DRAGEN Targeted Microbial

Details:

This app is designed to analyze sequencing libraries generated from Illumina hybrid capture (enrichment) panels or tiled amplicon panels (ie COVIDseq).

Analysis Pipeline

Reads are trimmed and filtered using Trimmomatic with the following parameters: LEADING:3 TRAILING:3 SLIDINGWINDOW: 4:15 MINLEN:36.
Human reads are removed with a modified version of the SRA Human Read Scrubber tool.
MEGAHIT is used to perform de novo assembly on the scrubbed reads.
CD-HIT-EST is used to cluster similar contigs to reduce redundancy.
The resulting contigs are mapped to a set of reference genomes using minimap2.
The best matching reference for each contig is selected for short read mapping.
The scrubbed reads from step 3 are aligned to the selected reference genomes using [DRAGEN v4.0.3]
Sequence variants are called from the alignments using DRAGEN Somatic v4.0.3 and applied to the corresponding reference sequences to create consensus sequences.
If applicable, Pangolin and/or Nextclade are run on the consensus sequences.

Outputs

The software generates sequences representing a best estimate of the population of targeted sequences in the sample. NextClade and Pangolin analysis are run on select organisms. Output details in output txt file.
