Great, if you can add some choice to run these subjects in parallelized, like a flag '-n_threads', this will be perfect considering the time-consuming problem, good job! Good day De : freesurfer-boun...@nmr.mgh.harvard.edu de la part de Yendiki, Anastasia E

Hi Anand have you run recon-all yet? Ideally you would give it a non-enhanced 3D T1 (like an mprage). We don't segment vessels though, for that you will need to use some other software. cheers Bruce On Mon, 19 Dec 2016, anand iyer wrote: > Hi > Could you please help with this? > > I am ab

[Freesurfer] Ynt: Neighborhood of a vertex

2016-12-19 Thread Onur Uğurlu
Hi Bruce, Thank you so much for the answer. I have used "read_surf.m" function and got the list of vertex locations and a list of faces. However, the list contains 107106 vertices whereas the lh.thickness.asc file contains 118603 vertices. How can I match the thickness values which are inlh.

that shouldn't be the case. Run mris_info or mris_euler_number on your input surface. Can you load the thickness as a surface overlay? It may be that you regenerated surface and not the htickness, or visa-versa. Which surface are you using? On Mon, 19 Dec 2016, Onur Uğurlu wrote: Hi Bruce,

No - there is no relation between B0 field inhomogeneities (measured by a field map) and b=0 volumes. The capital B refers to the magnetic field in the scanner, the small b is the b-value (diffusion weighting). From: freesurfer-boun...@nmr.mgh.harvard.edu [frees
