Re: [Freesurfer] Missing Control Points and QATools

Hi Matt I'm sorry to hear it. I've never heard of anything of ours deleting the control.dat unless you run recon-all with the appropriate -clean switch. I don't know an easy way to recover them. Do you need them back? You could do something like copy the subject, run the intensity

Re: [Freesurfer] dwi.ecclog file

Hi Loic - The command that computes the motion measures is dmri_motion, and it can take either the eddy_correct or eddy format as input. The former format contains affine registration matrices with respect to the reference frame (which usually is the first b=0). The latter format contains the

[Freesurfer] dwi.ecclog file

Hello, I have several questions regarding the dwi.ecclog file data from Tracula, using the FreeSurfer version V6.0.0. 1) Does Tracula still use eddy_correct from FSL, or was it updated with the new eddy function from FSL? 2) Are the values for each slice of dwi.ecclog relative to the first

Re: [Freesurfer] tractstats2table - all tracts for multiple subjects

Hi Jim - You can use the --load-pathstats-from-file option, as in the tutorial, to pass a text file that contains the paths to all the stats files that you want to include in the table. These can be from multiple subjects and/or tracts. http://freesurfer.net/fswiki/FsTutorial/TraculaStatistics

Hello Aaron, The build timestamp from the output below shows mri_convert is from 8/2014. When I look at the build timestamp on our stable 5.3 version of mri_convert I see it is from 5/2013. So the version that you listed is about 1 year newer than the 5.3 release I can see. It is possible

Hello Aaron, You could check to see if the CentOS 7 system is using disk encryption, e.g., if the following command return 1, then it would mean encryption is in use (which can be an issue with FreeSurfer). $ cat /proc/sys/crypto/fips_enabled If it returns zero, it could be an issue with a
