It is expecting a voxel shift map, which won't work with topup. One thing you can do is to do the preprocessing (motion correction, slice timing correction, topup) outside of fsfast, save the output as something like f.mypreproc.nii.gz, then specify -funcstem f.mypreproc when running mkanalysis-sess
