If you are a new cellfinder user, it is unlikely you want to use these options. They are intended for those migrating from earlier versions of the software
If you have channel numbers that you'd like to carry over into cellfinder
--signal-channel-ids. Channel ID numbers, in the same order as 'signal-planes-paths. Will default to '0, 1, 2' etc, but maybe useful to specify.
--background-channel-id Channel ID number, corresponding to 'background-planes-path'
