Marker
Bacteria & Archaea

Paste a full-length rRNA sequence (50-5000 bp). Predictions are returned across all eight taxonomic ranks with confidence scores. Try a Bacterial example.

Limit sample size Off by default — all reads in the file are processed. Turn on to cap how many reads to process (e.g. a faster preview).
Skip adapter trimming Adapter trimming now runs automatically when ONT adapter signatures are detected in more than 5% of sampled reads. Enable this only if your reads are already adapter-trimmed.
Minimum quality (FASTQ only) Phred score threshold. 0 disables filtering. 7 is the permissive Nanopore default.

Custom length filter Off by default — reads are filtered to the marker's validated window (16S 1,200–2,000 bp, ITS 300–1,000 bp). Turn on to set your own range.

Skip adapter trimming Adapter trimming runs automatically for each sample when ONT adapter signatures are detected in more than 5% of sampled reads. Enable this only if your reads are already adapter-trimmed.
Limit sample size Off by default — all reads in every sample are processed. Turn on to cap how many reads per sample.
Custom length filter Off by default — every sample is filtered to the marker's validated window (16S 1,200–2,000 bp, ITS 300–1,000 bp). Turn on to set your own range.
