Description

A TAB-delimited file to describe samples and paired-end FASTQ files associated with them. By doing so, this file type links sample names to raw sequencing reads.

This file type includes required and optional columns.

The following three columns are required for this file type:

  • sample: a single-word sample name,
  • r1: path to the FASTQ file for pair one, and
  • r2: path to the FASTQ file for pair two.

While you can use relative paths for r1 and r2, it is always better to have absolute paths to improve reproducibility.

The following is an optional column:

  • group: A single-word categorical variable that assigns two or more samples into two or more groups. This is useful to co-assemble multiple samples so that you can bin them later.

For more information, see the anvi’o workflow tutorial
