Re: [Freesurfer] ASCII to MGH

If you have matlab, the easiest thing may be to load the ascii into matlab, then use MRIwrite.m to save it out. To make it easier, use mri_convert to convert the lh.thickness to mgh format, the use MRIread.m to load in the lh.thickness. The data are stored in the .vol field of the struct. Then just replace the .vol data with your ascii data and use MRIwrite to save it

Hello-

I know how to use mri_convert and mris_convert to obtain ascii files of thickness values that I can read into stats software, but I'm having trouble going the other direction. Is there a good way to convert ascii lists of vertex values into mgh files so I can view them as overlays or utilize commands like mri_surfcluster?

Thanks, Jim
