Summary
#1949 introduced ImageFileSPM that gives a nice error message, when input file is nii.gz, but Realign gives still the old error message " the path '/data/ds000114/sub-03/func/sub-03_task-fingerfootlips_bold.nii.gz' does not exist."
How to replicate the behavior
Compare these two codes:
from nipype.interfaces.spm import Smooth
smooth = Smooth(in_files='/existing/file.nii.gz')
smooth.run()
and
from nipype.interfaces.spm import Realign
realign = Realign(in_files='/existing/file.nii.gz')
realign.run()
Actual behavior
The first code gives a nice error:
TraitError: /existing/file.nii.gz is not included in allowed types: .img, .nii, .hdr
the second gives:
TraitError: Each element of the 'in_files' trait of a RealignInputSpec instance must be a list of items which are an existing file name or an existing file name, but a value of '/existing/file.nii.gz' <class 'str'> was specified.
Expected behavior
Both examples should give the same error.
