xlavir 0.5.1

Excel report from viral sequencing analysis output

xlavir

Excel report from viral sequencing data analysis output from the nf-core/viralrecon or peterk87/nf-virontus Nextflow pipelines.

• Free software: MIT license

• Documentation: https://xlavir.readthedocs.io.

Features

• Collect sample results from a nf-core/viralrecon or peterk87/nf-virontus into a Excel report

  • Samtools read mapping stats (flagstat)

  • Mosdepth read mapping coverage information

  • Variant calling information (SnpEff and SnpSift results, VCF file information)

  • Consensus sequences

• QA/QC of sample analysis results (basic PASS/FAIL based on minimum genome coverage and depth)

• Nextflow workflow execution information

• Prepend worksheets from other Excel documents into the report (e.g. cover page/sheet, sample sheet, lab results)

• Add custom images into worksheets with custom names and descriptions (e.g. phylogenetic tree figure PNG)

Roadmap

• Bcftools variant calling stats sheet

• Sample metadata table to merge with certain stats?

• YAML config to info sheet?

• coverage chart with controls?

History

0.5.1 (2021-08-04)

• Fixed issue (#12) where iVar ref allele depth corresponds to depth of base before deletion. For indels, ref allele depth is taken from the total depth minus the alt allele depth.

• Fixed issue (#14) where the total number of reads from samtools flagstat may not be the true number of reads. The unmapped reads may be excluded from the BAM file so the samtools flagstat total number of reads may be equal to the number of mapped reads. There is now a search for fastp JSON files to get the true total number of reads.

0.5.0 (2021-07-30)

• Added support for Nanopolish VCF parsing as generated by the ARTIC pipeline

• Added deduplication of VCF and SnpSift entries since the ARTIC pipeline may produce VCF files with duplicate variant calls due to overlap between amplicons.

• Added VCF and SnpSift test data for CLI test to generate Excel report.

0.4.3 (2021-07-29)

• Fix an issue where single base positions are being reported as 0-based when all other ranges are 1-based for reporting of low/no coverage regions from Mosdepth per-base BED files (#10).

0.4.2 (2021-05-21)

• Add support for nf-core/viralrecon version 2.0 (requires Mosdepth bed.gz files be output; needs custom modules.config like this one)

• Nextclade CLI per sample results parsed into sheet showing useful info like Nextstrain clade, # of mutations, # of PCR primer changes

• Added check that input directory exists and is a directory

• Added sheet with xlavir info

• Added Gene, Variant Effect, Variant Impact, Amino Acid Change to Variant Summary table

0.4.1 (2021-05-14)

• Add reference sequence length to QC stats table. Get ref seq length from max mosdepth per base BED coverage value.

• Add more conditional formatting

• Fix execution_report.html finding

• Fix version printing; add to help

• Add epilog with usage info

0.4.0 (2021-04-23)

• Adds “Variants Summary” sheet summarizing variant information across all samples

• Adds comments to AF values in “Variant Matrix” sheet

• Fixes width/height of cell comments to be based on length of comment text

0.3.0 (2021-04-23)

• Adds support for adding Ct values from a Ct values table (tab-delimited, CSV, ODS, XLSX format) into an xlavir report.

0.2.4 (2021-04-19)

• Fixes issue with SnpSift table file parsing and variable naming in variants.py (#4, #5)

0.2.3 (2021-04-19)

• Fixes issue with SnpSift table file parsing. Adds check to see if SnpSift column is dtype object/str before using .str Series methods (#4)

0.2.2 (2021-03-30)

• Fixes issue with SnpEff/SnpSift AA change parsing.

0.2.1 (2021-03-29)

• Fix division by zero error due to variants with DP values of 0

0.2.0 (2021-03-04)

• Added header comments with descriptions of field content

• Added comment to Variant Matrix sheet A1 cell describing what is shown in the matrix

• Added highlighting of samples failing QC in other sheets

• Fixed image scaling by determining image size with imageio

• Added Medaka / Longshot VCF parsing

0.1.1 (2021-02-16)

• Collect sample results from a nf-core/viralrecon or peterk87/nf-virontus into a Excel report

  • Samtools read mapping stats (flagstat)

  • Mosdepth read mapping coverage information

  • Variant calling information (SnpEff and SnpSift results, VCF file information)

  • Consensus sequences

• iVar VCF parsing

• QA/QC of sample analysis results (basic PASS/FAIL based on minimum genome coverage and depth)

• Nextflow workflow execution information
