Convert PLINK files to genotype matrix.

Requires PLINK v2. The .raw/.traw file is generated by plink and then transformed to a genotype matrix file. See https://www.cog-genomics.org/plink/2.0/formats#raw and https://www.cog-genomics.org/plink/2.0/formats#traw for more information.

        .gcountx for the added columns.

Register a virtual subclass of an ABC.

Returns the subclass, to allow usage as a class decorator.

staticmethod
__instancecheck__(cls, instance)

Override for isinstance(instance, cls).

staticmethod
__subclasscheck__(cls, subclass)

Override for issubclass(subclass, cls).

staticmethod
__repr__(cls) → str

Representation for the Proc subclasses

staticmethod
__call__(cls, *args, **kwds)

Make sure Proc subclasses are singletons

Parameters
  • *args (Any) and
  • **kwds (Any) Arguments for the constructor
Returns (Proc)

The Proc instance

classmethod

from_proc(proc, name=None, desc=None, envs=None, envs_depth=None, cache=None, export=None, error_strategy=None, num_retries=None, forks=None, input_data=None, order=None, plugin_opts=None, requires=None, scheduler=None, scheduler_opts=None, submission_batch=None)

Create a subclass of Proc using another Proc subclass or Proc itself

Parameters
  • proc (Type) The Proc subclass
  • name (str, optional) The new name of the process
  • desc (str, optional) The new description of the process
  • envs (Mapping, optional) The arguments of the process, will overwrite parent oneThe items that are specified will be inherited
  • envs_depth (int, optional) How deep to update the envs when subclassed.
  • cache (bool, optional) Whether we should check the cache for the jobs
  • export (bool, optional) 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
  • error_strategy (str, optional) 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
  • num_retries (int, optional) How many times to retry to jobs once error occurs
  • forks (int, optional) New forks for the new process
  • input_data (Any, optional) The input data for the process. Only when this processis a start process
  • order (int, optional) The order to execute the new process
  • plugin_opts (Mapping, optional) The new plugin options, unspecified items will beinherited.
  • requires (Sequence, optional) The required processes for the new process
  • scheduler (str, optional) The new shedular to run the new process
  • scheduler_opts (Mapping, optional) The new scheduler options, unspecified items willbe inherited.
  • submission_batch (int, optional) How many jobs to be submited simultaneously
Returns (Type)

The new process class

classmethod

__init_subclass__()

Parameters
