README

This python wrapper for MOOG allows you to use ewfind, blends (both non-interactive), synth and abfind drivers in an interactive way without the need for SuperMongo package. I kept the original MOOG layout, and added some minor improvements. You will find all MOOG source files in this repository (MOOG version from November 2019). All your MOOG's configuration files should work with this wrapper. For synth driver observed spectrum must be in text format (at least for now). To learn more about MOOG, visit Chris Sneden's webpage: MOOG

How do I get set up?

All MOOG source files are in this repository and will be downloaded automatically. If you have some MOOG version already installed, do not worry - those versions will not interact in any way.

The pyMOOGi was tested on Mac OS X and Linux machines. If you are a Windows user, sorry but you are on your own.

To use pyMOOGi you need gfortran to compile MOOG's sources and basic python libraries. If you are already familiar with python, you probably have them already installed.

For those who have never worked with python before: It is not necessary for you to know python to use pyMOOGi. You just need to have it working. If you have computer with Mac OS X or Linux, python is already there. It may be outdated, you will probably need to install libraries, but it is there. For easy updates and installing libraries I strongly recommend miniConda. Just follow the instructions and make sure that your .bashrc file or .profile file is properly configured.

For running pyMOOGi you will need:

• python3
• numpy
• scipy
• matplotlib
• make sure you can use matplotlib backend called 'qt5Agg' (if you decided to install python and its libraries with miniConda, this backend was installed automatically with matplotlib)

I have python set, what now?

• clone or download pyMOOGi from repository

• export path to moog directory:

  export MOOGPATH=/your/path/to/pymoogi/pymoogi/moog

Make sure that your system noticed those changes: check your .bashrc or .profile file, you should see MOOGPATH there. Do not forget to source your .bashrc, .profile, or eqiuvalent file.

• go to /your/path/to/pymoogi/pymoogi/moog
• run Makefile (just type make in terminal) - there might be some warnings, but at the end you should get an executable file called MOOG
• go to /your/path/to/pymoogi/ and run setup file:

python setup.py install

If you have more than one Python distribution and are unsure which one is the default one, run

python3 setup.py install

instead. This will point pyMOOGi to python3.

• now you are ready to run some calculations. Go to example catalog and type:

pymoogi synth_example.par

Issues

The most common issue with running pyMOOGi seems to be getting MOOG executable, especially for Mac OS X users. Please mind that I may not be able to help you with solving issues that are specific to your machine (like missing libraries, non-standard OS configurations, multiple versions of python etc.) that stop you from getting a MOOG executable.

My general tip for Mac OS X users: make sure that your XCode is up to date, having XCode Tools installed may also help.

For issues related to pyMOOGi - report an issue. Please use Issues tab at the top of pyMOOGi github page, and then start New issue.
