Hello,

I am doing LIVE/DEAD staining of biofilms on different surfaces and taking z stack images by CSLM ( Olympus Fluoview FV1000).

Then I am using COMSTAT to estimate biomass thickness roughness coefficient etc.

I am following the procedure detailed on COMSTAT 2.1 manual for making the stacks and image conversion and so, but I am getting different values for these parameters depending on the channel (red of green), and the two value are sometimes very different.

Is this usual or I am doing something wrong?

Many thanks
