This may be a really simple question, I know, but still... How can I set up a fixed connection between two atoms of a molecule? When I choose the 5th bondtype in my topology-file I get the following output from grompp (though it's processing, so I CAN start mdrun afterwards):
WARNING 1 [file "ethane.itp", line 12]: No default Connect Bonds types, using zeroes Either way I'm not sure how the distance of these two atoms is processed, so there is NO parameter that is specifying this bond-type (and a constraint would be processed by gromacs, wouldn't it? And I don't want it to, cause I want the simulation to be as simple as possible) By the way, I wanna simulate a huge system of ethane and take a look at the processing time per simulated step, is there an output-file thats reading this? Thanks in advance to everyone who is replying, it's so hard when you're stuck. -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS.
