A collection of custom-tailored scripts and applied utilities built with Viash.
A collection of custom-tailored scripts and applied utilities built with
Viash.
craftbox is a curated collection of custom scripts and utilities
designed to tackle context-specific tasks.
Emphasizing the Viash principles, craftbox components aim for
reusability, reproducibility, and adherence to best
practices. Key features generally include:
Standalone & Nextflow Ready: Components are built to run directly
via the command line or be smoothly integrated into Nextflow
workflows.
Custom Implementations: Contains scripts and tools developed for
particular tasks that may not be found in broader collections.
High Quality Standards (promoted by Viash):
Clear documentation for components and their parameters.
Full exposure of underlying script/tool arguments for fine-grained
control.
Containerized (Docker) to ensure dependency management and a
consistent, reproducible runtime environment.
Unit tested where applicable to ensure components function as
expected.
Viash components in craftbox can be run in various ways:
You can run this component directly from the Viash Hub Launch
interface.

You can run this component directly from the command line using the
Viash CLI.
viash run vsh://craftbox@v0.3.3/concat_rtext -- --help
viash run vsh://craftbox@v0.3.3/concat_rtext -- \
--input path/to/input.txt \
--input path/to/compressed.txt.gz \
--output path/to/output.txt This will run the component with the specified input files and output
the results to the specified output file.
You can run this component as a Nextflow pipeline.
nextflow run https://packages.viash-hub.com/vsh/craftbox \
-revision v0.3.3 \
-main-script target/nextflow/concat_rtext/main.nf \
-latest -resume \
-profile docker \
--input "path/to/input.txt;path/to/compressed.txt.gz" \
--output path/to/output.txt Note: Make sure that the Nextflow
SCM is
set up properly. You can do this by adding the following lines to your~/.nextflow/scm file:
providers.vsh.platform = 'gitlab'
providers.vsh.server = 'https://packages.viash-hub.com' Tip: This will also work with Seqera Cloud or other
Nextflow-compatible platforms.
In your Viash config file (config.vsh.yaml), you can add this
component as a dependency:
dependencies:
- name: concat_rtext
repository: vsh://craftbox@v0.3.3 Tip: See the Viash
documentation
for more details on how to use Viash components as a dependency in your
own Nextflow workflows.
