Hi Emma

can you run mri_info on the .mgh and .nii.gz volumes and send us the output? Is the sig.mgh a surface overlay? If so, you can't visualize it directly, you have to overlay it on a surface (in either .mgh or .nii.gz foramt)

Hi!

I’m trying to convert my sig.mgh output from GLM into a .nii file using mri_convert, and when I load the resulting volume in freeview this is what I see.

The command I’m using is: mri_convert —in-type mgh —out_type nii.gz —out_orientation RAS /(root to sig.mgh file)/sig.mgh /(root to output file)/sig.nii.gz,

Is there something I should be doing differently?

Many thanks,

Emma
