Backward mapping fails with index out of range error was created by khZhang
Dear Martini Users,
I am trying to convert a CG system back to full atom resolution. Upon running ./initram (version downloaded from github.com/tsjerk/backward ), mapping files for Martini 3 obtained from bottom of this tutorial.
The command I used is:
And I see the following error:
I've looked through the forum for similar errors and tried the suggested fixes (checking mapping files and make sure that they list the same atoms as topology file, trying to backmap a single chain first, backmapping a single residue). But regardless of the changes I make to the mapping files (I did edit 3 mapping files, hope I didn't break anything. The mapping files were for ASP, GLU, and HIS), I would still get the same error about index out of range at that same line. And I cannot backmap either a single chain or residue.
Does anyone have any idea what could be happening here? I can provide the input files in a link. Any help is greatly appreciated!
Thank you in advance,
Doris
