Dear Tom Goddard

I would just like to know if there is any command in Chimera, which allows me to identify the atoms that are part of the total solvent accessible surface area (SAS).

I will try to explain my question with an example.

First,

Commands:

open 121p

select :62

show sel

Select>residue>all nonstandard

Actions>Atoms/Bonds>delete

select :62@OE1

surface sel

As shown in the image, I have identified an atom that forms the surface accessible to the solvent. However, to identify the total atoms of that protein I have to select atom by atom, which implies a lot of time and more if I have several proteins.

So, I would like to know, if it´s possible to obtain a command that allows me to select all the atoms at the same time, specifying the atoms that are part of the total solvent accessible surface area(SAS).

Thank you (:

kind regards,

Susanna
