Situs is
an award-winning
program package for the modeling of atomic resolution structures into
low-resolution
density maps e.g. from electron
microscopy, tomography, or small angle
X-ray
scattering. The software supports both rigid-body and flexible
docking
using a variety of fitting strategies. Situs
is developed by Willy Wriggers and collaborators: biomachina.org.
This software is distributed free of charge
under the GNU GPL
license and includes the C/C++ source code, an implementation of
the FFTW library, online tutorials,
and
documentation. The
development is supported by NIH.
The name of the package was derived
from the botanical term for the arrangement of the parts of a plant:
| Situs, n. [L., situation.] (Bot.)
The method in which
the parts of a plant are arranged; also, the position of the parts.
--Henslow. |
We provide a number of advanced
docking tools for a variety of fitting scenarios, including rigid-body
fitting and flexible fitting (see Methodology).
The software consists of individual,
stand-alone programs for format conversion, analysis, visualization,
manipulation,
vector quantization, and docking of 3D data sets. Each program is
self-explanatory
as the user is asked to enter all relevant information in a terminal
window in a UNIX, MacOS X, or Windows workstation. The modular design
of the
package allows the user to maintain flexibility in its application. The
documented source code written in C and C++ can be ported to a variety
of
architectures. File names are passed as arguments to the programs of
the
distribution:
