Gene and Protein families Tools

AUGUSTUS is a eukaryotic gene prediction tool. It can integrate evidence, e.g. from RNA-Seq, ESTs, proteomics, but can also predict genes ab initio. The PPX extension to AUGUSTUS can take a protein sequence multiple sequence alignment as input to find new members of the family in a genome. It can be run through a web interface (see https://bio.tools/webaugustus), or downloaded and run locally.

GAMMA (Gene Allele Mutation Microbial Assessment) is a command line tool that finds gene matches in microbial genomic data using protein coding (rather than nucleotide) identity, and then translates and annotates the match by providing the type (i.e., mutant, truncation, etc.) and a translated description.

Rapid genome-wide identification, annotation and analysis of secondary metabolite biosynthesis gene clusters in bacterial and fungal genomes. It integrates and cross-links with a large number of in silico secondary metabolite analysis tools that have been published earlier.

The purpose of CAFE is to analyze changes in gene family size in a way that accounts for phylogenetic history and provides a statistical foundation for evolutionary inferences. The program uses a birth and death process to model gene gain and loss across a user-specified phylogenetic tree. The distribution of family sizes generated under this model can provide a basis for assessing the significance of the observed family size differences among taxa.

Coinfinder (pronounced "coin-finder") is an algorithm and software tool that detects genes which associate and dissociate with other genes more often than expected by chance in pangenomes. Coinfinder is written primarily in C++ and is a command line tool which generates text, gexf, and pdf outputs for the user. Coinfinder uses a Bonferroni-corrected Binomial exact test statistic of the expected and observed rates of gene-gene association to evaluate whether a given gene pair is coincident.
