License invalid for Development Version
by Jeurissen Ben 05 Apr '16

05 Apr '16

Dear Freesurfer experts, I am affected by the PERL incompatibility described in https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2016-January/043504.… . To get around this issue, I switched to the newest development version as suggested in that post. However, my license file (which worked fine with the stable version) is not recognised: "ERROR: Invalid FreeSurfer license key found in license file /home/ben/freesurfer/license.txt” Do I need a special license for the development version? How can I obtain it? Cheers, Ben - Ben Jeurissen, Ph.D. Post-doctoral researcher Vision Lab, Dept. of Physics University of Antwerp Universiteitsplein 1, N.1.18 B-2610 Wilrijk, Belgium Phone: +32 3 265 24 77 Email: ben.jeurissen(a)uantwerpen.be<mailto:ben.jeurissen@uantwerpen.be> Url: http://visielab.uantwerpen.be/people/ben-jeurissen<https://mail.uantwerpen.be/owa/redir.aspx?SURL=iz3BHzAIEzF8TwCIE-FGWB58qJgP…>

Tracula problems (creating symbolic link)
by Efrat Kliper 05 Apr '16

05 Apr '16

Dear Freesurfer experts, I upgraded to Freesurfer 5.3 from Freesurfer 5.1 (all of the preprocessing has already been completed in Freesurfer 5.1) in order to run some new functions of Tracula (I have also installed the latest Tracula update (tracula.update.centos4_x86_64.5.3.2014_05_26). I am using: FREESURFER_HOME: /usr/local/freesurfer Build stamp: freesurfer-Linux-centos4_x86_64-stable-pub-v5.3.0 RedHat release: CentOS release 5.3 (Final) Kernel info: Linux 2.6.18-128.1.6.el5 x86_64 I encountered two problems: 1.

Structural resolution and longitudinal processing
by Angstadt, Mike 04 Apr '16

04 Apr '16

We have a large number of scans that have been processed through the standard cross-sectional stream. Subjects have a number of repeated scans, so we now want to take advantage of the longitudinal stream. When first beginning to run subjects through longitudinal template creation, we noticed a warning message in some cases in the log: ******************************************************************************* WARNING: Image geometries differ across time, maybe due to aquisition changes? This can potentially bias a longitudinal study! Will continue in 10s. ******************************************************************************* Looking into it, there does indeed appear to have been a change in the reconstruction stream that led to images at different times during the study to have slightly different voxel dimensions, changing from 1x1x1.2 to 1.01x1.01x1.2mm voxels. Our question is if there is some way to fix this prior to starting the longitudinal stream but without having to redo the original cross-sectional processing and editing that has been completed? -- Mike Angstadt Research Computer Specialist / PANLab Lab Manager Department of Psychiatry / University of Michigan (734) 936-8229 ********************************************************** Electronic Mail is not secure, may not be read every day, and should not be used for urgent or sensitive issues

Mismatch in dimensions using mri_label2vol
by Afzal, Afsana 01 Apr '16

01 Apr '16

Hi, I'm using mri_label2vol with the parameters below but the output .nii volume has the shape 163842x1x1 while the input volume is 27307x1x6. This dimension mismatch is causing issues in our gPPI pipeline. How can I generate a .nii output file with the 27307x1x6 dimension? mri_label2vol --temp fmcpr.sm4.fsaverage.lh.b0dc.nii (output file generated from preproc step) --label label_name.label --o label_name.nii --identity Thanks, Afsana ______________________________ Afsana Afzal Clinical Research Coordinator Massachusetts General Hospital Division of Neurotherapeutics Department of Psychiatry: Neurosciences 149 13th St, Room 2612 Charlestown, MA 02129 Phone: 617-643-5129 Fax: 617-726-4078

Longitudinal TRACULA - Error in path reconstruction
by Emad Ahmadi 01 Apr '16

01 Apr '16

Hi Anastasia, I hope you’re enjoying your evening! I’m doing longitudinal TRACULA analysis on two subjects, each having two time points. I have already taken the steps of longitudinal recon-all and trac-all -prep & -bedp. Now I’m trying to do trac-all -path, but it gives me an error that I cannot recognize. I would greatly appreciate your help. I’ve attached the log files and the config file. Thank you so much, Emad Emad Ahmadi, MD ----------------------------------------------- Research Fellow in Radiology Massachusetts General Hospital Harvard Medical School 25 New Chardon Street, Suite 400 Boston, MA 02114 Tel: 617 726 5237 Email: emad(a)nmr.mgh.harvard.edu
