Re: [Freesurfer] converting vertex numbers in .label files to R, A, S coordinates
Thank you very much for this information!! Best, Li On Jul 24, 2017, at 4:06 PM, Douglas Greve mailto:gr...@nmr.mgh.harvard.edu>> wrote: Try using mri_label2label with the --paint option. I think the vertex numbers need to be -1 (not random numbers). You will also need to convert the RAS to "tkregisterRAS", one of our internal coordinate systems. See https://surfer.nmr.mgh.harvard.edu/fswiki/CoordinateSystems, you'll need to do the inverse of case #1.

[Freesurfer] converting vertex numbers in .label files to R, A, S coordinates
Dear Freesurfer experts, My question concerns the .label files and the correspondence between the vertex numbers (in the first column) and the R,A,S coordinates.

[Freesurfer] mkbrainmask-sess: couldn't find register.dof6.lta
Dear freesurfer developers, I’d like to ask about an error I encountered in Freesurfer v6.0 with mkbrainmask-sess. I am using macOS Sierra. Here is the error: error:"ERROR: cannot find /Users/lguo15/Documents/MATLAB/fMRI_P3/Fisch_P3_01/bold/register.dof6.lta, you might need to run register-sess” The error goes away if I run register-sess before mkbrainmask-sess. However, my lab mates use v5.3 and ran the exact same preprocess pipeline without this error. The order for them is mkbrainmask-sess first and register-sess later. I’d like to ask whether it is true that maybe in v6.0 mkbrainmask-sess now depends on register-sess to generate the register.dof6.lta file? Or how should I interpret this? Does running registration and masks have some fixed order at all or it doesn’t matter?
