• Adds 'nprocs' option to previewing
• Fixes 'File write failed' error caused by ROMIO 2GB read/write limit and h5py create_dataset
  • Replaces h5py create_dataset (with chunking) with direct hdf5 calls, to avoid initialisation of the created file.

Plugin Updates:

• Adds iterative plugin driver

  • Improves astra toolbox wrappers
  • Improves base recon and centre/outer padding
    • Padding is now only allowed for suitable methods (e.g. yes for FBP but no for iterative methods)

Version 2.0

  • processed each call to process_frames()
    • Requires big changes to data slicing
  • Auto-mates and optimises number of transfer_frames and process_frames
  • Fixes the number of frames sent to the plugin
• Closes and re-opens hdf5 files after each plugin to allow immediate access.

  • can now be applied to single entry darks and/or flats
• Updates Reconstructions:
  • option to apply mask to data
  • Adds option of cropping sinogram if centre needs shifting
• Updates DistortionCorrection:
  • Updates to parameters to allow easier parameter tuning of centre values
  • Automates shifting centre of distortion when data is previewed
• Updates DownsampleFilter:
  • Updates to work with > 3D data
  • Simplifies with scikit image
• Updates VoCentering: Uses different smooth filters for coarse and fine search to avoid local minima
• Updates MedianFilter: generalised for different data dimensionality
• Fixes MultiNxtomoLoader
• Re-organised plugins into collections
• All plugins now call process_frames() function
