Genetic variation Tools

BCFtools is a set of utilities that manipulate variant calls in the Variant Call Format (VCF) and its binary counterpart BCF. All commands work transparently with both VCFs and BCFs, both uncompressed and BGZF-compressed.

Bayesian genetic variant detector designed to find small polymorphisms, specifically SNPs, indels, multi-nucleotide polymorphisms, and complex events (composite insertion and substitution events) smaller than the length of a short-read sequencing alignment.

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.

The Genome Analysis Toolkit (GATK) is a set of bioinformatic tools for analyzing high-throughput sequencing (HTS) and variant call format (VCF) data. The toolkit is well established for germline short variant discovery from whole genome and exome sequencing data. GATK4 expands functionality into copy number and somatic analyses and offers pipeline scripts for workflows.

Inferring copy number alterations from tumor single cell RNA-Seq data

Computational tool to identify important genes from the recent genome-scale CRISPR-Cas9 knockout screens technology.

Optimized dynamic genome graph implementation: a toolkit for understanding pangenome graphs

Reference-free profiling of polyploid genomes | Inference of ploidy and heterozygosity structure using whole genome sequencing data | Smudgeplots are computed from raw or even better from trimmed reads and show the haplotype structure using heterozygous kmer pairs. For example: | This tool extracts heterozygous kmer pairs from kmer dump files and performs gymnastics with them. We are able to disentangle genome structure by comparing the sum of kmer pair coverages (CovA + CovB) to their relative coverage (CovA / (CovA + CovB)). Such an approach also allows us to analyze obscure genomes with duplications, various ploidy levels, etc | GenomeScope 2.0 and Smudgeplots: Reference-free profiling of polyploid genomes Timothy Rhyker Ranallo-Benavidez, Kamil S.

Snpeff is an open source tool that annotates variants and predicts their effects on genes by using an interval forest approach

Strelka is an analysis package designed to detect somatic SNVs and small indels from the aligned sequencing reads of matched tumor-normal samples.

ANNOVAR is an efficient software tool to utilize update-to-date information to functionally annotate genetic variants detected from diverse genomes (including human genome hg18, hg19, hg38, hs1 (T2T-CHM13) as well as mouse, worm, fly, yeast, SARS-CoV-2, and many others).

Library and software package for fast parsing and querying of VCF and BCF files and illustrate its speed, simplicity and utility.

Tool for predicting effects of variants for any genome in Ensembl or with genome annotation (via GFF). This includes vertebrates and also plants, fungi, protists, metazoa and bacteria.

FastANI is developed for fast alignment-free computation of whole-genome Average Nucleotide Identity (ANI). ANI is defined as mean nucleotide identity of orthologous gene pairs shared between two microbial genomes. FastANI supports pairwise comparison of both complete and draft genome assemblies.

LoFreq* (i.e. LoFreq version 2) is a fast and sensitive variant-caller for inferring SNVs and indels from next-generation sequencing data. It makes full use of base-call qualities and other sources of errors inherent in sequencing (e.g. mapping or base/indel alignment uncertainty), which are usually ignored by other methods or only used for filtering.

Fast, flexible annotation of genetic variants.
