nabu.pipeline.fullfield.processconfig module

class nabu.pipeline.fullfield.processconfig.ProcessConfig(conf_fname=None, conf_dict=None, dataset_info=None, create_logger=False)[source]

Bases: ProcessConfigBase

A ProcessConfig object has these main fields:
  • dataset_info: information about the current dataset

  • nabu_config: configuration from the user side

  • processing_steps/processing_options: configuration “ready-to use” for underlying classes

It is built from the following steps.

(1a) parse config: (conf_fname or conf_dict) –> “nabu_config”

(1b) browse dataset: (nabu_config or existing dataset_info) –> dataset_info

  1. update_dataset_info_with_user_config

  • Update flats/darks

  • CoR (value or estimation method) # no estimation yet

  • rotation angles

  • translations files

  • user sino normalization (eg. subtraction etc)

  1. estimations

  • tilt

  • CoR

  1. coupled validation

  2. build processing steps

  3. configure checkpoints (save/resume)

Initialize a ProcessConfig class.

Parameters:
  • conf_fname (str) – Path to the nabu configuration file. If provided, the parameters conf_dict is ignored.

  • conf_dict (dict) – A dictionary describing the nabu processing steps. If provided, the parameter conf_fname is ignored.

  • dataset_info (DatasetAnalyzer) – A DatasetAnalyzer class instance.

  • checks (bool, optional, default is True) – Whether to perform checks on configuration and datasets (recommended !)

  • remove_unused_radios (bool, optional, default is True) – Whether to remove unused radios, i.e radios present in the dataset, but not explicitly listed in the scan metadata.

  • create_logger (str or bool, optional) – Whether to create a Logger object. Default is False, meaning that the logger object creation is left to the user. If set to True, a Logger object is created, and logs will be written to the file “nabu_dataset_name.log”. If set to a string, a Logger object is created, and the logs will be written to the file specified by this string.
