Project description
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.

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
-
$ 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- The file extension specified in the save path will be superseded by the format value.
