Rosetta Double changing mmCIF chain ID

[Anonymous]

Hi everyone!

Perhaps a beginner question. I am having problems with Rosetta changing the default chain ID (double letter) when reading and writing as mmcif. Specifically I am relaxing a long list of proteins into cryo-em density using rosetta scripts and and the resulting mmcif files written by rosetta have the “auth_asym_id” truncated from ex. “Ac” -> “c” or “Xm” to “m”. Does Rosetta not support double letter chain IDs internally? Is there any solution to this problem?

Best and thank for any help,

Victor

Hello,

Unfortunately rosetta does not support multi-letter chainIDs.  It is something that I have worked on fixing, but haven’t had the time to complete. I hope to finish it in the future, but I do not know when that will be.

Hello,

Thanks for the rapid answer, I will have to do some scripting then!

Best,
