Hi - yes, we expect in the next release to include the MNI<->Tal
conversion and Talairach (etc) labels into the FEAT output etc. You're
right, FSLView doesn't run under Sun - but if you have the files mounted
on a apple/linux/windows machine you can easily view them there with
FSLView.
Anyway - yes, your plan sounds like a fine approach....good luck! Don't
forget that img2imgcoord and img2talcoord are useful programs for this
kind of thing.
Cheers, Steve.
