Mothur is an open source software package for bioinformatics data processing. The package is frequently used in the analysis of DNA from uncultured microbes.

Motif - Graphical user interface GUI specification and the widget toolkit.

The mOTU profiler is a computational tool that estimates relative taxonomic abundance of known and currently unknown microbial community members using metagenomic shotgun sequencing data.

Gnu Mpc is a C library for the arithmetic of complex numbers with arbitrarily high precision and correct rounding of the result.

The MPFR library is a C library for multiple-precision floating-point computations with correct rounding.

MrBayes is a program for Bayesian inference and model choice across a wide range of phylogenetic and evolutionary models. MrBayes uses Markov chain Monte Carlo (MCMC) methods to estimate the posterior distribution of model parameters.

Multiqc is a reporting tool that parses summary statistics from results and log files generated by other bioinformatics tools.

Mummer4 is a versatile alignment tool for DNA and protein sequences.

Muscle is a modified progressive alignment algorithm which has comparable accuracy to MAFFT, but faster performance.

MutMap is a powerful and efficient method to identify agronomically important loci in crop plants.

Mvapich2 is a High-Performance MPI Library for clusters with diverse networks InfiniBand, Omni-Path, Ethernet/iWARP, and RoCE and computing platforms x86 Intel and AMD, ARM and OpenPOWER.

Mykrobe analyses the whole genome of a bacterial sample, all within a couple of minutes, and predicts which drugs the infection is resistant to.

N50 is a command line tool to calculate assembly metrices.

NAMD is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. NAMD uses the popular molecular graphics program VMD for simulation setup and trajectory analysis, but is also file-compatible with AMBER, CHARMM, and X-PLOR.

Nanofilt is a tool for filtering and trimming of Oxford Nanopore Sequencing data.

Nanolyse is a tool to remove reads mapping to the lambda phage genome from a fastq file.

Nanoplot is a plotting tool for long read sequencing data and alignments.

Nanopolish is a software package for signal-level analysis of Oxford Nanopore sequencing data.

NCBI Datasets is a new resource that lets you easily gather data from across NCBI databases. You can use it to find and download sequence, annotation, and metadata for genes and genomes using our command-line interface (CLI) tools or NCBI Datasets web interface.

Ncbi-amrfinderplus and the accompanying database identify acquired antimicrobial resistance genes in bacterial protein and/or assembled nucleotide sequences as well as known resistance-associated point mutations for several taxa.
