Download the raw and processed error rate sequencing data, at least until it is sent to the SRA. This tar file contains one directory for each sample of the data. In each directory are xz-compressed copies of the raw reads with symbolic links to r1.fastq.xz and r2.fastq.xz. The outputs from the various steps performed by the error rate preprocessing tools are included as the set of files with prefixes step1, step2, step3, and step4. The Rerrrt package reads the final files using the sample sheet: all_samples.xlsx in order to associate the samples with their IDs and metadata.
