[Freesurfer] QA tools

2018-03-01 Thread Micah Rhodes
Dear Freesurfer list, As I have used the QA tools on a couple recon-all jobs, I have run into an error when running recon_checker QA tools. The QA tools are not able to read many of the output files from recon-all, in the "label" directory. As I look back into the label directory, this is because

Hi Colleen can you upload a sample subject? Otherwise there is really no way for us to judge. cheers Bruce On Thu, 1 Mar 2018, C.P.E. Rollins wrote: > Hi Freesurfer developers, > > I've processed my sample of T1 scans through recon-all and have > corrected the pial and WM surfaces. The surface

Hi Idil we keep track of different kinds of RAS coordinates, which may not be the same (surface ras, scanner ras, etc...). cheers Bruce On Thu, 1 Mar 2018, Yagmur Ozdemir 19 wrote: > Hello FS experts, > > I am wondering if anyone knows why the same vertices' coordinates are shown > slightly d

[Freesurfer] Hippocampal subfields {Disarmed}

2018-03-01 Thread 郑凤莲
Hi professors, I ran the segmentation of hippocampus in Freesurfer dev version. The left or right whole volume isn't equal to the sum of 12 subfields. But it is equal to the sum of the volume of tail, whole head and body. Why? I am looking forward to your reply. Thank you very much. Sincerely,

Hi Freesurfer developers, I've processed my sample of T1 scans through recon-all and have corrected the pial and WM surfaces. The surfaces look mostly good, though when I checked the aseg segmentations they are pretty poor and there is huge variability in the volumes I get from asegstats2table

[Freesurfer] tksurfer/freeview vertex coordinates difference?

2018-03-01 Thread Yagmur Ozdemir 19
Hello FS experts, I am wondering if anyone knows why the same vertices' coordinates are shown slightly different when opened in freesurfer and tksurfer. I was checking some annotation files for each subject across the two on inflated surface, and noticed slight coordinate differences in RAS. ex
