A growing toolbox of one-click operations on sequence files. Paste or upload your data, pick an operation below, and the result appears in the Result tab ready to copy or download.
Operations work on plain sequence (FASTA, tab-delimited "name sequence", or a single bare sequence) and clean every record to IUPAC letters first. File formats, annotations & reads works on the file as written — it reads FASTA, FASTQ, GenBank, EMBL, Clustal, PHYLIP and NEXUS, detects which one you pasted, and keeps headers, gaps, quality strings and feature tables intact.
More transforms will be added here over time — each is independent, so this list will keep growing.
Unlike the operations above, everything in this card reads the file exactly as written — headers, gaps, quality strings and feature tables are preserved rather than stripped. The input format is detected automatically; override it only when the guess is wrong.
Output options
Spliced join(…) and complement(…) locations are assembled correctly, and a translation is checked against the record's own /translation.
Phred+33 and Phred+64 encodings are detected automatically. The report covers per-position quality and base composition, read-length distribution, duplication and an adapter screen.
