Error in Mrtrix3's DWIPreproc

[GalKepler]

Summary

The _list_outputs method of DWIPreproc tries to set up an input called "export_grad_mrtrix", which should be "out_grad_mrtrix", causing it to fail.

Actual behavior

AttributeError: 'DWIPreprocInputSpec' object has no attribute 'export_grad_mrtrix'

Expected behavior

No AttributeError raising when running DWIPreproc...

How to replicate the behavior

from nipype.interfaces import mrtrix3 as mrt

dwipreproc = mrt.DWIPreproc(rpe_options="pair", align_seepi=True,)
dwipreproc.inputs.pe_dir = "j-"
dwipreproc.inputs.in_epi = "path_to_epi"
dwipreproc.inputs.dwi_file = "path_to_dwi"
dwipreproc.run()
