mr_utils.load_data.raw.load_raw(filename, use='bart', bart_args='-A', s2i_ROS=True, as_ismrmrd=False)[source]

Load Siemens raw data into numpy array.

Parameters:
  • filename (str) – File path and filename of raw data file.
  • use ({'bart', 's2i', 'rdi'}, optional) – Method to use to read in raw data.
  • bart_args (dict, optional) – Arguments to pass to BART.
  • s2i_ROS (bool, optional) – Remove oversampling in readout when using use=’s2i’.
  • as_ismrmrd (bool, optional) – Leave as ismrmrd data type.
Returns:

  • data (array_like) – Data from raw data file.
  • ismrmrd_dataset (optional) – Returned if use=’s2i’ and as_ismrmrd=True.
Raises:
  • SystemError – If BART is requested but not installed or if siemens_to_ismrmrd is requested but not installed
  • Exception – If BART encounters an error while running or if siemens_to_ismrmrd is encounters an error while running, or a valid use option is not specified.

Notes

use: - bart – BART twix raw data reader - s2i – siemens_to_ismrmrd - rdi – rawdatarinator
