Hmmm, that does not help.
If you start AFNI, open in the first viewer dataset SW_SUMA_SurfVol_Alnd_Exp1 and in the second viewer SW_volume_orth+orig are the two volumes aligned ?
You can determine that by locking the cross hair in the two viewers together. If the two data sets are not aligned then 3dTagalin might be the problem. Otherwise the problem is with SUMA and in that case you'll have to send me the data.
One last thing, can you also send me the output of SUMA as it is launching?
