Hello Nilesh, it sounds like you have a similar problem to mine, except my original run has large energy fluctuations and the rerun does not. By chance is your gromacs version installed with mpi on? i think i have narrowed my problem to a bug in the installation with mpi. If you search for my "i

Re: [gmx-users] Distance restraints exploding system

2013-09-05 Thread Trayder Thomas
To wrap this up for anyone who stumbles across this in the future: The 'solution' I ended up going with was to avoid using hydrogen atoms in the restraints, instead restraining to the e.g. methyl carbon and adding a fudge factor to the restraint length to account for the C-H distance. This results

Hi all, Need your help to explain more about this multiple chain.I would like to do a simulation with a multiple type identical protein. By using the instruction that gromacs wrote in 'http://www.gromacs.org/Documentation/How-tos/Multiple_Chains', seem that i'm a bit lost when it tells us to us th

Thanks Justin for the quick reply. by the way after i solvated the protein with water and i change the amount of the protein that i want for example 8 and the amount of water that already in is 20453.But after i proceed with grompp the result shows that my .top file have different number of config

Hi guys do you have an idea what is causing the segmentation fault with g_cluster? I do the following 1 . I combine trr files from different simulations using trjcat and select backbone atoms only trjcat -f ../../*C/runs/*/*trr -cat -n index.ndx -o trajout_combined.xtc 2. I make a new .tp
