@rtopfer I just tested this out, and was able to use the testing dataset that has a number of volume repetitions that differs from the original number. To confirm, the original error when usingMaRdI.resliceimg() still occurs. This is expected, right?

@evaalonsoortiz should work now? tbh the whole function seems way more complicated than it ought to be... i feel there must be a simpler built-in matlab function somewhere 🧐

Hmmm, still getting an error. I am using the EPI image in the sample dataset "34_ep2d_bold_realtime_zshim_UNSHIMMED_2" instead of a GRE for the resampling. The error I am getting now is slightly different:

Error using MaRdI/resliceimg (line 1283)
Dimensions of the arrays of extrapolation coordinate and the assigned extrapolation ROI mask must be identical

Error in realtime_zshim (line 310)
GzField.resliceimg( X,Y,Z, mask ) ; % reslice static b0 image

I think ANTs ResampleImage could replace this once the code is fully nifti-functional.
