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.

TRACULA preprocessing error, FreeSurfer 5.2.0
by McGinnity, Colm 16 May '14

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

Problems with tkmedit
by Esteve Cervantes Martin 15 May '14

15 May '14

Hi, I'm Esteve Cervantes an student from UPC. I'm trying to install Freesurferfrom the source and I'm having some problems with tkmedit. I previously had some problems with recon-all because I got segmentation faults. After installing the mni.srcbuilt.tgz from source and some fixes it runs ok. But when I wanted to run tkmedit to view my volumes I got only one window with the picture, but a blank window for the tools. Then I tried to install the tcltkticblt-8.4.6.tgz and after building again freesrufer, now I get nothing. The output is: ecervantes@v3:~/opt/freesurfer1/tktools>> vglrun tkmedit 002_S_0295 brainmask.mgz -surfs [VGL] NOTICE: Automatically setting VGL_CLIENT environment variable to [VGL] 192.168.1.31, the IP address of your SSh client.

Converting pial surface: 100% done. ecervantes@v3:~/opt/freesurfer1/tktools>> It starts and sudenly ends without showing any window... I'm out of ideas any help will be appreciated. Thank you, Esteve

BrainMask Edits
by David Tate 15 May '14

15 May '14

Question regarding the use of skull stripping errors. I am wondering if it is possible to correct (use the -wsthresh or -gcut) in longitudinal processed data or would these types of edits be required in the earlier processing steps (initial FreeSurfer recon-all)? Thanks in advance for any help with this. David F. Tate, Ph.D.
