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 [image: image.png] 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
