About ParaSurf™

ParaSurf™ is the basis module that uses output from a semi-empirical molecular orbital program like VAMP or EMPIRE™ to construct molecular surfaces and calculate local properties and descriptors. Surfaces may be generated by shrink-wrap or marching-cube algorithms and the former may be fit to a spherical harmonic series. ParaSurf™ was originally introduced in 2005.

ParaSurf™ can also generate local enthalpies and free energies of solvation and integrate them over the entire molecular surface. The application has the ability to read Surface-Integral Model (SIM) files that allow it to calculate properties such as the enthalpy and free energy of hydration plus the free energies of solvation in n-octanol and chloroform.

Program versions of Parasurf™

ParaSurf™ 20

ParaSurf20™ has now been released. In addition to algorithm and performance enhancements, it can now use EMPIRE™ -e.h5 HDF5 output files as input in addition to VWF and SDF files. ParaSurf20™ can now also process heterogeneous lists of input files.
The ParaSurf20™ manual is available online.

ParaSurf™ 19_A2

Revision A2 now uses the EMPIRE <Hamiltonian>.par file, rather than the Vhamil.par file, with SDF inputs.

ParaSurf™ 19

ParaSurf™ includes parallel performance enhancements, in particular for defauilt surfaces and for autocorrelations.

ParaSurf™ 12 (free academic version)

ParaSurf™ was released on September 1st 2012. This version is freely available for bona fide academic users. The program can be used with the free academic version of EMPIRE™, or with the freely available Cepos Mopac6.To register and download the program, please click here.
