[Freesurfer] comparison between two hemisphere in single

2016-02-20 Thread Ashkan Faghiri
Thank you doug for you answer. So now I have two other question. 1- how can I check the inter hemisphere registration quality? e.g. can I check if the parcellation for the two hemisphere are matched well? or there is other ways? 2- how can I correct for multiple correction for single subject? cal

[Freesurfer] 1.5T GE dicom images into FreeSurfer

2016-02-20 Thread pda...@westol.com
Hi, We would like to process 1.5 T GE dicom scans for over 200 individuals. It is unclear how to import these into FreeSurfer and process in batch. Each subject folder consists of several subfolders. Each subfolder consists of all the images of a single pulse sequence, e.g. sagittal spgr, axia

Hi Marta A 2D surface (like the cortical white or pial models) has two principal curvatures at each point - one in the direction of maximum curvature and one in the direction of minimum curvature - typically denoted k1 and k2. The mean curvature is the average of these H=(k1+k2)/2 and the Gaus

Hi Corinna can you send us your full command line? Sounds like you are using a surface overlay as the cover_seg parameter instead of a volume one. Try running mri_info on it to make sure it is a volume (i.e. 256x256x256). If not, you will need to sample it into the volume with mri_surf2vol tha

[Freesurfer] Building from source #2 -- dynamic binding

2016-02-20 Thread Yaroslav Halchenko
Hi again, While our "building from source" discussion is "hot" I wondered to ask if there was an attempt or may be plans for to switch to using dynamic linking (and collect functionality within a few internal libraries) instead of static duplication of binary code across binaries. At some point M

hmmm, the only thing that worries me about dynamic linking is that it will add variability to the outputs. Zeke has spent endless amounts of time tracking down e.g. mac vs. pc differences in math libs and such. Won't dynamic linking just make that a much more prevalent problem? Bruce On Sat,
