[Freesurfer] can I apply freesurfer significant clusters as ROI in fMRI study?

2014-11-20 Thread chenchunhuichina
Dear freesurfer experts, I searched on the wiki but can not figure out how to solve this problem: I found some significant clusters on graymatter thickness, how can I use it as a ROI in my functional MRI study? I have both structure and function data of the same subjects, so I can either do it

Hi Martin, I appear to have run into an issue when processing longitudinal data with the -hippo-subfields command. I get the following error. I have run the process in the cross (independent) mode and it ran okay at each time point (I have two). Wrote out aseg_thresholded.mgz kvlMathematicalM

Hi Chunhui if you have the significant clusters as overlays in fsaverage you can load them in tksurfer and use the "custom fill" button to create ROIs from connected compontents that are above threshold, then go from there (e.g. mri_label2label to map them to individual subjects, etc...) che

Sorry, forgot to say that I tried the -long option for two time points without the -hippo-subields option and it completed without errors. Thanks again Erik From: freesurfer-boun...@nmr.mgh.harvard.edu [freesurfer-boun...@nmr.mgh.harvard.edu] on behalf of Erik O

Hi Erik, did you experience the same problem with any other cases? Also, do you think you could send us the log file [subjectdir]/scripts/hippo-subfields.log, as well as the contents of [subjectdir]/tmp/subrieldResults? Cheers, /Eugenio Juan Eugenio Iglesias Postdoctoral researcher BCBL www.jeig

Dear FreeSurfer experts, I get a new message when I use "mri_convert" command to convert dicom to mgz. I used to apply this command before and there was no problem. I wonder what is the reason that I get the new message. In addition, it does not create mgz file, and goes to infinite loop. *mri_c

Hi Tim can you elaborate what the issue is? If you have binary lesion maps inthe volume, can't you just sample those onto the surface and measure surface area directly? I think I am missing something Bruce On Wed, 19 Nov 2014, Timothy Meier wrote: Hello, I just wanted to repost this to se

Hi there, In my understanding, mris_convert does not change any information (vertices coordinates and triangles) during converting, right? However, I observed odd thing as bellow, Command I used:* mris_convert subjid/surf/lh.white subjid/surf/lh.white.stl* I convert the white surface to .stl for
