[Chimera-users] select a specified residue

Dear Sir, It is nice to use the amaizing software of UCSF Chimera. I can select a kind of residue such as all 'SER's and label them, while I am able to select a specified number of residue, such as the 200th residue 'Ser'. Could you please show me how to do with this? Thanks a lot. Best, zhengfeng ------------------ Zhengfeng Zhang School of Life Science Central China Normal University.
