[gmx-users] g_cluster warning

[Preeti Choudhary]

hello everyone

I am trying to cluster my data using g_cluster.I simulated the whole
protein. I did the g_cluster analysis with only certain region of the
protein which I specified using an index file.The program runs fine and
gives 1 cluster.My concern is the warning it gives which states that :-

WARNING: rmsd minimum 0 is below lowest rmsd value 0.0247473


what exactly this warning means ???

-thanks
