It is the first frame. You'll have to get the average from the gtm.nii.gz file. You can do it easily enough in matlab with gtm = fast_vol2mat(MRIread('gtm.nii.gz')); % gtm will be a 4xNrois matrix mean(gtm) On 12/09/2016 03:21 AM, Donatas Sederevicius wrote: > > Hello FreeSurfer Developers,

You will need to create the yeo parcellation for each subject as well as run mris_anatomical_stats to create the stats file, then run aparcstats2table specifying the new stats file. Look in the recon-all.log file to see how to call mris_anatomical_stats On 12/14/2016 03:56 PM, Martin Juneja

Dear All, Our MPRAGE and T2 SPACE FLAIR sequences are acquired at times during two different scans, and the MPRAGE seq further gets reoriented in a pipeline upstream of the Freesurfer step. For best results, does the FLAIR volume have to be reoriented (and resliced) in a rigid registration to the

We are shooting for Wed Dec 21 for a final release of v6, so you may want to use that. If you run recon-all on a data set that has already been edited, it will use the edits you have (and will not delete them), so I recommend making a backup of your 5.1 analysis and then run 6.0 on it. On

Hi Allison, you have two options: 1. replace the mri_robust_register and mri_robust_template executables with newer ones (but who knows if flags changed, so this may not work directly, in that case also the call in recon-all may need to be adjusted). 2. better: simply run all bases with 5.3
