Hi AFNI folks,

I discovered (I think) a small bug when using the 3dANOVA programs with niml surface files. The error comes at the end of the std output in cases where I've included a -bucket option for putting all calculated sub-bricks into one bucket. Here's the command I ran and the associated error:

Looks like the 3dbucket command has the standard AFNI '+orig.HEAD' appended to the 'niml.dset' files and, of course, can't find anything like that. As a result, no bucket is written and the 3drefit command fails, as well.

Thanks,
Adam
