Hi André, I added two options "replace" (default true) and "name" (default "PAE Contacts") to the alphafold contacts command. The replace option determines if existing contact pseudobonds (in the group with the specified or default name) are deleted. If replace is false the new contacts are just added to any existing ones. The name option gives the pseudobond model the specified name. So you could use alphafold contacts /A to /B alphafold contacts /B to /C replace false alphafold contacts /A to /C replace false to put all the contacts in one pseudobond submodel. If instead you wanted them in 3 different models you could use alphafold contacts /A to /B name "AB contacts" alphafold contacts /B to /C name "BC contacts" alphafold contacts /A to /C name "AC contacts" This will be in tomorrow's (Oct 11) ChimeraX daily builds.

 Hi André,

The "alphafold contacts" command creates a submodel of the atomic structure containing pseudobonds with the submodel named "PAE Contacts". If you rename that submodel then it won't replace it when you do the second alphafold contacts command on the same structure. For instance, if the structure is model #1.

alphafold contacts /A to /B rename #1.1 "AB contacts" alphafold contacts /B to /C rename #1.2 "BC contacts" alphafold contacts /A to /C

This should be easier to do. I should add an option to the alphafold contacts command "replace false" that automatically uses new names for each group of pseudobonds. I've made a request for this.

Hi,

Is it possible to draw contacts (PAE, alphafold) between more than just 2 subunits? e.g.: alphafold contacts /A to /B AND alphafold contacts /B to /C AND alphafold contacts /A to /C

Righ now, a new command deletes the old contacts. Not sure about a syntax that would combine/add those

Thank you very much!

Best André
