having multiple files as optional input like this doesn't seem to work for me : http://nextflow-io.github.io/patterns/index.html#_optional_input
e.g. how do I do this if I have set sample_id, file(bla) from blablabla_ch ?
Otherwise I have to duplicate the channels and have multiple processes etc pp which is kind of nasty :-D

the trick it's the same you should use a special file name to mean no file
