I had a pdb file containing co-ordinates for a number of individual lipid monomers that i performed the g_order command on to obtain a .ndx file. At this point i have a .ndx file that i am not quite sure what to do with in order to have meaningful insights. I will appreciate any help with this issue. Thanks!
