[gmx-users] Normal mode analysis

[Smith, Micholas D.]

Is your build of GROMACS using double precision? NMA typically is performed with double precision, which is not the default gromacs build.

Subject: [EXTERNAL] [gmx-users] Normal mode analysis

?Hello,


Currently I am trying to perform a normal mode analysis on my pdb file using Gromacs 2019.3.

But during energy minimalisation I can't seem te get my energy low enough. it remains around 10^01-10^00.

I used the attached mdp-files.


Am I doing something wrong? If so, what am I doing wrong and how can I fix it?



Kind regards,


Katrien
