Hello,
In combination with the 'DCD file doubles a monomer' I have to add that
when I run this simulation on 6 monomers or less this does not happen. I
need to run this larger scale simulation so that I can monitor interactions
between hexamers and pentamers (this is a part of a capsid). Thank you.
