Re: [Freesurfer] Variability in bedpostx output

Wow, that's interesting. In both cases it's called with the default settings, without specifying any special options on the command line. You could verify this by running the respective versions of bedpostx independently of tracula and looking at the outputs. Unless of course something has cha

Thank you Anastasia. Unfortunately, I posted the question to the FSL list first and after a few go-rounds with clarification and more info, they felt like it was potentially a problem of the calls to the bedposts command from within Freesurfer. Their final assessment was that there should be n

Hi Jeff - Questions about bedpostx output files are best addressed to the FSL list, as it's an FSL program that is not developped by us. The appropriate info to provide them is the FSL (rather than freesurfer) version numbers. a.y On Tue, 11 Feb 2014, jwa...@nmr.mgh.harvard.edu wrote: > Hell

Hi Leila, I just wanted to let you know that I took a look at the parcellation snap shots you sent along (the rostro-lateral views of the frontal cortex) using V3 and V4 and it seems from these that at least for the superior, and middle frontal gyri, the V4 image is indeed more accurate (i.e. foll

Hi Leila, Xiao Han's NeuroImage paper discusses thickness variability, and we've looked at parcellation variability in-house, but I don't think we've published on it. The V4 parcellation is should be a bit more accurate at the midline, but not substantially different. cheers, Bruce On Wed, 5
