Hippo is a software package for simulation and analysis of bio-molecules at an atomic level. It has been specifically developed for very efficient protein folding studies in aqueous and membrane environments. The code is very fast due to optimized and hand-coded assembly routines which make use of fast multi-media instructions on modern x86 cpus. Hippo is (partially) parallelized (using industry-standard openMP).
Download
Binaries will be publicly available from the Biowerkzeg.com download page for Linux, Windows, and Mac OS X (Intel platform only). For immediate access to beta-versions please email martin-AT-ulmschneider.com.
Features
Simulation methods
- Molecular dynamics (MD) in NVT, NPT, NVE ensembles
- Metropolis Monte Carlo (MC) in NVT and NPT ensembles JACS2004,JPhysChemB2006
- Replica exchange with MD and MC
Force fields
- OPLS-AA Jorgensen1996,Kaminski2001
Solvation models
- explicit solvent (water: TIP4P Jorgensen1985, SPC Berendsen1981)
- Generalized Born implicit solvent (GB/SA)
- Generalized Born implicit membrane (GB/IM) Proteins2007,BJ2007,Proteins2005
Enhanced productivity
A number of features make it easy to use Hippo so that one can spend more time on working on problems and less time on setting up structures or dealing with system crashes:
- seamless restarts
- intelligent pdb structure loader: reads most pdbs, can complete missing atoms, and builds the topology
Analysis
A growing number of analysis tools are built into Hippo, for instance
- adiabatic translation+rotation energy scan (to determine the Generalized Born energy of a peptide in a membrane) MMB2008,BJ2006
- RMSD
- helicity
The output format is a standard pdb-movie; thus many other analysis tools can also be used.
