Eggnog Mapper
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
EggNOG-mapper is a bioinformatics tool designed for fast and accurate functional annotation of novel sequences, primarily proteins. It leverages precomputed orthologous groups from the EggNOG database to assign functional annotations, such as gene ontology terms, KEGG pathways, and annotations of conserved domains, to input sequences efficiently. Its primary use is in genome annotation pipelines to facilitate understanding the biological roles of genes in various organisms.
Key Features
- Utilizes comprehensive EggNOG database for orthologous group assignments
- Provides rapid functional annotation of protein sequences
- Supports multiple types of annotations including gene ontology, KEGG, Pfam domains
- Command-line interface suitable for high-throughput analysis
- Compatible with various operating systems and integrable into bioinformatics pipelines
- Includes optional parameters for customized annotations and thresholds
Pros
- High speed and efficiency in annotating large datasets
- Accurate functional predictions through orthology-based methods
- Extensive support for various annotation categories
- Well-maintained and regularly updated with rich comparative data
- Open-source and freely available to academic users
Cons
- Requires some familiarity with command-line tools
- Dependent on the quality and coverage of the EggNOG database; less effective for very novel or poorly characterized proteins
