[gmx-users] anisotropic B

[rams at poori.biochem.uiowa.edu]

hi!

i am trying to generate anisotropic B-factors from a 1ns run using g_rmsf.

 g_rmsf -aniso -f 1ns_nr.trr -s 1ns_nr.tpr -oq aniso.pdb 

I get isotropic B's - no ANISOU card in the output pdb file.
More surprisingly the iso-B's are different than when I dont use the aniso 
card.

I am using gromacs 3.1.3...

what am i doing wrong?

Thanks.

Rams.
