Parameters

Input/output options

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

--input

type: 'string'

Path to YAML file containing information about the dataset

required

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.

pattern: ^\S+\.yaml$

--outdir

type: 'string'

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

required

--email

type: 'string'

Email address for completion summary.

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.

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

Kmer profiling options

Options for the kmer profiling subworkflow.

--kmer_size

type: 'integer'

Kmer size to use for all kmer-based subroutines in the Kmer profiling subworkflow. This parameter is overridden by the provided kmer size for a given input read set if a FastK database is provided.

default: 31

Raw assembly options

Options for tuning the outputs of raw assembies.

--enable_hic_phasing

type: 'boolean'

If Hi-C data is provided, enabling this will produce a Hi-C phased assembly with hifiasm.

--enable_trio_binning

type: 'boolean'

If parental read data is provided, enabling this will produce a trio binned assembly with hifiasm.

--hifiasm_error_correction_options

type: 'string'

Options controlling Hifiasm error correction.

See the "Error correction options" section of https://hifiasm.readthedocs.io/en/latest/parameter-reference.html for options.

--hifiasm_assembly_options

type: 'string'

Options controlling Hifiasm assembly output, including those affecting assemblty, purging, phasing and trio binning.

Purging options

--purging_assemblytypes

type: 'string'

A comma-separated list defining which types of assemblies to purge. Must draw from the options "primary", "hic_phased", or "trio_binned".

default: 'primary'

--purging_purge_middle

type: 'boolean'

During haplotype purging, look in the middle of contigs for potential haplotigs. This removes the "-e" option from the purgedups/getseqs command.

--purging_cutoffs

type: 'string'

Manually override the cutoffs set by purge_dups/calcuts. Must be a comma-separated string with three coverage cutoffs - low, medium, and high - for example. "5,20,100".

Polishing options

Options for polishing genomes with 10X Illumina reads.

--enable_polishing

type: 'boolean'

Switch on to do polish purged assembly before scaffolding

--bed_chunks_polishing

type: 'integer'

Number of chunks to split assembly into for polishing.

default: 100

Scaffolding options

--cool_bin

type: 'integer'

Number of bins for cooler cload

default: 1000

Organelle assembly

--enable_organelles

type: 'boolean'

Enable organellar assembly subroutines.

default: 1

Institutional config options

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

hidden

The centralised nf-core configuration profiles use a handful of pipeline parameters to describe themselves. This information is then printed to the Nextflow log when you run a pipeline. You should not need to change these values when you run a pipeline.

--custom_config_version

type: 'string'

Git commit id for Institutional configs.

default: 'master'
hidden

--custom_config_base

type: 'string'

Base directory for Institutional configs.

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

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.

--config_profile_name

type: 'string'

Institutional config name.

hidden

--config_profile_description

type: 'string'

Institutional config description.

hidden

--config_profile_contact

type: 'string'

Institutional config contact information.

hidden

--config_profile_url

type: 'string'

Institutional config URL link.

hidden

Generic options

Less common options for the pipeline, typically set in a config file.

hidden

These options are common to all nf-core pipelines and allow you to customise some of the core preferences for how the pipeline runs.

Typically these options would be set in a Nextflow config file loaded for all pipeline runs, such as ~/.nextflow/config.

--version

type: 'boolean'

Display version and exit.

hidden

--publish_dir_mode

type: 'string'

Method used to save pipeline results to output directory.

The Nextflow publishDir option specifies which intermediate files should be saved to the output directory. This option tells the pipeline what method should be used to move these files. See Nextflow docs for details.

--email_on_fail

type: 'string'

Email address for completion summary, only when pipeline fails.

hidden

An email address to send a summary email to when the pipeline is completed - ONLY sent if the pipeline does not exit successfully.

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

--plaintext_email

type: 'boolean'

Send plain-text email instead of HTML.

hidden

--monochrome_logs

type: 'boolean'

Do not use coloured log outputs.

hidden

--hook_url

type: 'string'

Incoming hook URL for messaging service

hidden

Incoming hook URL for messaging service. Currently, MS Teams and Slack are supported.

--validate_params

type: 'boolean'

Boolean whether to validate parameters against the schema at runtime

default: 1
hidden

--pipelines_testdata_base_path

type: 'string'

Base URL or local path to location of pipeline test dataset files

default: 'https://raw.githubusercontent.com/nf-core/test-datasets/'
hidden

--trace_report_suffix

type: 'string'

Suffix to add to the trace report filename. Default is the date and time in the format yyyy-MM-dd_HH-mm-ss.

hidden

The following uncommon parameters have been hidden: --custom_config_version, --custom_config_base, --config_profile_name, --config_profile_description, --config_profile_contact, --config_profile_url, --version, --publish_dir_mode, --email_on_fail, --plaintext_email, --monochrome_logs, --hook_url, --validate_params, --pipelines_testdata_base_path, --trace_report_suffix
