Run pipseeker full command

Tested with pipseeker v3.3.0

Attributes
  • cache — Should we detect whether the jobs are cached?
  • desc — The description of the process. Will use the summary fromthe docstring by default.
  • dirsig — When checking the signature for caching, whether should we walkthrough the content of the directory? This is sometimes time-consuming if the directory is big.
  • envs — The arguments that are job-independent, useful for common optionsacross jobs.
  • envs_depth — How deep to update the envs when subclassed.
  • error_strategy — How to deal with the errors
    • - retry, ignore, halt
    • - halt to halt the whole pipeline, no submitting new jobs
    • - terminate to just terminate the job itself
  • export — When True, the results will be exported to <pipeline.outdir>Defaults to None, meaning only end processes will export. You can set it to True/False to enable or disable exporting for processes
  • forks — How many jobs to run simultaneously?
  • input — The keys for the input channel
  • input_data — The input data (will be computed for dependent processes)
  • lang — The language for the script to run. Should be the path to theinterpreter if lang is not in $PATH.
  • name — The name of the process. Will use the class name by default.
  • nexts — Computed from requires to build the process relationships
  • num_retries — How many times to retry to jobs once error occurs
  • order — The execution order for this process. The bigger the numberis, the later the process will be executed. Default: 0. Note that the dependent processes will always be executed first. This doesn't work for start processes either, whose orders are determined by Pipen.set_starts()
  • output — The output keys for the output channel(the data will be computed)
  • output_data — The output data (to pass to the next processes)
  • output_flatten — Whether to flatten the output when saving to the outputdirectory. Normally, the output will be saved in a subdirectory named after the job index (e.g. <outdir>/0, <outdir>/1, etc.). If output_flatten is True, the output will be saved directly in the output directory without the subdirectories. This is useful when you want the job outputs to be directly revealed in the output directory. Note that this only works for processes with export=True or end processes and make sure the name of the output files won't conflict for jobs with each other when flattening. It takes 3 possible values
    • - None (default): flatten the output for single-job processes only
    • - True: flatten the output for all processes
    • - False: never flatten the output
  • plugin_opts — Options for process-level plugins
  • requires — The dependency processes
  • scheduler — The scheduler to run the jobs
  • scheduler_opts — The options for the scheduler
  • script — The script template for the process
  • submission_batch — How many jobs to be submited simultaneously.The program entrance for some schedulers may take too much resources when submitting a job or checking the job status. So we may use a smaller number here to limit the simultaneous submissions.
  • template — Define the template engine to use.This could be either a template engine or a dict with key engine indicating the template engine and the rest the arguments passed to the constructor of the pipen.template.Template object. The template engine could be either the name of the engine, currently jinja2 and liquidpy are supported, or a subclass of pipen.template.Template. You can subclass pipen.template.Template to use your own template engine.
Input
  • fastqs — The input fastq file
Output
  • outdir — The output directory
Envs
  • — Other arguments passed to pipseeker full command.See https://www.fluentbio.com/wp-content/uploads/2024/06/PIPseeker-v3.3-User-Guide.pdf for more details.
  • chemistry — Version of the PIPseq assay (v3, v4, or V).
  • ncores — Number of cores to useWill be passed to pipseeker with --threads.
  • pipseeker — Path to pipseeker executable
  • ref — Path of folder containing STAR-compatible transcriptome referenceWill be passed to pipseeker with --star-index-path.
  • remove_bam (flag) — Whether to remove the BAM file generated by pipseeker.
  • skip_version_check (flag) — Whether to skip newer version check of pipseeker.
  • tmpdir — Path to temporary directory, used to save the soft-lined fastq filesto pass to cellranger.
  • verbosity — The verbosity level of pipseeker.
