# Sasdata

A package for loading and handling reduced small angle scattering data.

The data loaders provided are usable as a standalone package, or in conjunction with the sasview analysis package.

## Install
The easiest way to use sasdata is by using [SasView](http://www.sasview.org).

You can also install sasdata as a standalone package in python. To create a python environment with the sasdata dependencies
 - Using a python virtual environment::

    $ python -m venv sasdata
    $ python -m pip install numpy lxml h5py xmlrunner "pytest<6"
   - Activate the environment::
       $ .\sasdata\Scripts\activate
 
 - Using [miniconda](https://docs.conda.io/en/latest/miniconda.html)
or [anaconda](https://www.anaconda.com/)::

    $ conda create -n sasdata -c conda-forge numpy lxml h5py xmlrunner "pytest<6"
 
   - Activate the environment and install sasdata::

        $ conda activate sasdata
        $ (sasdata) $ pip install sasdata

## Usage

Loading data sets:

    (sasdata) $ python
    >>> from sasdata.dataloader.loader import Loader
    >>> loader_module = Loader()
    >>> loaded_data_sets = loader_module.load(path="/path/to/file.ext")

 - The Loader() class is not callable and must be instantiated prior to use.
 - The load() method returns a list of Data1/2D objects as loaded from the specified path.

Saving loaded data:

    >>> loaded_data_set = loaded_data_sets[0]
    >>> loader.save(path='/path/to/new/file.ext', data=loaded_data_set, format=None)

 - The save() method accepts three (3) arguments:
   - path: The file name and path to save the data.
   - data: A Data1D or Data2D object.
   - format (optional): The expected file extension for the file. Options include:
     - .xml: for the canSAS XMl format
     - .h5: for the NXcanSAS format
     - .txt: for the multi-column ascii format
     - .csv: for a comma delimited text format.
 - The file extension specified in the save path will be superseded by the format value.
