Hi, I'd like to map some foci from past studies onto the Colin surface. I've noticed that there seems to be 2 options for selecting co-ordinate type during this process;
1 - when loading the Colin spec file, there is the option of choosing the SPM99, SPM2, etc fidcucial surface. 2 - in the 'studies' tab of the 'map stereotaxic focus' dialog, it is possible to choose the stereotaxic space used in the study. Just want to check that I've got this right: If I chose the Colin fiducial to be SPM2, then that means the surface has been registered to SPM2 template space. If I want to map the focus of a study that used SPM99 space, will choosing SPM99 in the 'map stereotaxic focus' dialog automatically convert the coords so the focus appears in the (roughly) correct spot on the SPM2-space surface? If so,if a study has reported coords that have been transformed from MNI to talairach (e.g., using Matthew Brett's method), would choosing 'AFNI' in the 'map stereotaxic focus' dialog be the most appropriate? Finally, there are some studies that used SPM96. Does anyone know if there are large differences between SPM96 and SPM99 spaces, or indeed, between SPM99 and SPM2 spaces?
