Transpose locus alignments into per-sample sequence files. Locus alignments store one locus per file with a sequence for each sample. Transposing creates one file for each sample with a sequence for each locus, for example to build sample-level references for read mapping.
- Select

Output
Section titled “Output”The app writes each sample to its own folder: <sample>/<sample>.fas. Each sequence is named after the locus it comes from, which is the input file name without its extension. Gaps (-) and missing data (?) are removed, so the output is always unaligned FASTA. Samples missing from a locus are skipped for that locus.
