Nextflow Platform

Warning

Deprecated since 0.9.0. Planned removal at 0.10.0. Use ‘engines’ and ‘runners’ instead.

Platform for generating Nextflow VDSL3 modules.

Example:

platforms:
  - type: nextflow
    directives:
      label: [lowcpu, midmem]

auto

Type: NextflowAuto

Default: simplifyInput: true simplifyOutput: false transcript: false publish: false

Automated processing flags which can be toggled on or off:

Flag	Description	Default
`simplifyInput`	If `true`, an input tuple only containing only a single File (e.g. `["foo", file("in.h5ad")]`) is automatically transformed to a map (i.e. `["foo", [ input: file("in.h5ad") ] ]`).	`true`
`simplifyOutput`	If `true`, an output tuple containing a map with a File (e.g. `["foo", [ output: file("out.h5ad") ] ]`) is automatically transformed to a map (i.e. `["foo", file("out.h5ad")]`).	`false`
`transcript`	If `true`, the module’s transcripts from `work/` are automatically published to `params.transcriptDir`. If not defined, `params.publishDir + "/_transcripts"` will be used. Will throw an error if neither are defined.	`false`
`publish`	If `true`, the module’s outputs are automatically published to `params.publishDir`. If equal to `"state"`, also a `.state.yaml` file will be published in the publish dir. Will throw an error if `params.publishDir` is not defined.	`false`

Example:

auto:
  publish: true

Type: NextflowConfig

Default: A series of default labels to specify memory and cpu constraints

Allows tweaking how the Nextflow Config file is generated.

Type: String

Default: docker

Specifies the Docker platform id to be used to run Nextflow.

Type: Boolean

Default: False

Whether or not to print debug messages.

Type: NextflowDirectives

Default: Empty

Directives are optional settings that affect the execution of the process. These mostly match up with the Nextflow counterparts.

Example:

directives:
  container: rocker/r-ver:4.1
  label: highcpu
  cpus: 4
  memory: 16 GB

Type: String

Default: nextflow

Every platform can be given a specific id that can later be referred to explicitly when running or building the Viash component.

Example:

id: foo

Type: String

Specifies the type of the platform.
