[modeller_usage] Nucleic Acids and modeller

Hi!

I need to model a protein complexed to a nucleic acid... I know my alignment should look like: PROTEIN/NUCLEIC-ACID But I was wondering if I should define new libraries in my top file and how do you tell modeller: "Hey, this is a nucleic acid, A stands for adenine!!" (I will be working with poly Uracil...)

Thank you in advance for your help.

Best regards,

Luis Rosales
