Define where the pipeline should find input data and save output data.

Path to comma-separated file containing information about the samples in the experiment.

required
type: string
pattern: ^\S+\.csv$

You will need to create a design file with information about the samples in your experiment before running the pipeline. Use this parameter to specify its location. It has to be a comma-separated file with 3 columns, and a header row. See usage docs.

Path or URL to a FASTA genome file for the target genome.

required
type: string
pattern: ^\S+\.fn?a(sta)?(\.gz)?$

Target genome name.

type: string
default: target

By default the target genome is named target and this name is concatenated with the sample IDs using ___ as a separator to construct alignment file names. Use this option to provide a more informative name for the target genome.

The output directory where the results will be saved. You have to use absolute paths to storage on Cloud infrastructure.

required
type: string

Email address for completion summary.

type: string
pattern: ^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$

Set this parameter to your e-mail address to get a summary e-mail with details of the run sent to you when the workflow exits. If set in your user config file (~/.nextflow/config) then you don't need to specify this on the command line for every run.

MultiQC report title. Printed as page header, used for filename if not otherwise specified.

type: string

Select the the LAST seed to index the target genome.

type: string

LAST creates a database of seed sequences in the target genome, and provides different ways to generate these seeds. The default (YASS) searches for long-and-weak similarities that allow for mismatches but not gaps. Among alternatives, there are NEAR for short-and-strong (near-identical) similarities with many gaps (insertions and deletions), MAM8 to find weak similarities with high sensitivity, but low speed and high memory usage, or RY128 that reduces run time and memory use, by only seeking seeds at ~1/128 of positions in each sequence, which is useful when the purpose of running this pipeline is only to generate whole-genome dotplots, or when sensitivity for tiny fragments may be unnecessary or undesirable. See https://gitlab.com/mcfrith/last/-/blob/main/doc/last-seeds.rst for details.

Customise the way to mask the target genome.

type: string

In this pipeline, letters soft-masked in lowercase are excluded from indexing (lastdb -c). By default, the original mask is removed and a new one is made with an internal verison of the “tantan” tool. Set this option to original to keep the orininal soft-masking. See https://gitlab.com/mcfrith/last/-/blob/main/doc/lastdb.rst for details.

Arguments for the lastdb, last-train, lastal and last-split programs.

Make a many to many alignment

type: boolean

This adds time and can comsume considerable amount of space; use only if you need that data, for instance in the case of a self-alignment

Path to a file containing alignment parameters or a scoring matrix. If this option is used, last-train will be skipped and alignment parameters will be the same for each query.

type: string

Arguments passed to both last-train and lastal.

type: string
default: -C2 -D1e9

Arguments passed only to lastal (useful when they are not recognised by last-train).

type: string

Mismap probability cutoff for last-split.

type: string
default: 0.00001

Customise dot-plots or skip them.

Extra arguments passed to last-dotplot to customise the output. See https://gitlab.com/mcfrith/last/-/blob/main/doc/last-dotplot.rst.

type: string

Do not generate the one-to-many alignment dot-plot.

type: boolean

Do not generate the one-to-one alignment dot-plot.

type: boolean

Do not generate the many-to-one alignment dot-plot.

type: boolean

Do not generate the many-to-many alignment dot-plot.

type: boolean

Reference genome related files and options required for the workflow.

Name of iGenomes reference.

type: string

If using a reference genome configured in the pipeline using iGenomes, use this parameter to give the ID for the reference. This is then used to build the full paths for all required reference genome files e.g. --genome GRCh38.

See the nf-core website docs for more details.

Path to FASTA genome file.

type: string
pattern: ^\S+\.fn?a(sta)?(\.gz)?$

This parameter is mandatory if --genome is not specified. If you don't have a BWA index available this will be generated for you automatically. Combine with --save_reference to save BWA index for future runs.

Do not load the iGenomes reference config.

hidden
type: boolean

Do not load igenomes.config when running the pipeline. You may choose this option if you observe clashes between custom parameters and those supplied in igenomes.config.

Parameters used to describe centralised config profiles. These should not be edited.

Git commit id for Institutional configs.

hidden
type: string
default: master

Base directory for Institutional configs.

hidden
type: string
default: https://raw.githubusercontent.com/nf-core/configs/master

If you're running offline, Nextflow will not be able to fetch the institutional config files from the internet. If you don't need them, then this is not a problem. If you do need them, you should download the files from the repo and tell Nextflow where to find them with this parameter.

Maximum amount of memory that can be requested for any single job.

hidden
type: string
default: 128.GB

Method used to save pipeline results to output directory.

hidden

hidden
type: boolean
default: true

Validation of parameters fails when an unrecognised parameter is found.

hidden
