hi dr.xiangjun
im a new user of 3dna software
Sorry to take your time
I'm going to design a single-stranded DNA structure for designing the switches that work with the pH.
Do you have a file for full software training? Especially for the design of clamp switches.
I want to fully understand rebuild and mutate analysis of this software.
Does this software give us the possibility of protonizing the structure?
thanks for your help

General discussions (Q&As) / design triple helix

« on: May 21, 2019, 02:59:19 am »

Hello . I am a new user
I reviewed the questions of others. Unfortunately, I did not understand how to design triple helix. Using fiber -pauling , I succeeded in making triple helix . But When I use find_pair command, the software shows the following text:
C:\Users\Sima>find_pair triplex-C10C10C10.pdb

handling file <triplex-C10C10C10.pdb>
no base-pairs found for this structure
triplex-C10C10C10.pdb
triplex-C10C10C10.out
    2         # duplex
    0         # number of base-pairs
