Contrast vector in Qdec terminal and DOSS vs DODS
by Santosh Yadav 19 May '14

19 May '14

Dear FS Experts, I am asking same question again since did not get any reply. I processed my data with FS 5.3 version and running analysis in Qedc GUI with DODS that include 2 groups (control and heart Failure). I want to see the cortical thickness difference between these 2 groups, with age and gender as a covariate. In Qdec GUI, model factors have three options that include the fixed factor, continuous factor (covariate) and nuisance variable. So group (control and heart failure) belongs to fixed factor while age and gender belongs to both continuous factor and nuisance variable. When I am running this analysis in Qdec by selecting the model that include only group the contrast vector in the Qdec terminal is 1, -1, and I believe its fine. But when I am designing the model that includes age and gender as a nuisance factor, the contrast vector showing 1, -1, 0, 0, 0, 0, on the Qdec terminal. So my question is why we have two extra 0, 0 in contrast vector, as per my understanding it should be 1, -1, 0, 0, please explain. I also need to run it with DOSS. Would you please advise how to run the same analysis with DOSS from terminal and if it is possible to look at the results in QDEC Display again. Another question: When I finished the analysis in Qdec and got the state data tables, that have 18 files, with volume, area, curv and thickness from both left and right sides. I am interested in cortical thickness and it's have four files with left and right with two versions. for example for left side one is lh.aparc.a2009s and one is lh.aparc. I am not sure which file should I used for the analysis. I believe for left side qdec is using lh.aparc, Is I am right? With Regards, Santosh K.

Rotated structurals
by Tudor Popescu 18 May '14

Hi everyone Are structurals that come out of the scanner somewhat rotated (a few degrees, but still visible, example - attached) processed normally by recon-all, or do they first have to be manually corrected (rotated)? Thanks! Tudor

mri_convert frame error in tracula
by Pedro Rosa 16 May '14

16 May '14

Dear All, As suggest, I am reposting a previous question. I am trying to run a single subject in TRACULA (trac-all -corr -c config), 148, for who there is a folder ‘1482’ with all DWI DICOMs and a folder ‘ESNA148’ with the recon-all processing (Freesurfer 5.3). Also in $SUBJECTS_DIR there is bval.bval and bvec.bvec. I attached the trac-all.log that comes with the following error: ERROR: fMRIframe: frame >= frames Can anyone help me? Thank you in advance! Regards, Pedro Rosa.

Dear Experts, I am very new to TRACULA, I apologise for what is probably a silly question. I've got the following error on running trac-all -prep (FreeSurfer 5.2.0): awk: cmd. line:1: fatal: cannot open file `0' for reading (No such file or directory) mri_concat --i /home/k1193186/FreeSurfer/TRACULA/ROLAND03A/dmri/dwi_frame.nii.gz --mean --o /home/k1193186/ FreeSurfer/TRACULA/ROLAND03A/dmri/lowb.nii.gz niiRead(): error opening file /home/k1193186/ FreeSurfer/TRACULA/ROLAND03A/dmri/dwi_frame.nii.gz ninputs = 1 Checking inputs ERROR: reading /home/k1193186/FreeSurfer/TRACULA/ROLAND03A/dmri/dwi_frame.nii.gz Can anyone tell me what this means and how to fix this, please? I'm guessing I've set up my configuration wrong or have the files in the wrong place? Many thanks! Best wishes, Colm. King's College London

Longitudinal Error: long_mris_slopes
by Jennifer Addicks 15 May '14

15 May '14

Hello, I recently installed FreeSurfer v5.3 on a Mac OS X 10.9.2. I am trying to run a longitudinal analysis (longitudinal two-stage model) on my data (26 participants, 2 time points each) which was processed (cross-sectionally and longitudinally) using a previous version of FreeSurfer (v4.5). When running the long_mris_slopes command: long_MRIS_slopes --qdec $SUBJECTS_DIR/qdec/long.qdec.table.dat --meas thickness --hemi lh --do-avg --do-rate --do-pc1 --do-spc --do-stack --do-label --time years --qcache fsaverage --sd $SUBJECTS_DIR I get the following error message {CED01 is one of my fsid-base names}: Traceback (most recent call last): File "/Applications/freesurfer/bin/long_MRIS_slopes", line 862, in <module> dirname = tempfile.mkdtemp('',prefix,'') File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/tempfile.py", line 329, in mkdtemp _os.mkdir(file, 0700) OSError: [Errno 13] Permission denied: './tmp-CED01_lh_thickness_34xA_9' Any suggestions? Sincerely, Jennifer

Dear Bruce, Is there a file generated by freesurfer which stores the subcortical segmentations together with the information of partial volume estimates? Thanks, Gabor
