Ultrafast universal spliced RNA-seq aligner based on sequential Maximum Mappable Prefix matching. High sensitivity for non-canonical splice junctions and chimeric gene fusions.
conda install -c bioconda star
Memory-efficient Burrows-Wheeler transform tool for aligning sequencing reads to long reference genomes. Ideal for ChIP-seq, ATAC-seq, and bacterial assemblies.
conda install -c bioconda bowtie2
Hierarchical Graph FM index aligner capable of mapping RNA-seq reads across population-scale variant graphs, reducing reference allele alignment bias.
conda install -c bioconda hisat2
Ultra-fast transcript abundance quantification from RNA-seq reads using quasi-mapping with GC-bias, sequence-specific bias, and fragment-length correction.
conda install -c bioconda salmon
Near-instantaneous pseudoalignment algorithm for quantifying transcript abundances from RNA-Seq reads by matching k-mers to colored de Bruijn graph paths without base-to-base alignment.
conda install -c bioconda kallisto
Haplotype-aware pangenome read aligner. Maps sequencing reads to variation graphs as fast as linear aligners, eliminating reference bias and uncovering structural alleles.

docker pull google/deepvariant:latest
Blazing-fast utility suite for calling, filtering, sorting, merging, and querying VCF/BCF variant call format files. Includes mpileup genotype caller and consensus builder.
conda install -c bioconda bcftools
Bayesian genetic variant detector designed to find SNPs, indels, MNPs, and complex haplotypes smaller than sequencing read length directly from short read alignments.
conda install -c bioconda freebayes
Fast and accurate structural variant caller for long reads (PacBio HiFi and Oxford Nanopore). Calls deletions, duplications, inversions, and translocations with multi-sample genotype calling.
conda install -c bioconda sniffles
Somatic and germline structural variant and indel caller for paired-end short reads. Combines discordant paired-end alignment evidence with split-read graph assembly.
conda install -c bioconda manta
Determines the clinical consequence of genomic variants in coding and non-coding regions. Annotates SIFT, PolyPhen, gnomAD allele frequencies, ClinVar, and splice sites.
conda install -c bioconda ensembl-vep
Rapid genomic variant annotation and functional effect prediction toolbox. Calculates consequence categories (missense, nonsense, frameshift) and filters multi-sample VCFs.
conda install -c bioconda snpeff
Integrated structural variant discovery tool utilizing paired-end discordant mapping and split-read clipping to resolve somatic and germline SV breakpoints at base-pair precision.
conda install -c bioconda delly
