You loose detail, like the distinction between decane and dodecane. Although, there are two bonds and an angle to make a difference. > Additionally, can i change of the mass of each bead the mass of Decane/3 in > the itp file instead of the default mass for C1 (72 AMU) ? You can do anything you like in modeling. It may make sense :) But different masses on the beads won't give you differences other than kinetic. Cheers, Tsjerk -- Tsjerk A.
