Study Notes
Criteria for a Good Tool
- Accurate and reproducible results in a reasonable format
- Suitable for specific application
- Computationally efficient and scalable
- User-friendly with explanatory error messages
- Easy installation
- Widely used in the community
- Well-supported and infrequently updated
Installation of Software
- 51% of 98 software tools tested were "easy to install"
- 28% of tools failed to install
- Package managers like Conda make installation easier
- Containerized software (e.g. Docker, Singularity) allows for reproducibility and ease of use
Containerized Software
- Allows for exact same code to be applied on different machines
- Holds a minimal Linux operating system with necessary dependencies
- Commands and Workflows can be run within containers with minimal intrusion from user operating system
- Enables reproducibility and ease of analysis
Workflow Software
- Reduces development time, improves efficiency, and aids reproducibility
- Allows for effective monitoring and restarting of analyses
- Examples of workflow languages include Snakemake (implemented in Python) and Nextflow
Limitations of Containers
- Large metagenomic databases can be too large to include in containers
- Containers can be difficult to update and require sourcing original build recipe
- Containers can rely on Internet access, which can hinder reproducibility
Tool Performance
- Reading tool manuscripts is not always the best way to gauge their performance
- Independent benchmarking approaches can help determine which tool is best for specific circumstances
- Examples of tools include Kraken, BRACKEN, mOTUs2, and MetaPhlAn
Taxonomic Profilers
- Kraken is a widely used tool for taxonomic classification
- Kraken allows for user-defined metagenomic databases
- Drawbacks of Kraken include false positive results and high memory requirements
- Other taxonomic profilers include mOTUs2, MetaPhlAn, and BRACKEN
