[Chimera-users] measure surface area

Hi! i want measure several selected residues surface area and volume, but in the reply log, it always give the total surface area and volume of the protein, how can i get only the selected residues surface area? because this residues make a cavity , which may binding substrate. in addition, the castP server can't give me the pocket i wanted, because it give a bigger pocket than i wanted. thanks in advance！ liuqing chen -- Liuqing Chen School of Life Science & Biotechnology Minhang Campus Shanghai Jiao Tong University No. 800 Dongchuan Road Shanghai 200240 P.R.
