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 2 or 5 columns, plus a header row. See usage docs.

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.

Please see the 10x website to download either of the supported human or mouse references. If not specified the GRCh38 human reference is automatically downladed and used.

Additional intermediate output files that can be optionally saved.

Save the extracted tar archive of the Space Ranger reference.

type: boolean

By default, extracted versions of archived Space Ranger reference data will not be saved to the results directory. Specify this flag (or set to true in your config file) to copy these files to the results directory when complete.

Save extracted tar archives of input data.

type: boolean

By default, extracted versions of archived input data will not be saved to the results directory. Specify this flag (or set to true in your config file) to copy these files to the results directory when complete.

Options related to the downstream analyses performed by the pipeline.

The minimum number of UMIs needed in a spot for that spot to pass the filtering.

type: integer
default: 500

The minimum number of expressed genes in a spot needed for that spot to pass the filtering.

type: integer
default: 250

The minimum number of spots in which a gene is expressed for that gene to pass the filtering.

type: integer
default: 1

The maximum proportion of mitochondrial content that a spot is allowed to have to pass the filtering.

type: number
default: 20

If you do not wish to filter based on mitochondrial content, set this parameter to 100.

The minimum proportion of ribosomal content that a spot is needs to have to pass the filtering (no filtering is done by default).

type: number

The maximum proportion of haemoglobin content that a spot is allowed to have to pass the filtering (no filtering is done by default).

type: number
default: 100

The number of top highly variable genes to use for the analyses.

type: integer
default: 2000

The resolution for the clustering of the spots.

type: number
default: 1

The resolution controls the coarseness of the clustering, where a higher resolution leads to more clusters.

The method to use for spatially variable gene autocorrelation.

type: string

The number of top spatially variable genes to plot.

type: integer
default: 14

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.

Institutional config name.

hidden
type: string

Institutional config description.

hidden
type: string

Institutional config contact information.

hidden
type: string

Institutional config URL link.

hidden
type: string

Set the top limit for requested resources for any single job.

Maximum number of CPUs that can be requested for any single job.

hidden
type: integer
default: 64

Use to set an upper-limit for the CPU requirement for each process. Should be an integer e.g. --max_cpus 1

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

hidden
type: string
default: 128.GB
pattern: ^\d+(\.\d+)?\.?\s*(K|M|G|T)?B$

Use to set an upper-limit for the memory requirement for each process. Should be a string in the format integer-unit e.g. --max_memory '8.GB'

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

hidden
type: string
default: 240.h
pattern: ^(\d+\.?\s*(s|m|h|d|day)\s*)+$

Use to set an upper-limit for the time requirement for each process. Should be a string in the format integer-unit e.g. --max_time '2.h'

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

Display help text.

hidden
type: boolean

Display version and exit.

hidden
type: boolean

Method used to save pipeline results to output directory.

hidden
type: string

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 address for completion summary, only when pipeline fails.

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

hidden
type: string
default: 25.MB

type: string

Boolean whether to validate parameters against the schema at runtime

hidden
type: boolean
default: true

Show all params when using --help

hidden
type: boolean

By default, parameters set as hidden in the schema are not shown on the command line when a user runs with --help. Specifying this option will tell the pipeline to show all parameters.

Validation of parameters fails when an unrecognised parameter is found.

hidden
type: boolean

By default, when an unrecognised parameter is found, it returns a warinig.

Validation of parameters in lenient more.

hidden
type: boolean

Allows string values that are parseable as numbers or booleans. For further information see JSONSchema docs.
