Taliairach coordinates can be converted to MNI space and subsequently a sphere mask can be made in FSL but it would be preferable to convert to MNI space an actual Talairach space mask made for the structure in question (a thalamic nucleus); the thalamic nucleus in question is not currently available in MNI space.
