[chimerax-users] Enquires about predicting protein interaction with chimeraX/AlphaFold

[Yiling Lan]

Dear Elaine,

Thank you so much for your fast response.
I just checked the documentation and I'm a little uncertain if I was understanding it correctly.
May I ask if I want to predict a protein complex, all I need to do is to put a comma between the 2 sequence and if there is an interaction, the complex will be automatically predicted and there is nothing more I need to select?
Again, thank you so much for your help.
Best Wishes
Yiling Lan

Dear Yiling Lan,
The video is older.  In the newer versions of ChimeraX, the AlphaFold tool does not have this option (it was removed), so you don't have to worry about it.  I would recommend using the newer versions of ChimeraX because there is a continuous improvement process.  Also, the older versions may not work any more because AlphaFold or ColabFold itself has also changed during this time.

The current (new) documentation for the AlphaFold tool is here:

I hope this helps,
Elaine
