Thanks to all for the useful replies. BTW, which force field will be good option for simulating united-atom (acyl chain) POPC membranes? Many thanks Anu On Fri, Jun 19, 2015 at 5:15 PM, Thomas Piggot wrote: > Good to see the membrane structures have been changed/fixed. I think it > was December

Good to see the membrane structures have been changed/fixed. I think it was December 2010 when I last downloaded the POPC one! I did port over the lipid parameters for C27-UA a good while ago but haven't got around to the C36-UA parameters yet. On 19/06/15 16:55, Justin Lemkul wrote: On 6/

Well, the CHARMM ff is not entirely all-atom: http://pubs.acs.org/doi/abs/10.1021/jp410344g As for downloading the structure, I would be slightly careful with the link that Justin provided for POPC as (well, based upon the last time I used it anyway) there were a different number of lipids in

Dear Justin, Thanks for the inputs. May I know which force field can be a good option for united atom (acyl chain) POPC?. A recent article ( http://pubs.acs.org/doi/abs/10.1021/jp401403b) says CHARMM27 united atom model is adopted for POPC. Unfortunately the web-link you mentioned here have only t
