Hi Alex, I believe that the command and menu selection methods automatically omit the rotamers, so you if your waters are named HOH you could just use command sel #0 & ~:hoh I tested that by using the command before and after showing rotamers for some residue, and both gave the same number of atoms and bonds selected.

Hi Elaine
That perfectly answers my question. Is there also a way to do selection such as select 0 AND not all waters AND not rotamers.
Thank you for reply! Alex

You could make a selection with commands, for example select O ...would select all oxygens select protein ...would select all protein select :trp ... would select all tryptophan residues
or with the menu, for example Select... Chemistry... element... O Select... Structure... protein Select... Residue... TRP
Then after something is selected, you could see contents of the selection (how many atoms and residues) by clicking the green magnifying glass near the bottom right corner of the Chimera window, or write a list of the selected atoms or residues to a file or to the Reply Log (Actions... Write List). The status line also reports the number of selected atoms, temporarily.
