Have you made sure that you have read permission to open those files? What is the output of `ls -l asta.mgh`? And asta.nii doesn’t seem to be a file in your working directory.

Best,

Andrew

        External Email - Use Caution        

Dear List, 

I have installed the ubuntu version of freesurfer (creating the VM as in the tutorial)

I would like to run the following command:

mri_convert -c -oc 0 0 0 asta.mgh orig.mgz

I always get the error in the screen shot. Can someone help me?

also using asta.nii format
