NAME
MMseqs2 - MMseqs2 (Many against Many sequence searching): fast, parallelized protein sequence searches and clustering of huge protein sequence data sets.
SYNOPSIS
mmseqs <module> args
DESCRIPTION
MMseqs2 (Many-against-Many sequence searching) is a software suite to search and cluster huge proteins/nucleotide sequence sets. MMseqs2 is open source GPL-licensed software implemented in C++ for Linux, MacOS, and (as beta version, via cygwin) Windows. The software is designed to run on multiple cores and servers and exhibits very good scalability. MMseqs2 can run 10000 times faster than BLAST. At 100 times its speed it achieves almost the same sensitivity. It can perform profile searches with the same sensitivity as PSI-BLAST at over 400 times its speed. The following depicts the different <module> that can be used. Easy workflows (for non-experts) An example for running a command using easy-* modules would be mmseqs easy-search <DB> <targetDB> easy-search Search with a query fasta against target fasta (or database) and return a BLAST-compatible result in a single step easy-linsearch Linear time search with a query fasta against target fasta (or database) and return a BLAST-compatible result in a single step easy-linclust Compute clustering of a fasta/fastq database in linear time. The workflow outputs the representative sequences, a cluster tsv and a fasta-like format containing all sequences. easy-cluster Compute clustering of a fasta database. The workflow outputs the representative sequences, a cluster tsv and a fasta-like format containing all sequences. easy-taxonomy Compute taxonomy and lowest common ancestor for each sequence. The workflow outputs a taxonomic classification for sequences and a hierarchical summery report.
