Dear FreeSurfer,

I have a problem when I use mris_anatomical_stats. It gives me an error saying that it couldn't read the input volume which is the wm.mgz file.
would you please help me how I should fix this problem?

mris_anatomical_stats -a label/lh.aparc.annot -b 60_AV rh

computing statistics for each annotation in label/lh.aparc.annot.

reading volume /Users/davidemomi/Downloads/Broad_60_AV//60_AV/mri/wm.mgz...

mghRead(/Users/davidemomi/Downloads/Broad_60_AV//60_AV/mri/wm.mgz, -1): could not open file

mris_anatomical_stats: could not read input volume /Users/davidemomi/Downloads/Broad_60_AV//60_AV/mri/wm.mgz

Thanks in advance
