I am currently working on a project that uses 1o15.pdb
It is a structure where RNA and theophylline molecules are bound. I want to mutate the bases of different sites of RNA at the same time.
For example, ACGUACGUACGU mutates positions 2-6 and mutates more than one base to ANNNNNGUACGU, and creates a new PDB file with 45 sequences. Can mutate_bases in X3DNA achieve this function?or it can use in dssr-basic. Thank you for your reply!

Hello! I would like to share with you some recent issues regarding the use of DSSR. First of all, thank you for your great contributions to DSSR and X3DNA, which have helped many scholars and are free for academic institutions to use. My question is as follows:
1. After I got the academic license through Columbia University, I downloaded two versions of dssr-basic for linux and windows. But the windows version of the exe installation package can't open all the time. I have tried it on several computers with win7 and win10, but it doesn't work, so I would like to ask Dr. Lu why.
2. The files in the linux installation package are not in tar.gz format. I don't know how to install it. Could you please tell me. Or is there an installation method I haven't found? I did find it for a long time. So please let me know, thank you very much.  :D

Best wishes
