====================INSTALLATION INSTRUCTIONS==============================
Untar and unzip the file tsscds-SOURCE-2018.tar.gz:

	tar xvfz tsscds-SOURCE-2018.tar.gz

Before installing tsscds, be aware that the following packages are needed:

bc, environment-modules, gawk, gcc, gfortran, parallel, python-numpy, python-scipy, sqlite3, zenity

You can install the missing ones manually, or you can try any of the scripts:

install-required-packages-distro.sh (where distro=ubuntu-16.4lts, centos7 or sl7), which will do the work for you.

The ubuntu-16.4lts script installs all dependencies, but for the RHEL derivatives (centos7 and sl7) you have two choices to install parallel:
a) install-gnu-parallel-from-source.sh. This script installs parallel latest version from source thanks to Ole Tange (the parallel author). Also it can fallback to a user private installation into $HOME/bin if you have not administrator permisions to install it globally.
b) install-gnu-parallel-from-epel.sh. Enables the EPEL repository and installs parallel from it.

To use any of the above scripts, first go to the tsscds-SOURCE-2018 folder:

       cd tsscds-SOURCE-2018

The program runs using two levels of theory: semiempirical (or Low-Level LL) and ab initio/DFT (or High-Level HL). So far, the only program interfaced with tsscds to perform the ab initio/DFT calculations is G09. Therefore, if you want to perform the HL calculations G09 should be installed and should run like in this example: g09<inputfile>outputfile
These packages might also be useful to analyze the results:

gnuplot, molden, sqlitebrowser

Once the above packages are installed, go to the tsscds-SOURCE-2018 folder (if you are not already there) to configure and install the package:

	cd tsscds-SOURCE-2018

	./configure

This will install tsscds2018 in $HOME/tsscds-2018 by default. If you want to install it in a different directory, type:

./configure --prefix=path_to_program

Finally, complete the installation:

	make
	make install
	make clean

The last command (make clean) is only necessary if you want to remove from the src directory the object files and executables created in the compilation process.

For convenience, and once “Environment Modules” has been installed, you can add to your .bashrc file the following line to use the tsscds module:

module use path_to_program/modules

where path_to_program is the path where you installed tsscds (e.g., $HOME/tsscds-2018).


THIS IS JUST FOR DEVELOPERS:
-run 'autoreconf -i' after svn check out

====================PROGRAM EXECUTION======================================
To start using any of the scripts of the program, you have to load tsscds/2018 module:

	module load tsscds/2018

Then, please follow the instructions given in the tutorial, which can be found in: 
tsscds-SOURCE-2018/docs/tutorial.pdf  or
path_to_program/doc/tutorial.pdf
