Is there any way to provide MSA of receptor for af2_metrics.py ? #12

Hi,

After design protein binder using hallucination.py, I tried to validate results.

According to the tutorials, first I run the trfold_relax.sh,

and then run the af2_metrics.py .

However, the modeling result was implausible especially in the receptor region.

In the case of my receptor, the modeling result was plausible only if the MSA is provided.

I thought that the implausible result of af2_metrics.py might be originated from the modeling without MSA.

So, is there any protocol or alternative way to validate my result ?

Sincerely, jongseo

for binder-receptor complexes, you want to use af2_interface_metrics.py rather than af2_metrics.py. however, in order to use this script you will need to combine your pdbs into a silent file using silent_tools https://github.com/bcov77/silent_tools (which requires an installation of pyrosetta).

this script inputs a template for the receptor and puts an initial guess for the binder, as described in this preprint https://www.biorxiv.org/content/10.1101/2022.06.15.495993v1
