First release of ELF_AnalyserAndPlot This program plots on a graph the electronic variations around the atoms along an IRC calculation of a chemical reaction. From the out files generated by ELF calculation, that contain information about geometry, basin and values of them. Features: Extract geometry of atoms and basins from the out-files generated; Extract values for each basin; Create association between basin/s and atom/s; Divide in different files the interactions between atoms and values in each point; Clean useless interaction (the ones that don't suffer variations); Plot with lines the values in a graph, giving different options about the elaboration. How to install: Use the installer "install.sh" and follow the instruction. For manual installation create a folder, paste inside all files and create an alias that executes "main.sh" from that folder then insert an environmental variable writing: export EAAPpath="here the path where find files". Anyway, you can find more informations reading inside install.sh. How to use: Run the alias you setted up (whether you used the automatic installer or you did it manually) into a folder that contains the out-files generated from ELF calculation. The name of the file have to be with a part of your choosing, after this a dash and the progressive number from 1 to the last step (without interruptions) and after the number an underscore and the word "elf" example: "name you prefer"-"number"_elf.out
