Hi Tony,

You need to open the PAE associated to your best model.
Go to Tools/Structure Prediction/Alphafold Error Plot and select the folder containing your PAE 🙂

Hello

 

I have a commercial license of ChimeraX, I have a question you may be able to help with

 

I have used Structure prediction > Alphafold to predict structures and interactions between 2 proteins and this returned the best_model.pdb

 

But I would like to identify contacts within 8 angstroms, as shown in the Youtube video:

 

https://www.youtube.com/watch?v=TMcjEecFHaI&list=WL&index=26

 

I’m typing the command: alphafold contacts /A to /B distance 8

 

But receive the error:

 

‘Structure best_model.pdb #1 does not have PAE data opened’

 

Do I need to open something? If you can help that would be much appreciated

 

Many thanks

Tony
