Hi there,
I’ve a dataset with 30 subjects and want to run some nipype-workflows. My problem is that some of my subjects are missing masks. Is there a way to avoid running some nodes if their input is empty - e.G. some kind of if-node?
My first attempt was to use MapNode but this works only if I have at least one or more files. If my DataGrabber cannot provide any mask the whole Workflow interrupts.
Thanks for any suggestions.
