Dear NAMD users
I carried out TMD simulations of a polypeptide of hemaglutinin. I was analysing log file but I do not know what the third and fourth columns means. I think the last one has information about rmsd respect target structure, but i am not sure. I wait somebody can help me with it. Thanks
Andres

I used the following script to run the simulation:
