Mega Limited

iGEM is the computational biology division of Temple University’s Institute for Genomic Evolutionary Medicine, focused on turning raw DNA, RNA and protein sequences into publishable evolutionary insight. Its single, long-standing product line—Molecular Evolutionary Genetics Analysis—distills three decades of academic algorithm development into an integrated desktop suite that handles everything from multi-sequence alignment and phylogenetic reconstruction to positive-selection scans and molecular-clock dating. Researchers typically import FASTA or GenBank files, clean and translate them with built-in codon tables, then choose among maximum-likelihood, parsimony or distance-based methods to build trees annotated with bootstrap or Bayesian support. Population geneticists use the same workspace to compute Tajima’s D, FST, dN/dS or neutrality tests on thousands of genomes, while epidemiologists exploit the time-scaled tree module to visualize outbreak trajectories. A lightweight GUI wizard keeps the workflow approachable for graduate students, yet command-line binaries and R-conduit libraries let bioinformaticians script large comparative studies on clusters. MEGA12, the current release, adds GPU acceleration for phylogenies exceeding 50 000 taxa and live alignment streaming from NCBI Virus. All packages are available free of charge on get.nero.com, where downloads are delivered through trusted Windows sources such as winget, always installing the newest build and supporting unattended batch deployment of multiple applications.
