how would you handle checksums of conditional workflow surgeries inside niworkflows? don't they depend on the inputs?

@psadil - these are the occurrences i found. ``` $ grep -rn loadmat nipype nipype/algorithms/misc.py:358: in_dict = sio.loadmat(op.abspath(self.inputs.in_file)) nipype/algorithms/misc.py:397: in_dict = sio.loadmat(op.abspath(self.inputs.in_file)) nipype/algorithms/rapidart.py:756: spmmat = sio.loadmat(self.inputs.spm_mat_file, struct_as_record=False) nipype/interfaces/spm/model.py:287: spm =...

@oesteban - the new api we are working on basically has the following subclassing structure `Node -> Workflow`, so by definition a `Workflow` can be a `Node`. we have a...

@hstojic and @effigies - since this creates a patch without a broken test, it would be great to have a broken test as well. i just asked @hstojic to add...

@oesteban - i think any settings that are helpful would be nice. although ants folks thinks of ants as a framework and one may need to optimize settings for each...

@oesteban - this looks reasonable.

@salma1601 - one of the doctests needs to be updated with this: ` -1Dmatrix_save functional_allineated.aff12 `

@oesteban, @chrisfilo - we need to come up with a reasonable solution before this release. turns out the file is not created when the threshold does not result in any...
