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
