Hi all.

 

I&#8217;m simulating some different types of membranes using ffgmx for
lipids from gromacs site.

  I plan to use some of the  lipid structure and topology files from
http://moose.bio.ucalgary.ca/Downloads/

When I was doing EM and MD of membrane made of POPE lipids I noticed
something strange: distance between atoms H1 and O7 was about 1.3 A for
every lipid.

  I&#8217;m not sure if this is correct.  Did someone use this pope.pdb and
pope.itp file? 

 Please give me some comment.
