Hi Laurene, Like Dave, I am somewhat curious why you need you would need Amber types for an entire protein. Nonetheless, you can write such a file by adding “gaffType true” to the command you are using to save the Mol2 file (after running addcharge on the structure, which adds the GAFF types).

I am a master student currently working on a project where I need to generate a mol2 file with amber atom types for a protein.
I don't have a ChimeraX answer here, but rather a question: why do you need a protein mol2 file with Amber atom types? Amber workflows would not create a mol2 file for an entire protein; but of course, you may need such a file for some other purpose. If so, we may be able to find some Amber tools that does this (or avoids needing it), if the ChimeraX folks themselves don't have a solution.
