Hi, Lz-
Indeed, I haven't been able to get to this yet. In large part, because it would involve several other softwares that I am not familiar with. So, if you have done the hard work and know the changes that should be made, then that should speed things up.
Are you saying that the only change needed is that the voxel_order header field needs to use the opposite of AFNI's voxel order definition? That is, if
3dinfo -orient DSET
returns "RAI" or "IPL", you want voxel_order to be "LPS" or "SAR", respectively?
Is that the only change necessary for compatability, then?
