Techniques for Expedited Sampling
TUTORIAL A7: Replica Exchange
tutorial covers how to setup, run and postprocess replica exchange
simulations using multisander and Amber 10 or later.
TUTORIAL A22: Using Accelerated
Molecular Dynamics (aMD) to enhance sampling
In this tutorial,
we will learn how to use AMBER's implementation of aMD to enhance sampling.
In this tutorial we focus on the steps necesary to prepare and run an aMD
simulation. We use the work we published on the discovery of long lived
conformational transformations in the Bovine Pancreatic Trypsin Inhibitor
(BPTI) protein. We follow the preparation of the files and give sme
information about aMD reweighting.
TUTORIAL A26: Adaptive Steered
This tutorial provides
detailed instructions on how to perform Adaptive Steered Molecular Dynamics
(ASMD) simulations. Compared to Steered Molecular Dynamics, ASMD has been
shown to converge much faster while reducing the computational cost. The
tutorial calculates the Potential Mean Force of unfolding a small
alpha-helical peptide using two different velocities.
TUTORIAL A5: Nudged
Elastic Band (NEB) simulations
This tutorial uses a feature that is only
available with Amber v11. As such you need to have Amber 11 installed to run
the calculations in this tutorial, if you are using Amber 9 or 10 then you
should use the older NEB
tutorial. In the nudged elastic band method, the path for a
conformational change is approximated with a series of images of the molecule
describing the path. Minimisation of the entire system, but with the end
point structures fixed, provides a minimum energy path. In this tutorial we
will use the NEB method to predict a pathway for a conformational change in
