Task 2: score based on molecular data

Is there any simple guide or resource (other than the paper mentioned) which can give a basic idea of how to extract the mean RNA expression of 11 proliferation-associated genes? I have not worked with the RNA expressions but just wondered if we can also use that along with mitosis score. Do we have any separate dataset for the Task 2?

It is not possible to use the expressions along with mitosis score. If we already have the expressions, we have the ground truth. The goal of this task is to try and predict this from the image data.
