V-pipe configuration

Type: object

The V-pipe workflow can be customized through the configuration file config.yaml or config.json or, for backward compatibility with the legacy INI-style format used in V-pipe v1.x/2.x, vpipe.config. This configuration file is a text file written using a basic structure composed of sections, properties and values. When using YAML or JSON format use these languages associative array/dictionaries in two levels for sections and properties. When using the older INI format, sections are expected in squared brackets, and properties are followed by corresponding values.

Further more, it is possible to specify additional options on the command line using Snakemake’s --configfile to pass additional YAML/JSON configuration files, and/or using Snakemake’s --config to pass sections and properties in a YAML Flow style/JSON syntax.

The order of precedence is:
command line options (--config, --configfile) >> default configuration file (config/config.yaml or config.yaml) >> legacy configuration INI (vpipe.config) >> Virus-specific base config (virus_based_config) >> default values

Example: For instance, we suggest providing as input a tabular file specifying sample unique identifiers (e.g., patient identifiers), and dates for different sequencing runs related to the same patient. The name of this file (here, samples.tsv) can be provided by specifying the section as input and the property as samples_file, as follows in the example below.

In this document, we provide a comprehensive list of all user-configurable options stratified by sections.


Example:

input:
-  samples_file: samples.tsv
-

Type: object Default: {}

This section of the configuration provides general options that control the overall behavior of the pipeline.

Type: string Default: ""

We provide virus-specific base configuration files which contain handy defaults for, e.g., HIV and SARS-CoV-2. Check the git repository’s config subdirectory to learn about them.


Examples:

hiv
-
sars-cov-2
-

Type: enum (of string) Default: "prinseq"

By default trimming and clipping of reads is performed by PRINSEQ 1 – a versatile raw read processor for short-reads with many customization options, that we use mostly for Illumina short-read sequencing.
Some other sequencing platforms, e.g., Oxford Nanopore Technologies, are not compatible with this software and usually perform quality control during the fast5 basecalling and demultiplexing anyway, e.g., by Guppy. Use skip to avoid performing preprocessing such already quality-trimmed fastq files.

-

Type: enum (of string) Default: "ngshmmalign"

There are three options for mapping reads, either using ngshmmalign, BWA MEM (bwa) 1, Bowtie 2 (bowtie) 2, or minimap2 (minimap)3. To use a different aligner than the default, indicate which aligner you want to use by setting the property aligner.

Note: Some virus-specific base configuration specified in virus_base_config might change this option’s default to a more appropriate aligner for that virus, e.g., depending on its usual diversity and mutation rate.
You are still free to override that default in your configuration shall the need arise.

-

Type: string Default: ""

Some step of V-pipe produce temporary files such as, e.g., decompressed intermediate — i.e. files which aren’t kept long-term but are deleted after all steps that needed them have finished. By default, these files are written in the output data directory. This option, makes it is possible to write them in a different directory instead. Use this option to, e.g., leverage a faster cluster-local storage or avoid wasting backup space on a snapshotted storage. You might want to consult the documentation provided by your HPC.


Examples:

Type: enum (of integer) Default: 1

Specify whether TSV files like coverage and base counts should be 1-based (i.e.: the first base pair position is called 1) like standard practice used in biology and most text formats such as VCF and GFF, or should be 0-based (i.e.: the first base pair position is called 0) like in several Python tools such as pysam and the BED format.

Type: object Default: {}

Properties in this section of the configuration control the input of the pipeline.

The input file for the workflow will be searched in this directory.

V-pipe expects the input samples to be organized in a two-level directory hierarchy.

  • The first level can be, e.g., patient samples or biological replicates of an experiment.
  • The second level can be, e.g., different sampling dates or different sequencing runs of the same sample.
  • Inside that directory, the sub-directory raw_data holds the sequencing data in FASTQ format (optionally compressed with GZip).

Type: object Default: {}

Properties in this section of the configuration control the input of the pipeline.

Type: string Default: "samples/"

The input file for the workflow will be searched in this directory.

V-pipe expects the input samples to be organized in a two-level directory hierarchy.

