GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating-point numbers.

GMT Generic Mapping Tools is an open source collection of about 80 command-line tools for manipulating geographic and Cartesian data sets including filtering, trend fitting, gridding, projecting, etc. and producing PostScript illustrations ranging from simple x-y plots via contour maps to artificially illuminated surfaces and 3D perspective views.

The GNU Scientific Library GSL is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite.

The Grid Analysis and Display System (GrADS) is an interactive desktop tool that is used for easy access, manipulation, and visualization of earth science data. GrADS has two data models for handling gridded and station data.

Graphlan is a software tool for producing high-quality circular representations of taxonomic and phylogenetic trees.

Graphmap is a novel mapper targeted at aligning long, error-prone third-generation sequencing data.

Gridss is a module software suite containing tools useful for the detection of genomic rearrangements.

GROMACS is a molecular dynamics application designed to simulate Newtonian equations of motion for systems with hundreds to millions of particles. GROMACS is designed to simulate biochemical molecules like proteins, lipids, and nucleic acids that have a lot of complicated bonded interactions.

Gseapy is a python wrapper for GESA and Enrichr.

GTDB-Tk is a software toolkit for assigning objective taxonomic classifications to bacterial and archaeal genomes based on the Genome Database Taxonomy GTDB. It is designed to work with recent advances that allow hundreds or thousands of metagenome-assembled genomes (MAGs) to be obtained directly from environmental samples. It can also be applied to isolate and single-cell genomes.

Gubbins is an algorithm that iteratively identifies loci containing elevated densities of base substitutions while concurrently constructing a phylogeny based on the putative point mutations outside of these regions.

Guppy is a data processing toolkit that contains the Oxford Nanopore Technologies? basecalling algorithms, and several bioinformatic post-processing features.
