Sorry,

I do not seem to see the light.

I have a point in volume index coordinates [128.9 172 62.9 1] and need to obtain the surface/vertex RAS coordinates (not volume RAS).

 

matlab path

 /usr/local/freesurfer/subjects/subjid/mri

if I type

tkrRAS = Torig*[128.9 172 62.9 1]'

 

it tells me Torig undefined function or variable

 

If I try to define it with Torig: mri_info --vox2ras-tkr orig.mgz, it does not recognize mri_info

 

 

Nothing happens if I work from the freesurfer command window:

 

I know this is boringly basic but I am stuck, please advise.

 

 

Octavian
