Hello,

Firstly I add the phasediff and magnitude files to the fmaps in other imaging options, I select them both and add them together, there is a first and last magnitude images in the same magnitude.nii file and one phase diff files. Atleast theoretically both of them have the same size. Then, I add a few more steps to preprocessing, namely: "Creation of Voxel Displacement Maps for Susceptibility Distortion Correction" and "Susceptibility Distortion Creation using Voxel Displacement Maps" to the preprocessing pipelene. When I run preprocessing, I get the following error below. 

I also tried using a spm topup script to externally extract the VDM files but the error I get there too is similar. "Images don't have the same orientation and voxel size."

Any help would be appreciated, thanks!
