# Release notes

#### DRAGEN Microbial Enrichment Plus app version 1.1.0

**Component versions**

  * RVOP 2.7.0
  * VSP 2.7.0
  * VSPv2 2.7.0
  * Custom 1.0.0
* Analysis Pipeline version: 6.3.12
* DRAGEN version: 4.3.11

**Third-party versions**

* Pangolin 4.3.1 (Pangolin database PUSHER version 1.27)
* Nextclade 3.5.0
* SnpEff 5.1
* ResFinder (version 2.2.1)
* NCBI Reference Gene Catalog (version 2023-09-26.1)
* EUCAST expert rules on indicator agents (2019-2023)
* CLSI Performance Standards for Antimicrobial Susceptibility Testing (M100 34th Edition)
* Comprehensive Antibiotic Research Database (CARD, version 3.2.8)
* Comprehensive Antibiotic Research Database Prevalence Data (CARD Prevalence, version 4.0.1)
* World Health Organization (WHO) Influenza virus neuraminidase inhibitor (NAI) and polymerase acidic protein inhibitor (PAI) Reduced Susceptibility Marker Tables (07 March 2023 version)

**Key updates**

* Various bug fixes (see below)
* Tiered reporting added for Norovirus (GI, GII, GIV, GVIII, GIX) and Dengue virus (type 1, type 2, type 3, type 4)
* Tiered reporting suppressed for below subtype resolution of Influenza A virus subtypes H1N1 and H3N2
* Nextclade datasets added for Measles virus (MV) and Dengue virus (DENV) clade assignment
* Reference genomes added for Monkeypox virus (MPV) Clade 1b
* Additional database curation

**Known issues**

* When reading Biosamples from a Project, Fastq files for Biosamples sharing the same sample name prefix before the first underscore are merged. For example, Fastq files for Biosamples PREFIX\_001 and PREFIX\_002 will be merged and reported as a single PREFIX sample. To avoid this error, ensure that sample names are unique before the first underscore, replace underscores with a hyphen, or provide Biosample input from a list
* Coverage results for SARS-CoV-2 are slightly (<1%) over-estimated, which may result in coverage >100% due to an error accounting for masked polyA-tail bases
* Viral genome consensus sequence bases without aligned read support are indicated by "X" bases rather than "N" bases for RPIP viruses except SARS-CoV-2 and Influenza viruses
* Variant annotation information for Influenza A and B viruses, including antiviral resistance prediction results, may not be populated when below threshold reporting is enabled and/or a user-defined microorganism reporting file is specified that does not include all members of the Influenza A and B virus tiered reporting groups. If viral variant annotation is of interest for Influenza A and B viruses, default microorganism reporting options are recommended

**Known limitations**

* When providing Biosample input from a list, 99 associated Fastq files is the maximum allowed per analysis. There is no Fastq file limitation when reading Biosamples from a Project
* In strains containing insertion-deletion mutations (indels), there is a risk of false positive or false negative results for other resistance mutations within a region of 100 nucleotides around the indel
* In strains containing long insertion-deletion mutations (indels), there is a risk of false negative results for two large vAMR-associated deletion mutations (RPIP, VSPv2) and one large bAMR-associated insertion mutation (RPIP). Long indels may be incorrectly reported as other variant types, such as frameshift mutations
* Small differences in SARS-CoV-2 and Influenza virus results may be observed between repeat analyses

**Bug fixes**

* Nextclade parsing errors for some samples
* Custom reference sequence analysis not functional in non-US regions
* User-defined microorganism reporting feature not reporting microorganisms that belong to a tiered reporting group when “prediction\_logic” column set to “default”
* RPKM and absolute quantity metrics inaccurate when read QC disabled
* SHV beta-lactamase AMR markers incorrectly reported as carbapenemases based on a known curation error in CARD version 3.2.8
* Reads duplicated for samples with a single FASTQ file
* Empty FASTQ files abort analysis
* Pangolin not run on all samples with SARS-CoV-2 detected
* Viral genome coverage plots not rendered for segmented viruses when all segments not detected
* Description information missing for some viral genome accessions

**Known issues**

* When reading Biosamples from a Project, Fastq files for Biosamples sharing the same sample name prefix before the first underscore are merged. For example, Fastq files for Biosamples PREFIX\_001 and PREFIX\_002 will be merged and reported as a single PREFIX sample.

* Reads are duplicated for samples with a single FASTQ file
* Empty FASTQ files will abort analysis
* Nextclade may encounter a parsing error for some samples. If an analysis fails, try re-running the analysis with Nextclade disabled
* Pangolin may not be run on all samples with SARS-COV-2 detected
* Custom reference sequence analysis is not functional in non-US regions
* The user-defined microorganism reporting feature does not report microorganisms that belong to a tiered reporting group when the “prediction\_logic” column is set to “default”. See the User Guide for further information about microorganism tiered reporting
* RPKM and absolute quantity metrics are inaccurate when read QC is disabled
* SHV beta-lactamase AMR markers are incorrectly reported as carbapenemases based on a known curation error in CARD version 3.2.8

Long indels may be incorrectly reported as other variant types, such as frameshift mutations
* The RPIP, VSPv2, VSPv1, and RVOP Data Analysis solutions can report Influenza A virus subtypes H1N1 and H3N2 to a below-subtype resolution. Multiple results for H1N1 and/or H3N2 may be reported concurrently, particularly in samples that contain a mixture of Influenza A virus subtypes
* Viral genome coverage plots are not rendered for segmented viruses when all segments are not detected
* Description information is missing for some viral genome accessions
