Hello All,

I thought this issue would be straight forward but I seemed to have run into some issues. I ultimately have two 3d data sets that I want to merge using 'to3d'. They are nifti file formats and, verified with '3dinfo', one is oblique and the other isn't. They both are the same matrix sizes. I'd like register the oblique data set to the cardinal, or non-oblique set. I thought using 3dWarp with '-oblique2card obliqueset.nii' and '-gridset parentcardset.niii' would be the solution but the resulting BrIk after trying to combine them with 'to3d' is all skewed in a very strange and unexplainable way. Is there anything that I seem to be missing or misunderstanding about this? Thank you always for all y'all's help.

Cheers
