good. that is what we thought/assumed... and that (alignment in physical
space) means that having intermediate matrix of voxels to project to
should not have an effect (besides possible quantization/dequantization
into/from voxels), that is why we were surprised with the results

tested... script called reproduce2.sh from the same
http://www.onerussian.com/Linux/bugs/ants.2steps/
produced result mni2bold-2-epi.nii.gz  looks the same as previous
"incorrect" mni2bold-2.nii.gz, so issue does still exist.

if you run reproduce.sh, do you experience the same issue with your
version of ants?

I indeed could... script  reproduce3.sh at the same location -- the same
effect!
