Hi, Nicolas. Yes, one image is stored as three files, but not really RGB. These are images from a special instrument (imaging flow cytometer). Two images are Red and Green, and the third is the so-called brightfield image. As I understand it, an additional complication is that in all channels the images are grayscale. Let me explain. We tint the cage with special dyes and illuminate them with a laser. The device fixes the intensity of a particular color in different channels and the usual image in the optical range, but the pictures themselves remain gray. I will attach an example of how the image of one cell looks like this. Answering the second question - I would like to first use some modification of the standard architecture.
