[gmx-users] residue IDs are not ordered in gro file.

Hi, there:

I found that in gromacs version 4.5.1, the residue ids are not ordered  
consecutively as before in the .gro file. For example, if I have two  
chains in the protein, then the residue ids will be ordered with  
respect to each individual chain, rather than reordered to be a  
complete system. I also attached one segment in the gro file for  
illustration.

Is this supposed to be a new feature? It's actually quite inconvenient  
when trying to make selection in VMD.

Thanks,
Bin
