Conda Environments or Singularity Containers?

The following principles usually apply when deciding whether to use conda environments or Singularity containers.

Conda Environments:

• Best for R&D and changing workflows 
• Best to use to determine which tools work best and the order in which to string them in a workflow 
• Easy to create and use
• Less risk of duplication

Singularity Containers: 

• Better to use AFTER determining appropriate tools and staging with conda
• Can put conda environments inside singularity containers
• Provides better reproducibility
