Dear FreeSurfer support,

I am a new user of the Freesurfer program and attempted to install everything this morning on my Mac OSx 10.11.6 (El Capitan). To preface everything, I updated my XQuartz program before installing, and I do not have Matlab on this computer and understand that I can’t use the fMRI functionality without this, but this is not my goal.

The installation appeared to go as planned, but when I went to test the installation with the commands:

$> <source_freesurfer>

$> freeview -v $SUBJECTS_DIR/bert/mri/brainmask.mgz -v $SUBJECTS_DIR/bert/mri/aseg.mgz:colormap=lut:opacity=0.2 -f $SUBJECTS_DIR/bert/surf/lh.white:edgecolor=yellow -f $SUBJECTS_DIR/bert/surf/rh.white:edgecolor=yellow -f $SUBJECTS_DIR/bert/surf/lh.pial:annot=aparc:edgecolor=red -f $SUBJECTS_DIR/bert/surf/rh.pial:annot=aparc:edgecolor=red

I received the following error:

-bash: $: command not found

I was not able to decipher this error with The Google, so I am hoping that you can help.

Thank you so much for your time!

Best Wishes,

Allie
