QDEC bad fd number

04 Mar '14

Hi freesurfers, I get this error when I load qdec.table.dat. Is it something wrong or should I ignore it? Verifying subject data.sh: 1: Syntax error: Bad fd number ERROR: QdecProject::VerifySubjects: Couldn't find subject '6027' in SUBJECTS_DIR .sh: 1: Syntax error: Bad fd number ERROR: QdecProject::VerifySubjects: Couldn't find subject '6209' in SUBJECTS_DIR .sh: 1: Syntax error: Bad fd number ERROR: QdecProject::VerifySubjects: Couldn't find subject '6243' in SUBJECTS_DIR . . . ERROR: QdecProject::VerifySubjects: Couldn't find subject '6052' in SUBJECTS_DIR Too many subjects not found! Someone else complained about the same problem but there was no reply: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg08288.html My qdec.table looks like this: fsid diagnosis Cage 6027 ABN -1.39 6209 ABN 2.61 . .

Hi everybody, I'd like to know if it's possible and if yes how to add new paths to the tracula pathlist? Otherwise how can I add a new path after the entire trac-all process? Francesco Baldacchini

Compute DTI metrics in NAWM in Tracula
by Celine Louapre 04 Mar '14

04 Mar '14

Hi Anastasia and freesurfer experts, I am trying to get DTI values along the tracts as in the pathstatbyvoxel file, but excluding inflammatory WM lesions. I have masks of the WM lesions that I could apply on the DTI maps, but then how could I compute the DTI metrics along the tract with the exclusion of the lesion? (I guess the last step of trac-all -path could be applied to DTI maps that were masked by the lesions?) I would like to keep the advantage of having the DTI weighted metrics in particular. Thanks a lot for your help! Celine -- Celine Louapre, MD-PhD, Research Fellow at Massachusetts General Hospital Department of Radiology, MGH Building 149, Room 2301 13th Street Charlestown, MA 02129

error at spmregister
by Borzello, Mia 04 Mar '14

04 Mar '14

Hi Freesurfers, I get an error when using spmregister saying "Maximum variable size allowed by the program is exceeded"- is that a problem with the number of dicoms? I can attach a screenshot of the error if that helps. Thanks, Mia

Hi Freesurfers, I'm wondering if there is a way to set the contrast when in tkregister. When I compare the MR with the CT, I get the following image (attached)- is this a problem with the MR I initially chose to run the reconstruction on? Thanks, m
