Methods
Data were processed with the IoSCore components FileSource 0.2.0 (filePath = data/experimental/fasta/00010.fasta, chunkSize = 65536; 1 out), then FASTAReader 0.2.0 (strict = true; 1 in, 10 out), then SequenceLengths 0.1.0 (default parameters; 10 in, 10 out), then TableArtefact 0.1.0 (title = Sequence lengths, caption = Length of every sequence in the input.; 10 in), then FigureArtefact 0.1.0 (title = Length distribution, type = histogram, x = length, bins = 10, width = 640, height = 400; 10 in), using IoSCore 0.3.0 on Node v20.19.1 (darwin arm64), run on 2026-10-25T11:28:10.059Z. Input: data/experimental/fasta/00010.fasta. Element types were validated at every component boundary (sample, 4 elements).
