I have maize genes and their rice orthologs identified through synteny analysis on gramene, and I want to make a circular representation of these with information on their genomic positions on the respective species including rice and maize QTL physical positions they fall within. I have spent much time trying to figure out how to do it with Circos, SOFIA, or other related software but I think I just lack the basics. Therefore, even a detailed tutorial (for real beginners) would be so helpful. Thank you.
