Re: [gmx-users] Berger lipid
Dear Peter, Thanks for your link and the article. I'd like to know more about your paper. You've mentioned in it that the temperature of POPC equilibrated, is 310 K. As I saw in Justin's tutorial , 323 K is proper, however it was a different system simulated and also many parameters are not the same as your system . Would you telling me about the reason of 310 K?

Re: [gmx-users] Berger lipid
323 is proper for a higher melting point lipid like DPPC. You can easily simulate POPC at 300, and many other people have done so. In fact I received criticism from a reviewer as to why I picked an elevated temperature of 310, despite the fact that 310 is physiological temperature (to make some experimentalist reviewers happy). Some early rhodopsin runs were done at 310 and I'm pretty sure that was included as a reference in the rationale for the elevated temperature (besides the standard 310 is well above the solid phase transition temperature for POPC line). Neither the g_membed authors nor Klauda run POPC above 310K if I remember correctly. On 2012-06-30 07:33:38AM -0700, Shima Arasteh wrote: Dear Peter, Thanks for your link and the article.

Re: [gmx-users] Berger lipid
Hi Shima, The lipids.rtp file in the charmm36.ff folder has many different entries for lipids. All you need to do is to run pdb2gmx with just one of your lipids of interest. This will produce a .top for this one lipid which is trivial to convert into an .itp (see Chapter 5 of the manual).

( in your tutorial it's written lipid.itp - Berger lipid parameters ) You do not need the so-called lipid.itp as it is for a completely different force field. The Berger lipids are a united-atom parameter set derived in 1997 from a hybrid of OPLS and Gromos parameters. They are typically combined with Gromos force fields. -Justin -- Justin A.

RE: [gmx-users] Berger lipid
Uh didn't we go through all of this like more than a month ago? I published a paper using C36 POPC and even a linked to my popc.itp for it on this list... Of course Shima is welcome to pdb2gmx his own POPC, which I am fairly certain will result in an identical file... Lipidbook seems to only have C36 POPE. I guess maybe I will upload ours.

[gmx-users] Berger lipid
I am sure that a lot of this could be avoided if the gromacs users-list search feature worked. Every search that I do returns ten to one hundred versions of each hit, making it nearly unusable. Google is ok, but it doesn't search the gromacs list nearly as well as the old specific search on the gromacs website did before the website changes. Given the current state of the list search feature, it's not really feasible to ask people to search first, unfortunately.

Re: [gmx-users] Berger lipid
Yes, I remember now...you are right :) But I didn't know the linked you sent me, was your own output! However I wanted to know if it is necessary to produce the .itp file on my own or not. I still have this link, so will cite to you. It would be a good idea to see its package in lipidbook too.
