LINUS Version 1.0

The LINUS distribution is a suite of programs for exploring conformational 
ensembles of peptides and proteins. The core of LINUS is a torsion angle 
Monte Carlo simulation application that allows a restrained Monte Carlo 
move set with a simple atomic interaction energy acceptance criterion. 

LINUS is written in Python although some routines are also provided as C code.
The C routines will be called if they are compiled but they are not necessary.  
Therefore you should have installed on your system PYTHON and a C compiler. 

If you are running Python on a Intel 386-compatible processor you should also 
obtain PSYCO, a specializing compiler, which will speed up LINUS significantly. 

This distribution should install on most flavors of UNIX including MacOSX.  

The LINUS distribution is a compressed tar archive: 

linus.tar.gz 

which can be unpacked with a command similar to: 

gunzip -c linus.tar.gz | tar xvf - 

When you unpack this distribution you will get two directories below the linus/ directory: 

manual 
LINUS_1_0

The LINUS_1_0 directory contains an installation file called setup.py 
As root, run the following command in this directory: 

/path/to/your/python setup.py install 

This will install everything in your /path/to/your/python[version]/site-packages/ directory.  

After installing the LINUS distribution as described above add the following lines to your 
.cshrc (or .tcshrc, etc) file (with approriate editing for python version and path). 

setenv LINUS     '/usr/local/lib/python[version]/site-packages/pylinus_1_0' 
alias python    '/usr/local/bin/python[version]' 

Or if you use a .bash file: 

export LINUS = "/usr/local/lib/python[version]/site-packages/pylinus" 
alias python = '/usr/local/bin/python[version]'
