I don't know what you mean by 3D coordinates or a 1d array of corresponding phase values. In any case, use the mri.vol. This should be in voxel-for-voxel correspondence with your input data. doug Jason Connolly wrote: Dear freesurfer experts: I noticed that there are two 'vol' fields when I

[Freesurfer] two vol fields for retinotopic analysis?
