Thank you, Bruce

If possible, I would like to transform an individual coordinate (x,y,z) from FreeSurfer space to the native space.

Hi Yiyu

Can you clarify what you are trying to do? Take an individual coordinate or list of them and transform them? Or transform an entire volume? And what kind of coordinates do you want at the end? Voxel indices? RAS?

Cheers

Bruce

Dear FreeSurfer experts:

I wonder if there is a command to convert coordinates from FreeSurfer space to the native space.

Thanks in advance !

Yiyu
