Is there a way to perform regex in the output parameter processing
I have the following input string parameter
‘/data1/nyue/projects/workflow-languages_git/CWL/vfx/granular_steps/python/output/test.$F4.exr’
which I’d out to do some regex magic to the following
‘/data1/nyue/projects/workflow-languages_git/CWL/vfx/granular_steps/python/output/test.%04d.exr’
Is there a way to call regex ?
