Data access Data access

  • Loader service for many file formats:

– HDF5 – CBF – common images PNG, TIFF, etc – proprietary area detector outputs – plugin extendibility for other formats

Datasets Datasets

  • N-dimensional, multiple types
  • Lazy loading capability
  • Slicing for subsets
  • NumPy-like broadcasting in many
  • perations
  • Library of mathematical and statistical
  • perations

Metadata Metadata

  • Can be loaded independently of data
  • Associated with files and also datasets
  • Experimental context and environment
  • Units, errors, scan positions, etc

Future work uture work

  • Commit concrete implementations to

Eclipse project

  • More visualization including volume

rendering of isosurfaces with JavaFX

  • Lazy or deferred evaluation of operations
  • n datasets
  • Error propagation in operations on

datasets
