You can just use the "select" command with these amino acid categories, for example:<br class="">
<br class="">
select polar<br class="">
select nonpolar<br class="">
select hydrophobic<br class="">
<br class="">
See:<br class="">
<<a href="https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/select.html" rel="noreferrer" target="_blank" class="">https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/select.html</a>><br class="">
<<a href="https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/atom_spec.html#builtin" rel="noreferrer" target="_blank" class="">https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/atom_spec.html#builtin</a>><br class="">
<<a href="https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/selection.html" rel="noreferrer" target="_blank" class="">https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/selection.html</a>><br class="">
<br class="">
.... and then the Selection Inspector says how many residues are selected. You can open this tool from the menu (Actions... Inspect) or by clicking the magnifying-glass icon near the bottom right corner of the Chimera window, <br class="">
<<a href="https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/inspection.html" rel="noreferrer" target="_blank" class="">https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/inspection.html</a>><br class="">
<br class="">
and just keep that tool open the whole time. Then when you use the different select commands, it will say near the top of that dialog how many residues and atoms are selected.<br class="">
<br class="">
There are beginner tutorials for starting to use commands, for example <br class="">
<<a href="https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/getting_started.html" rel="noreferrer" target="_blank" class="">https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/getting_started.html</a>><br class="">
<br class="">
...and the "working with commands" section in:<br class="">
<<a href="https://www.rbvi.ucsf.edu/Outreach/Tutorials/GettingStarted.html" rel="noreferrer" target="_blank" class="">https://www.rbvi.ucsf.edu/Outreach/Tutorials/GettingStarted.html</a>> <br class="">
<br class="">
I hope this helps,<br class="">
