'mris_calc' accepts as inputs volumes or "curvature" files. Calculations on labels don't make sense in the context for which "mris_calc" was written -- what would an operation like "label1 multiply-by label2" even mean?
Having said that, 'mris_calc' does support labels in as much as using a label as a filter or ROI on which to do some calculation.
What you're looking to do, i.e. process labels and filter out non-overlapping from overlapping, isn't supported by 'mris_calc'.

As far as I can tell - and I may very well be using incorrect syntax - mris_calc needs volumes as inputs and does not accept labels. Does mris_calc accept label files as inputs, for instance in a command like: "mris_calc roi2.label and roi3.label"? If so, could someone point me at the correct syntax to use?
Thanks,
