Summary


NxtomoLoader
Process categoryBrief description

Computational demand

for typical tomography data

(low, medium, high)

Comment(s)Reference(s)Common alternative process(es)
loaderTo load raw data from input file(s).Uses lazy loading (see Comment 1).
  1. When data are eventually required for processing by the next process in a given process list, then they are actually loaded, with loading times depending on data chunking of the input dataset(s).
  2. Capable of handling the case of dark- and flat-field images being supplied in datasets stored in individual NeXus datasets.

    1)                preview : []
    A slice list of required frames.
    2)         image_key_path : entry1/tomo_entry/instrument/detector/image_key
    Path to the image key entry inside the nxs file.
    3)                   name : tomo
    The name assigned to the dataset.
    4)               3d_to_4d : False
    Set to true if this reshape is required.

    Optional Path to the flat field data file, nxs path and scale value.
    6)              data_path : entry1/tomo_entry/data/data
    Path to the data inside the file.
    7)                   dark : [None, None, 1]
    Optional path to the dark field data file, nxs path and scale value.
    8)                 angles : None
    A python statement to be evaluated or a file.
    9)           ignore_flats : None
    List of batch numbers of flats (start at 1) to ignore.
