sas.dataloader.readers package

Submodules

sas.dataloader.readers.IgorReader module

IGOR 2D reduced file reader

class sas.dataloader.readers.IgorReader.Reader

Simple data reader for Igor data files

ext = ['.ASC', '.asc']

read(filename=None)

Read file

type = ['IGOR 2D files (*.ASC)|*.ASC']

type_name = 'IGOR 2D'

sas.dataloader.readers.abs_reader module

class sas.dataloader.readers.abs_reader.Reader

Class to load IGOR reduced .ABS files

ext = ['.abs', '.ABS']

read(path)

Load data file.

Parameters:

path – file path

Returns:

Data1D object, or None

Raises:

• RuntimeError – when the file can’t be opened
• ValueError – when the length of the data vectors are inconsistent

type = ['IGOR 1D files (*.abs)|*.abs']

type_name = 'IGOR 1D'

sas.dataloader.readers.ascii_reader module

ASCII reader

class sas.dataloader.readers.ascii_reader.Reader

Class to load ascii files (2, 3 or 4 columns).

allow_all = True

ext = ['.txt', '.TXT', '.dat', '.DAT', '.abs', '.ABS', 'csv', 'CSV']

read(path)

Load data file

Parameters:

path – file path

Returns:

Data1D object, or None

Raises:

• RuntimeError – when the file can’t be opened
• ValueError – when the length of the data vectors are inconsistent

type = ['ASCII files (*.txt)|*.txt', 'ASCII files (*.dat)|*.dat', 'ASCII files (*.abs)|*.abs', 'CSV files (*.csv)|*.csv']

type_name = 'ASCII'

sas.dataloader.readers.associations module

Module to associate default readers to file extensions. The module reads an xml file to get the readers for each file extension. The readers are tried in order they appear when reading a file.

sas.dataloader.readers.associations.read_associations(loader, settings='defaults.xml')

Read the specified settings file to associate default readers to file extension.

Parameters:

• loader – Loader object
• settings – path to the XML settings file [string]

sas.dataloader.readers.associations.register_readers(registry_function)

Function called by the registry/loader object to register all default readers using a call back function.

WARNING:this method is now obsolete Parameters:registry_function – function to be called to register each reader

sas.dataloader.readers.cansas_constants module

Information relating to the CanSAS data format. These constants are used in the cansas_reader.py file to read in any version of the cansas format.

class sas.dataloader.readers.cansas_constants.CansasConstants

The base class to define where all of the data is to be saved by cansas_reader.py.
