Re: [gmx-users] Urey bradley term in the sum of energies
Nicolas SAPAY wrote: Hello everybody, I've got an awful doubt on how the Urey-Bradley (UB) term is taken into account in the potential energy. When an angle has got regular and UB parameters, how this will appear in the .edr file? If you have a force field with both angle function 1 and angle function 5 (IIRC, for U-B) defined for the same set of 3 atoms, then to the best of my knowledge, GROMACS will do both blithely and the output will go into "Angles" and "U-B" in the expected fashion. Certainly this happens when such functions are defined for different sets of 3 atoms. Note that from GROMACS point of view, the U-B term includes both the angle stretch and the harmonic position stretch. CHARMM the program lists only the latter as U-B. The angle energy will only appear in the UB term only or it will be splitted between Angle and UB terms? I guess that both parameters are used in the computation but I'm not sure whether they are added before be printed in the .edr file or not. I'm not quite sure what you're asking, but the structure of the bonded interaction code is such that all of the angle functions of type 1 will contribute only to "Angles" and all of the angle functions of type 5 will contribute only to "U-B".

Hi Sangeeta, Let me ask you few questions in order to solve the problem. Are you sure your do_dssp prog were running or it was hanged? To make sure please try using verbose output using -v option. Is your computer shared among too many people? What is the file permission status of dssp? To find out use: ls -l /directory/where/you/put/dssp If you see any restricton to file permission change it to chmod a+rx dssp Hope this will help.

[gmx-users] membrane set up!!!
The below-mentioned lines (from forum) do not work for me!! I am dealing with DMPC instead of POPC and I hope that is not making any difference!! kindly help, Priyanka S. ""Hu Ugur, actually you don't have to care to run the lipid pdb by Tieleman through pdb2gmx at all - just copy the respective lines out of lipid.itp into ffG43a1bon.itp and ffG43a1nb.itp (or the force field you want to use) and put "#include pope.itp" into your *.top file - et voila, you're done. Attention: the lipid parameters are optimized to be used with SPC water! So pay attention when using TIP3... Greetings Steffen"" Need Mail bonding? Go to the Yahoo!

[gmx-users] itp files in membrane simulation
Dear all, I want to use lipid.itp & dmpc.itp for a bilayer simulation, and I have gathered this information so far that one has to manually modify these itp files in order to use the latest force fields, ie, G43a2 etc. Does this include lipid.itp file too which involves various lipid-GROMOS interactions? Also, is there any command or program which when applied carries out the required combination rules for evaluating lipid-GROMOS interactions or that also has to be done manually!! I shall be highly thankful to you all, regards, Priyanka S. Do you Yahoo!? Everyone is raving about the all-new Yahoo!
