca. No such file or directory This solution above does not work for me because the file : RB40_talairach_2005-07-20.gca does not exist in /opt/freesurfer/6.0/average I thought maybe the problem is that the file RB40_talairach_2005-07-20.gca is called now in a different way? Please could you tell me how the file “RB40_talairach_2005-07-20.gca” is called for Freesurfer v 6.0? there are two files in the folder “average” that terminate with .gca: RB_all_2016-05-10.vc700.gca or RB_all_withskull_2016-05-10.vc700.gca Thank you very much in advance Best regards Ileana Camerino PhD candidate Donders Institute for Brain, Cognition and Behaviour Centre for Cognition Spinozabuilding Room B02.25 Montessorilaan 3, 6525 HR Nijmegen The Netherlands Tel. +31-24 3612618

No extracerebral CSF in sGTM
by Julie Ottoy 23 Dec '20

23 Dec '20

External Email - Use Caution Dear Petsurfer team Does the sGTM PVC correct for the uptake in extra cerebral CSF? If not, how would this affect the reliability of the cortical PVC measures, considering the spill-out of grey matter uptake to csf is being ignored? Thank you! Best regards Julie

cluster size and FWER rough equivalence?
by Kayle Sawyer 23 Dec '20

23 Dec '20

External Email - Use Caution We are working on a manuscript revision for an fMRI project that was analyzed with FS-FAST 5.3 years ago. We used mri_glmfit, and then we ran mri_surfcluster (instead of mri_glmfit-sim) with a vertex-wise threshold of p<0.001 and a cluster threshold of 100mm^2. We had applied 8 mm smoothing at the group-level, and the voxel size was 3.125x3.125x5 (resampled to fsaverage surface and to MNI305). 1. One reviewer asked us to provide a rough estimate of the family-wise error rate (FWER) that a cluster threshold of 100mm^2 is equivalent to, or alternatively, to re-analyze everything with mri_glmfit-sim permutation. It would be simpler to provide the FWER estimate. To get the FWER estimate, we referred to Woo et al (2014). However, their simulations were for volume analyses, not surface analyses. What is the FWER (roughly) for a primary threshold of p<0.001 and cluster threshold of 100mm^2? (Obviously, we are hoping for a number less than 0.05.) 2. For the volume, we used mri_surfcluster with a primary (voxel-wise) threshold of 0.001 and a size threshold of 300mm^3. If I’m understanding correctly, Figure 2 from Woo et al. (2014) suggests a FWER p<0.05 might roughly correspond to a cluster size threshold of 200 to 985 voxels (1600 to 7880 mm^3), depending on intrinsic smoothness. That would likely put our threshold of 300mm^3 well above p<0.05. Is this correct? Thanks, -Kayle

Vertex-wise functional ROI extraction
by Sussman, Lauren 23 Dec '20

23 Dec '20

External Email - Use Caution Hello! I would like to extract functional data from a manually created label ROI on the surface on a vertex-wise basis. Funcroi-table-sess appears to only provide averaged values and I would like the value per vertex inside the ROI for the given contrasts. Is there a way to grab this data using Freesurfer? Thank you! Lauren
