The program NSC is a piece of surface code written in C with an easy interface to any user program which requires as one of the tasks the calculation of surface, volume or surface dots. The user program simply includes "nsc.h" as header file and invokes the subroutine NSC.
Subsequently, "nsc.c" is compiled and linked with together with the user code.
In many molecular biological tasks, it is not the surface of a molecular ensemble per se which is necessary. In most cases, surface and volume data has to be calculated in a special user context. This is just the motivation for NSC.
NSC is included directly or in a modified form in
There is a page describing the methodology, the syntax and the usage of NSC
The file you get is 'tar'ed and compressed using the UNIX 'compress' utility.
The size of the compressed file is about 25 kB.
Uncompressing and unpacking it, a directory 'NSC.2' containing the C-source, a header file and the file readme.nsc with more informations will be created.
