Singularity Recipe

Bootstrap: docker
From: continuumio/miniconda3

# This file is a singularity definition file to create simg with conda
# It starts with a docker image of miniconda continuumio/miniconda3
# It allows direct creation of the env by specifying which package (or with a .yml file)
# unlock desired method by removing # and set variable (defname) or file name (xxxx.yml) 
# future dev: if else, yml or package names as argument for $ singularity build command
# Image build with ($ sudo singularity build imagename.simg Singularity )
