Dear list,

I'm using the MNE Coregistration GUI tool to obtain the transformation
matrix.

I'm not able to figure out what co-ordinate system the scalp (shown in GUI)
is in and which MRI volume it is directly related to - /mri/T1.mgz or
/mri/orig/001.mgz ?

Thanks,

hi Kousik,

I'm using the MNE Coregistration GUI tool to obtain the transformation

I suppose it's in Freesurfer surface RAS.

is in and which MRI volume it is directly related to - /mri/T1.mgz or
/mri/orig/001.mgz ?

it should be using T1.mgz
