I am trying to use the "bond" command in xleap to create disulfide bonds in a protein. I use the following syntax on the example below:
bond cyx.117.SG cyx.129.SG
The bonding fails, and xleap gives me the following error message:
bond: Argument #1 is type String must be of type: [atom]
usage: bond <atom 1> <atom 2> [order]
Other information: the protein possesses two chains, A and B, and a few of the disulfide designations are the same in both chains.
Do I need to specify the chain designation with the "bond" command? If so, how do I do this?
I have followed this procedure successfully many times before. I can't figure out what I am doing wrong.
Thanks!
