5 years ago To my knowledge, myCinterp does linear interpolation. spm_bsplinc does spline interpolation, which is non-linear (piece-wise polynomial). Depending on the data being interpolated, the results could be very similar or not. I would guess that they would be similar under most typical MRI-related data sets (e.g., time series or anatomical images). So if they are dramatically different there might be something wrong with the computation.

Hi experts,
Do you know the core difference between the myCinterp3 and spm_bsplinc interpolation function?
As far as I understand, I think they are just different in the way of approximating the point for interpolation, so they should provide interpolated images quite the same.
However, when I put the same input data (of course, they are formatted to fit each function), I got totally different interpolated results.
Could anyone point me out where am I wrong or misunderstood? Any offer you have would be highly appreciated.
Best, Soan
