Rick,

The problem seems to be that afni thinks these subjects only have briks from 0-67 in the zregression bucket datasets. However, opening them in afni (as also confirmed by 3dinfo) indicates that each has buckets numbered from 0 -69! So I get this output:

before I stopped it.

What gives? Could I upload one of these bucket datasets to afni site for examination?
