my pdb file for dna and protein contains 640 and 1130 atoms respectively. if I want creat a new pdb file for studying pr-dna interaction, should be numbering and order of numbers changed? how?


Numbering is the least of your worries, generating a reasonable starting structure is much more difficult, if the protein and DNA molecules are in separate structure files. Once the system is assembled, it can be renumbered (genconf -renumber); the order is dependent only upon the order specified in the [molecules] directive of the topology.
