Re: [Freesurfer] freesurfer license on multi-user cluster (Bruce Fischl)
by Wang, Zheng 21 Aug '12

Hi, Bruce, I'm wondering where I can get this system-wide FreeSurfer 5.1 download? Also, is there any manual or instruction for installation on multi-user clusters? Thank you very much!

bbregister with PET data
by Marco Loggia, PhD 21 Aug '12

21 Aug '12

Hi Doug and Freesurfer team, I am trying to coregister some PET maps with their relative high resolution MEMPRAGE files. I was thinking that bbregister might be my best option but the results are still not satisfactory, likely due to the intrinsic features of my radioligand (the resulting maps are quite 'noisy' in terms of anatomical details). Do you have any suggestions on how to improve the results of bbregister (e.g., flags to use, or preprocessing steps prior to running bbregister)? - the PET map for one subject is here: /autofs/space/katahdin_005/users/marco/PBR28/data/PBR_CLBP001/PET/PBR_CLBP001_average8-28_BET_hdrOK.nii - my SUBJECTS_DIR is here /autofs/space/katahdin_005/users/marco/PBR28/data/ - The command I ran is: bbregister --init-fsl --mov PBR_CLBP001_average8-28_BET_hdrOK.nii --t2 --s PBR_CLBP001 --reg PET2brain.BB.reg --o PET2brain.BB.nii Thanks!

GCA file for non-human recon-all use
by Jeff Thompson 21 Aug '12

21 Aug '12

Hello, I have a few questions that I hope can be answered: Q1:How can '.label' files be turned into the necessary '.gca' file needed for the recon-all pipeline. Starting for the first step in auto-recon2.What else other than the '.label' files would be needed to create this '.gca' file? Q2: How to get the seg_edited.mgz file? I would want to use this file in the rebuild_gca_atas.csh script. Q3:Can the rebuild_gca_atlas.csh script be used to make a replacement for the RB_all_2008-03-26.gca file from the average folder? Q4:Is there a way to avoid needing the .gca file if cortical thickness measurements is the only goal?Or could there be a limited number of labels needed incorporated into the .gca file for this goal. Ex. Just Cerebral cortex ROI's. Thank you for any help, Jeff Thompson

mri_segstats error
by Blazey, Tyler 21 Aug '12

Hi, I recently installed the updated mri_segstats (ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_segstats.…) This seems to work fine for recalculating the supratentorial volume. However, it is causing my new recons to fail (see example error below). Any suggestions?

freesurfer license on multi-user cluster
by John Donners 21 Aug '12

21 Aug '12

Dear developers, I just installed freesurfer 5.1.0 system-wide on one of our clusters. All of our users can now access the software, although there is only one license key in the installation directory. Maybe you prefer that every user on our system uses their own license key for your usage statistics? An environment variable FREESURFER_LICENSE could maybe be used for this purpose? Or an additional check for a local license file ~/.freesurfer_license? With regards, John -- John Donners Consultant OSD SARA Science Park 140 1098 XG Amsterdam T +31 (0)20 592 3055 F +31 (0)20 668 3167 M +31 (0)6 1903 9023 E John.Donners(a)sara.nl www.sara.nl

QDEC's clusters and connectivity maps
by Antonella Kis 21 Aug '12

21 Aug '12

Dear FS team, I am trying to find what is the connection between white matter tracts with reduced FA and a number of cortical regions/clusters with significant reduction in cortical thickness from QDEC. Is there a way to overlap my cortical regions with reduced thickness more exactly the clusters from QDEC on the connectivity maps in FSL. How I create a mask of the QDEC clusters and used them in tractography? The tractography/ connectivity maps has been performed on the MNI standard space. Any suggestion will be greatly appreciated. Antonella
