[gmx-users] 2 chain protein and VMD

[Acoot Brett]

  Dear All,
 
After the production MD for a 2-chain protein complex (chain A and chain B) was done, I used VMD to observe the trajectory. I want to color the 2 chains in different color. 
 
However it seems during the observation of the trajectory by VMD, VMD treated both of the 2 chains as chain X, and thus the 2 chains cannot be colored differently.
 
Do you have any method or suggestion to color the 2 chains in different color by VMD in the trajectory observation process?
 
Cheers,
 
Acoot
