To use Pscan you will need a C++ compiler like gcc (http://gcc.gnu.org/) and the
Gnu Scientific Library (http://www.gnu.org/software/gsl/) both installed in your system.
To compile the binary from the source file simply type:
g++ pscan.cpp -o pscan -O3 -lgsl -lgslcblas
If all is ok than you will find a binary file called "pscan" in the same folder.
To allow the use of Pscan from every folder without having to type the whole path to the binary file every time you use it,
it could be useful to have a symbolic link to it in your "bin" folder.
(For help on symbolic links type: man ln )
Please note that this archive does not include matrices and other related stuff that may be useful to run Pscan. You can download them for your organism(s) of interest at: http://220.127.116.11/pscan/source.html .
