Hi Dave,
I've tweaked the RGB grey merge from the imagej website:
http://rsb.info.nih.gov/ij/plugins/rgb-gray-merge.htmlto allow the subtract a user defined percentage of the fluorescent channels from the grey prior to merging.
You can get it with the MacBiophotonics ImageJ bundle or I can email it to you directly off list.
Any feedback much appreciated.
Tony
