BWA-MEM2 vs. Minimap2: Short-Read vs. Long-Read Alignment
Choosing between FM-index exact matching and minimizer-based approximate seed chaining.
| Feature / Metric | BWA-MEM2 | Minimap2 | Recommendation |
|---|---|---|---|
| Core Algorithm | FM-index + SIMD AVX-512 acceleration | Minimizer sketch + Seed-and-extend chaining | BWA-MEM2 for short reads; Minimap2 for long reads |
| Ideal Read Length | 70 bp – 300 bp (Illumina / MGI / Element) | 1 kb – 100 kb+ (Nanopore, PacBio, Assembly) | Use Minimap2 for ONT / PacBio; BWA-MEM2 for Illumina |
| RAM Requirement | ~32 GB RAM (Human GRCh38) | ~8 – 14 GB RAM (Human GRCh38) | Minimap2 is significantly lighter on memory |
| Speed & Throughput | 3.5× faster than original BWA-MEM | Ultra-fast; maps 30× ONT genome in < 2 hrs | Both utilize modern multi-core SIMD scaling |
| Structural Variant / CIGAR | Hard/soft clipping, limited large indel detection | Long-gap penalties, excels at large SV indels | Minimap2 essential for structural variant discovery |
| GATK Best Practices | Official gold standard for germline/somatic pipelines | Supported via -ax sr, but less standard for short reads | Use BWA-MEM2 for clinical Illumina variant calling |
