okay bestie, sit down, hydrate, and let me tell you about smalt π
(that's the command name, and yeah, it's the star of this whole manual page, no notes)
β¨ NAME β¨
smalt β Sequence Mapping and Alignment Tool π
π¦ DESCRIPTION π¦
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 π
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 β¨
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" π₯
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 π
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 π

smalt <task> -H
need the tea on just one task? hit it with -H and it spills everything, no cap π
okay that's the whole page, bestie, you're basically a bioinformatics main character now π
this was smalt 0.7.6, dated April 2014 β shoutout to the source and version, they ate and left no crumbs πβ¨π§¬
