Hi Gary,

  The swapna command lets you change a nucleic acid base, for example, to change residue 18 in chain C from a T to a G use

open 1rsb
swapna G :18.C

Dear Tom
Thanks for many answers to our previous questions.
 
I have one more  question to our loved Chimera program.
 
I have a NDA model (PDB), but the sequence is not right. Is there any way to use this DNA model to generate a new model with a right order of sequence? In other word, if is there an automatic/ simple method (by comment lines) to replace the sequence by the correct one in Chimera?
 
Thanks a lot!!
Gary
