Dear Mark,

Thank you for your quick reply. I mean if there is any way we can control the frequency for coupling the temperature if we still use GROMACS V4.0.7 on LINUX?

Many thanks,

But we always received a warning said it was a unknown parameter during "grompp" in GROMACS V4.0.7 on LINUX. I also tried it by GROMACS V4.5.4 on my MAC OS, it was done successfully. Unfortunately, our HPC uses GROMACS V4.0.7, so it is a problem for us.
