For samples with a high fraction of non-host reads (ie stool samples), the .fasta outputs
following bowtie alignment may contain large numbers of sequences.
GSNAP alignment to NT and NR databases is a resource-intensive step.
Alignment to NT and NR databases is a resource-intensive step.
To reduce computational time, the reads are randomly sub-sampled to
1 million total fragments (1 million single-end reads or 2 million paired-end reads).

**kallisto RNA quantification**

Quantifies host transcripts using [kallisto](https://pachterlab.github.io/kallisto/about).
The host transcript sequences are sourced from GENCODE, along with
[ERCC control sequences](https://www.nist.gov/programs-projects/external-rna-controls-consortium).
Not all CZ ID host species have transcripts indexed; for those without, kallisto is run using ERCC
sequences only.
The host transcript sequences are sourced from GENCODE.
Not all CZ ID host species have transcripts indexed, so transcripts are not calculated for all hosts.
