Installation instructions
Note: You are viewing an old revision of this page. View the current version.
The following packages might be missing in your Linux distribution and are needed by tsscds. The lines below show the mechanism to download and install such packages in Ubuntu:
sudo apt update
sudo apt install bc environment-modules gawk gcc gfortran parallel python-numpy python-scipy sqlite3 zenity
Besides, to analyze the results it is very convenient to install gnuplot and molden.
Finally, 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
Once the above packages are installed, go to the tsscds-SOURCE-2018 folder 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, use :
./configure --prefix=path_to_program
Finally, complete the installation:
make
make install
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)
