Re: [Freesurfer] Image acquisition in different head coils

Hi Carolina yes, that will most likely lead to bias. The 8 channel probably has significantly worse SNR over much of the brain. Sorry Bruce On Sat, 2 Nov 2013, carolina.mr wrote: Hello,   Is it possible to compare FreeSurfer segmentation of images with similar protocol but acquired in diff

[Freesurfer] Image acquisition in different head coils

Hello,   Is it possible to compare FreeSurfer segmentation of images with similar protocol but acquired in different head coils (8 channel x 32 channel)? What are the possible bias and problems?   Thank you, Carolina  ___ Freesurfer mailing list Freesurf

Re: [Freesurfer] How do you create labels from binary masks?

Hi Marcos, I don' t know if you are trying to the same as me, but I just divided the hippocampus with matlab and then treat each segment as an individual file, from lh_HPC.mgz to lh_head_HPC.mgz, lh_body_HPC.mgz and lh_tail_HPC.mgz. You can threshold those files and binarize, or you can leave their
