[gmx-users] POPC Bilayer box

[Simon Wang]

Hello, David:

I used either
'genconf -f popc.gro -o popc4n.gro -nbox 2 2 1'
or 'genconf -f popc.gro -o popc4n.gro -trj popc200ps.trr -nbox 2 2 1'

The version I used is GMX3.2.1. Please let me know if I missed anything or 
there is better way to scale the box size. Thanks a lot.

Simon
