Hii everyone!!
I am using RNA with ions for MD simulation, but I encounter an error in pdb2gmx command Processing chain 3 ‘A’ (1 atoms, 1 residues)
ERROR:
Problem with chain definition, or missing terminal residues. This chain does not appear to contain a recognized chain molecule. If this is incorrect, you can edit residuetypes.dat to modify the behavior.
8 out of 8 lines of specbond.dat converted successfully
I am using Amber FF… please help me out… Thankyou in advance!!
