Hi, Well, I have a much simpler solution - there is no reason whatsoever to use fortran on ia32 or x86-64 since Gromacs will always use the much faster SSE assembly loops. Cheers, Erik On Sep 13, 2007, at 8:44 AM, Diego Enry wrote: This works for me: % vim /etc/ld.conf /opt/intel/mkl

Hi. Yes, but that is the "gcc solution". No prblem with those, except for giving away the "challenge" to make it work with intel compilers. Basically: I couldn't find a way much better. The way I trid in the time I tried, included compilation of the loops and only the loops using gcc to make the

Hi, I am wanting to solvate a protein w/o adding H2O to its interior. Reasons: 1. I am interested to know how the structural H2Os behave initially w/o interference from added H2O. 2. Added H2O also introduce steric constraints that prevent EM from achieving its goal, even w/o constrain

Hello, Thanks for the rapid response, although I am not sure I completely understand what you mean. The accelerate option adds a constant acceleration to whatever atoms I choose with acc_grps. However, if I want a uniform shear, I need to give atoms an acceleration dependent on their positio

Dear GMX users, I uploaded a wrapper to run the Multiprot program using output from Gromacs to the user contributions in the GMX site. Multiprot, http://bioinfo3d.cs.tau.ac.il/MultiProt/ , performs structural alignment based on geometry, not sequence, and thus it allows the alignment of two protei
