N.B. The versions of pangolin and nextclade are indicated in the footer of this report. Because of the fast moving nature of the pandemic these versions may not be the most recent, but we check daily for new versions. More details are provided here.

Read Quality control

This section displays basic QC metrics indicating read data quality.

Sequence summaries

Artic Analysis status

The panel below lists samples which failed to produce results from the primary ARTIC analysis. Samples not listed here were analysed successfully, but may still contain inconclusive or invalid results. See the following sections for further indications of failed or inconclusive results.

All samples analysed successfully

Genome coverage

Plots below indicate depth of coverage from data used within the Artic analysis coloured by amplicon pool. Variant filtering during the ARTIC analysis mandates a minimum coverage of at least 20X at variant/genotyping loci for a call to be made.

NB: To better display all possible data, the depth axes of the plots below are not tied between plots for different samples. Care should be taken in comparing depth across samples.

Variant call summaries

The following tables and figures are derived from the output of bcftools stats.

Variant counts:

sample MNPs SNPs indels multiallelic SNP sites multiallelic sites no-ALTs others records
barcode01.pass.named.stats 0 7 0 0 0 0 0 7
barcode02.pass.named.stats 0 7 0 0 0 0 0 7

Transitions and tranversions:

sample ts tv ts/tv ts (1st ALT) tv (1st ALT) ts/tv (1st ALT)
barcode01.pass.named.stats 6 1 6.00 6 1 6.00
barcode02.pass.named.stats 6 1 6.00 6 1 6.00

Substitution types

Base substitutions aggregated across all samples (symmetrised by pairing)

Indel lengths

Insertion and deletion lengths aggregated across all samples.

No indels to report.

NextClade analysis

The following view is produced by the nextclade software.

The table shows errors, warnings or failed genes per sample:

index Sample Name clade Failed CDS Warnings Errors
0 barcode01 MN908947.3 20C None None None
1 barcode02 MN908947.3 20C None None None