  • The first level can be, e.g., patient samples or biological replicates of an experiment.
  • The second level can be, e.g., different sampling dates or different sequencing runs of the same sample.
  • Inside that directory, the sub-directory raw_data holds the sequencing data in FASTQ format (optionally compressed with GZip).

Here, we have two samples from patient 1 and one sample from patient 2. By default, V-pipe searches for a file named samples.tsv, if this file does not exist, a list of samples is built by globbing datadir directory contents.

Optionally, the samples file can contain a third column specifying the read length. This is particularly useful when samples are sequenced using protocols with different read lengths.

Optionally, a fourth column can contain a short name of a protocol (e.g.: v3) that is detailed in the file specified in input => protocols_file. This is useful if protocol details such as primers change over time, e.g. to adapt to new variants with SNV breaking primer binding affinity.

Standardized Snakemake workflows place their tables inside the config/ subdirectory, but using this options you can specify alternate locations, e.g., the current working directory (as done in legacy V-pipe v1.x/2.x).

V-pipe can produce several outputs to assess the quality of the output of its steps, e.g., checking whether a sample’s consensus sequence generated by bctfools does result in frameshifting indels and writing a report in sample’s …/references/frameshift_deletions_check.tsv. Such reports can be useful when submitting sequences to GISAID.

By default, we use options -ns_max_n 4 -min_qual_mean 30 -trim_qual_left 30 -trim_qual_right 30 -trim_qual_window 10, which indicates to trim reads using a sliding window with size 10 bp, and trim bases if their quality scores are less than 30. Additionally, reads are filtered out if the average quality score is below 30 and if they contain more than 4 N’s. The user can choose to overwrite the default settings or use additional parameters by using the property extra. E.g., if many reads are filtered out in this step, the user can choose to lower the quality threshold as indicated in the example.
Please do not modify PRINSEQ options -out_format, -out_good, nor -min_len. Instead of using -min_len to define threshold on the read length after trimming, use input => trim_percent_cutoff.

This section is used to set up a timeline of the samples. Some output, e.g., deconvolution of quasispecies mixture using LolliPop, need to have a time component. By default it calls a script that uses regular expressions and look-up tables to extract this information from the samples’ own names. But by using the properties script and options and adapting the environment provided in property conda, it is possible to heavily customize the actions (e.g. it is possible to query an external database instead). For inspiration, see the default script file_parser.py.

If you prefer instead, e.g., such cohort-wide results behind written in a subdirectory of the working directory at the same level as the datadirs, you can use this options you can specify alternate subdirectory relative to the datadir property. (Use .. prefix if you want instead your cohort-wide results to be in a directory at the sample level as samples/ and results/. See the example below to recreate the variants/ directory used by legacy V-pipe v1.x/2.x).


Example:

../variants
+

Type: boolean Default: false

V-pipe can produce several outputs to assess the quality of the output of its steps, e.g., checking whether a sample’s consensus sequence generated by bctfools does result in frameshifting indels and writing a report in sample’s …/references/frameshift_deletions_check.tsv. Such reports can be useful when submitting sequences to GISAID.

This option turns on such QA features.


Example:

True
+

Type: boolean Default: false

This option indicates that the samples come from PCR amplification and the primers should be trimmed from amplicons in the alignment file. The trimmed read are written to each sample’s …/variants/SNVs/REF_aln_trim.bam.

Using this option requires either specifying a primers bed file in input => protocols_file, or using a 4 column input samples TSV file and specify a protocol look-up YAML file in input => protocols_file.


Example:

True
+

Type: boolean Default: false

This option selects whether the SNV caller step should be executed and its output written to each sample’s …/variants/SNVs/snvs.csv.


Example:

True
+

Type: boolean Default: false

This option activates local haplotype reconstruction (only available when using ShoRAH or VILOCA).


Example:

True

Type: boolean Default: false

This option turns on global haplotype reconstruction.


Example:

True
+

Type: boolean Default: false

This option selects whether to generate HTML visualization of the SNVs in each sample’s …/visualization/index.html.


Example:

True
+

Type: boolean Default: false

This option turns on the computation of diversity measures in each sample.


