[gmx-users] L-BFGS energy minimization not leading to wrapping of dna around cnt

Okay, thanks. But then does it make any big difference on mdrun if we don't
minimize energy first?
And one more thing, any idea how long it may take to run md for 367 atoms on a
laptop with 2GB ram, and dual core 1.4GHz processor. I am just wondering if it
is possible to get any results from mdrun on laptop?

Energy minimization and dynamics are independent processes. You should not
expect large structural changes during EM with any of the methods.

Always start with the primary literature:
