I made a psf file by using only Chain A, 1 NAD and 1 FMT from my pdb that originally contains 4 chains, 4NAD and 8 FMT.
1) NAD is getting split up when making psf file.
2) FMT originally was inside chain and now its in the corner.
I even tried by using all 4 chains but it still gives me same error. Can anyone suggest how to solve it please.
