Hi Martini World,
I am trying to reproduce a result related to Bi-lamellar DOPE system. The example application section here, provides a gro, mdp and top file. However, I noticed an inconsistency in the number of lipid beads that are used in the *top and the *gro file. It looks like the *gro file was build for a very early version of martini (not exactly sure which one). The reason I say that is because, DOPE has 14 beads instead of 12. Could anyone point me towards a DOPE topology with 14 beads? Or even better, provide me with an updated gro file that is in bilamellar phase?
Here is the link to the Bi-lamellar DOPE system, www.cgmartini.nl/index.php/example-appli...ons2/lipid-membranes .
Thanks!

If you want to move on to a working system, I would follow the lipid bilayer tutorial on our webpage. It makes use of insane and allows you to generate most bilayers within a second. I'll take a look at the outdated example you are talking about, but for now the above suggested should get you where you want the quickest.

Not sure about the inconsistency but you can find the latest lipid parameters for a lot of lipids in the lipidome. Here's the page for DOPE:

seems that the 'current' version is the one with 12.

Thanks Riccardo. With the old DOPE, which has 14 beads, I can run the example simulation.
