🌸 SMALT(1) β€” User Commands 🌸

okay bestie, sit down, hydrate, and let me tell you about smalt πŸ’… (that's the command name, and yeah, it's the star of this whole manual page, no notes)


✨ NAME ✨

smalt β€” Sequence Mapping and Alignment Tool πŸ‘‘


πŸ¦‹ DESCRIPTION πŸ¦‹

SMALT efficiently aligns DNA sequencing reads with a reference genome. fr fr, that's the whole vibe. It reads from a wide range of sequencing platforms β€” like, for example, Illumina, Roche-454, Ion Torrent, PacBio or ABI-Sanger β€” and paired reads can be processed too. multi-platform queen behavior πŸ’–

The software employs a perfect hash index of short words (< 20 nucleotides long), sampled at equidistant steps along the genomic reference sequences. it's giving very organized, very structured ✨

For each read, potentially matching segments in the reference are identified from seed matches in the index, and then those segments get aligned with the read using a banded Smith-Waterman algorithm. the alignment pipeline really said "let me cook" πŸ”₯

The best gapped alignments of each read is reported, and that includes a score for the reliability of the best mapping. and here's the fun part β€” you, yes YOU, can adjust the trade-off between sensitivity and speed by tuning the length and spacing of the hashed words. tuning your own destiny, lowkey iconic πŸŽ€

A mode for the detection of split (chimeric) reads is provided. also, multi-threaded program execution is supported. parallel processing? we love to see it πŸ’…

smalt <task> -H
need the tea on just one task? hit it with -H and it spills everything, no cap πŸ™ˆ

okay that's the whole page, bestie, you're basically a bioinformatics main character now πŸ‘‘