Example:

True
+

Type: boolean Default: false

This option turns on dehumanization of the raw reads (i.e. removal of host’s reads) and generates the file dehuman.cram. This is useful to prepare raw reads for upload on public databases such as, e.g. ENA (European Nucleotide Archive).

This only applies to the upload and does not affect the main workflow.


Example:

Type: boolean Default: false

This option can be used for assistance in incremental upload of data. See section upload for an example.

The path to the different software packages can be specified using this section.

It is especially useful when dependencies are not obtained via conda such as VICUNA, and when the software packages are not in the PATH.

Note we strongly recommend to use conda environments, by adding the --use-conda flag to the V-pipe execution command, e.g. ./vpipe --use-conda. If you prefer to use your own installations, this section allows you to specify the location of the executable files.

We use software PRINSEQ 1 for quality control. By default, we use options -ns_max_n 4 -min_qual_mean 30 -trim_qual_left 30 -trim_qual_right 30 -trim_qual_window 10, which indicates to trim reads using a sliding window with size 10 bp, and trim bases if their quality scores are less than 30. Additionally, reads are filtered out if the average quality score is below 30 and if they contain more than 4 N’s. The user can choose to overwrite the default settings or use additional parameters by using the property extra. E.g., if many reads are filtered out in this step, the user can choose to lower the quality threshold as indicated in the example.
Please do not modify PRINSEQ options -out_format, -out_good, nor -min_len. Instead of using -min_len to define threshold on the read length after trimming, use input => trim_percent_cutoff.

This section is used to set up a timeline of the samples. Some output, e.g., deconvolution of quasispecies mixture using LolliPop, need to have a time component. By default it calls a script that uses regular expressions and look-up tables to extract this information from the samples’ own names. But by using the properties script and options and adapting the environment provided in property conda, it is possible to heavily customize the actions (e.g. it is possible to query an external database instead). For inspiration, see the default script file_parser.py.

Don’t dispatch the timeline rule to the cluster for execution, run locally.


Example:

False
 

Type: string Default: "{VPIPE_BASEDIR}/scripts/file_parser.py"

Script that sets up a timeline of the samples.

Its purpose is to take the V-pipe’s samples TSV file and add two columns:

  • location: location of the sampes
  • date: sampling date of the samples

It will receive the following parameters (in addition to what is specified in property options:

  • –output <OUTPUT>: the output TSV file that must be created by the script.
  • <SAMPLE_TSV>: the input samples TSV file

For an example, see the default script file_parser.py, it uses regular expressions (regex) to parse the first two columns (sample and batch names) and extract a date, and a location code that is further look-ed up in a table. It takes two additional parameters:

  • –locations <LOOKUP>: look-up TSV table mapping the code to full location names
  • –regex_yaml <YAML>: YAML file with regular expressions defining how the date and code are extracted.

Type: string Default: " --no-fallback"

Additional options to be passed to the script, e.g. for an extra configuration file with database server information.

By default, passes an option to the default script to force always using the regex (do not fall back to copy-pasting columns).

Type: string Default: ""

Option for the default script: TSV table that maps location codes (e.g. short alphanumeric codes) used in sample names to full names of locations (e.g. city names).

For example:

 16  Genève (GE)
 Ba  Basel (BS)

-datefmt: "%Y%m%d"
-
  • by default, samples.tsv’s first column (sample names) is used as-is for location codes and the second column (sequencing batch dates) is used for timeline’s date point.
  • YAML’s optional entry sample defines a regular expression to be applied on the first column (sample names)
  • YAML’s optional entry batch defines a regular expression to be applied on the second column (sequencing batch dates)
  • regular expression must define the following named capturing groups:
    • location used for the location codes
    • year, month, day used for the dates of the timeline
    • alternatively, if the date doesn’t use a format with year + month + day elements – e.g., date uses week number of the year – group date can be used to capture the whole date string

But this output is considered temporary and will get deleted by Snakemake once the processing of a sample has finished. To generate dehuman.cram V-pipe would need to run the aligner again, which will both regenerate the data necessary for this output but also generate a new alignment which will trigger the whole workflow again.
