Combining segmented ROIs into single ROI

[bkinnersley]

Hello,

Thank you for a very helpful package!

I would like to combine multiple segmented ROIs (e.g. CD45, Pan-CK, Rest) into a single "Full" ROI, and wanted to check if there was any pre-existing function available/recommendations on how to go about this? For example is it reasonable to sum raw counts or combine post-normalisation?

Thanks very much

Best wishes

Ben
