Hello Umanga Jmol will always use the residue numbers that are written in the pdb file (not the order in the chain or in the file). So, your problem seems to be in the exact data you have in your pdb file.
That said, there may be a way for Jmol to find out the length of chain A and add it to the actual residue nr. in B. But I would say that is a non trustable solution for other models (even for this, see below). More things: 1. There is some error in the numbering of your first example: it cannot go from 98 to 97. a look at 1uj3.pdb gives this: chain A goes from residues 1 to 214 chain B goes from residues 301 to 517 So your offset of 215 is not valid either. 2. Your commands are OK, but you can use simpler notation for residue numbers: select :a and (resno > 97 and resno < 106); color red is the same as select :a and 98-105; color red or even select 98-105:a; color red ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
