3dQwarp Failing

I am trying to run 3dQwarp on denoised T1 images. The images were originally in .mnc format and I converted them to NIFTI using 3dcalc (-expr ‘a’ -prefix ‘name.nii’) and then ran them through an MRI denoising package in Matlab. When I use 3dQwarp to warp the to the MNI space, it fails. Crash log is below. Any idea what is going on?

Check that your volumes are defined properly in either AFNI or NIFTI format. Check origins and orientations with 3dinfo. Use the afni GUI to verify the two datasets display properly. You may want to use @Align_Centers to move the center of one dataset over the center of the template dataset.
