Dear Nele,
There are two things going on here. The first one is about selecting all of the frames of the 4D file in the Normalise:write batch. One way to fix this is to do as Volkmar described, see also:
https://en.wikibooks.org/wiki/SPM/Working_with_4D_data
or to change your script to remove the ",1" at the end of the NIfTI filename:
matlabbatch{1}.spm.spatial.normalise.write.subj.resample = {'C:\......\rfunctional4D.nii'};
The second issue is that there is a bug in SPM given that, even if you didn't select your data the way it should have been, a NIfTI file with an invalid header was created. I hope to fix it shortly.
Best regards,
Guillaume.

in SPM the file selector will by default only list the 1st frame of
each dataset. To view/select all 250 frames, enter 1:250 into the
frames textbox below the file list.
Hope this helps,
Volkmar
