INSTALL.md

1) 3ML and LiFF installation (only for Linux, not Mac yet):

3ML is a multi-wavelength/multi-messenger analysis framework that provides

a unified interface to software from many different instruments. It is

available as open-source code under: https://github.com/giacomov/3ML .

LiFF is the HAWC analysis software (compatible with 3ML) that is used to

study HAWC sky maps. It is available as open source code under:

https://github.com/rjlauer/aerie-liff .

Both frameworks can be installed via conda:

Install miniconda

wget -q https://repo.continuum.io/miniconda/Miniconda2-latest-Linux-x86_64.sh -O ~/miniconda.sh

This will install conda in ~/miniconda . If you want to put it somewhere else change accordingly these 3 lines

bash ~/miniconda.sh -b -p $HOME/miniconda export PATH="$HOME/miniconda/bin:$PATH"
source ~/miniconda/bin/activate

Create a test environment (to avoid playing with the root conda installation)

conda create --name hawc_test -y python=2.7

Activate environment

source activate hawc_test

install liff and threeml

conda install -c giacomov -c hawc -y liff threeml boost=1.61

#install mpmath package #(for convenient definition of inverse gamma function, used in cutoff-powerlaw integration) conda install mpmath

#for convenient environment loading, add to your login script: export PATH="$HOME/software/miniconda/bin:$PATH" source ~/software/miniconda/bin/activate source activate hawc_test export OMP_NUM_THREADS=1 export MKL_NUM_THREADS=1 export NUMEXPR_NUM_THREADS=1

#test: ipython import threeML

It should say:

Configuration read from /PATH/TO/.threeml/threeML_config.yml
