### Summary I'm not sure why others wouldn't have caught this one, but I think there is a spelling mistake in the command for antsRegistrationSyNQuick.sh... I think it has to be the capital N for SyN, but in nipype/interfaces/ants/registration.py the _cmd is antsRegistrationSynQuick.sh ### Actual behavior Causes a crash when using a node with antsRegistrationSyNQuick with the following message IOError: No command "antsRegistrationSynQuick.sh" found on host c2. Please check that the corresponding package is installed. ### Platform details: I am using nipype 1.0.2, ants version 2.1.
