Excellent, one down.

3dmaskdump would do the trick, here is an example command from the demo script run_ROIdump in the bootcamp directory suma_demo/

3dmaskdump -mask lh.OccROIs.FULL.niml.dset \
-mrange 2 2 \
-index -noijk -o ALLv2b.ts.1D \
v2s.lh.TS.FULL.niml.dset

See 3dmaskdump -h_view for details. As usual, verify visually that what you get is what you were expecting, until you have a handle on how the command lines work.

cheers
