Initially, I would like to apologize in advance in case that my question is naive. Here is the thing. I would like to apply a meta-analysis on different gene expression studies based on ranks. I have found the RankProd library that I would like to use, but the problem is that I want to use only the rank indexing part, avoiding the calculation of the FC.
The reason for this is that I already have the FC for the genes from different studies.
So, I was thinking if there is a way to generate a matrix of ranks based on the FC for each study and after that based on these matrices to do the meta-analysis.
Is it possible?
Thank you very much in advance, Vasilis.
