Try:

mri_convert -ot mgz fred+orig.BRIK fred_surf/mri/orig.mgz

Note the addition of .mgz to orig.mgz, and the flag '-ot mgz', which specifies output type.

Hi there,

I'm starting off with an AFNI dataset (e.g., fred+orig.BRIK) and I want to convert this file to FreeSurfer's .mgz format. When I run the command "mri_convert fred+orig.BRIK fred_surf/mri/orig", I end up with 256 .COR files. How do I get .mgz files instead? Do I need to add something to the command line? I've checked mri_convert's help manual but I still can't figure out how to do this.

Hi, I was hoping to combine results for several subjects in a group analysis, but the paradigms vary slightly between subjects (specifically, one scanning session included 28 conditions, and the others only 14 conditions.) Is there a way to just look at the first 14 conditions for all subjects? In the typical group processing stream, an error results from the difference in the number of conditions. Do I need to just truncate the paradigm files, or would that upset the statistical maps? Thanks for the input, Margo
