Search Results for "coordinates"

...The exemplary results were obtained by application of the adaptive Gauss quadrature. The implemented algorithm is described in my paper: "Numerical calculation of overlap and kinetic integrals in prolate spheroidal coordinates", International Journal of Quantum Chemistry, Volume 108, Issue 2, Year 2008, Pages 249–256 http://onlinelibrary.wiley.com/doi/10.1002/qua.21485/full

A Windows software for generating structures of nanotubes and some fullerenes. You can generate any kind of nanotubes (n,m) with chirality indices n and m ranging from 0 to 60, and the number of repetitive unit cells up to 50. You can also generate some typical fullerene cages from C20 up to C320.

PDBManip is a free program for editing and manipulating PDB (Protein Data Bank) files. It has a graphical user interface and it is provided as an executable file for running on Windows® operating systems. There is a bunch of free programs on the internet for the same purpose. What discriminate between PDBManip and those programs is that PDBManip uses AngelScript language which is very similar to C/C++ language, to write scripts to do our editing tasks. I know that the text-manipulation...

...The Visualization of Protein-Ligand Graphs (VPLG) software package computes and visualizes protein graphs. It works on the super-secondary structure level and uses the atom coordinates from PDB files and the SSE assignments of the DSSP algorithm. VPLG is command line software. If you do not like typing commands, try our PTGL web server: http://ptgl.uni-frankfurt.de/

...The particle fitting routine is provided by an external library written in C. The results can be exported into the Matlab Workspace or the trackID, frameID and xyz coordinates are saved into files.

Develop a basic understanding of the behavior of polar spherical coordinates through selected examples. Provide sample files for diverse mathematics engines

md-utils is a set of command line tools written in C designed to perform certain operations and analysis on the molecular dynamics data. The supported operations involve trajectory coordinate transformation to the COM system, Cartesian coordinate transformation to selected internal coordinates and to projected normal mode coordinates, trajectory merging, selecting subsets of trajectory frames, selecting subsets of atoms, permuting atoms, etc. Analysis tools involve 1D, 2D and 3D data binning (histograms), volumetric data handling, etc. A small library, libmd, is an abstraction layer that serves data exchange among different tools.
