Gang,
Thanks!! I did use -Rbuck. Where would this information be stored, and how do I extract this? The following is the command used:
3dREMLfit -matrix X.xmat.1D -input pb04.Imagination001.r01.scale+orig.HEAD \
-fout -tout -Rbuck stats.Imagination001_REML -Rvar stats.Imagination001_REMLvar \
-Rfitts fitts.Imagination001_REML -Rerrts errts.Imagination001_REML -verb $*
Many thanks again, and best wishes,
Ranjan
