Method Details [hide private]

__init__(self, qubx)
(Constructor)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)

gen_samples(self, chunks, main_hold=None, signal=None, maxlen=1048576, get_excluded=False)

source code 

Yields a SourceChunk with fields .samples and .sampling for each in chunks.

Parameters:
  • chunks - list of SourceChunk
  • main_hold - qubx.task.GTK_Main_Hold if in a worker thread, or None in the main thread
  • signal - signal index, or None to use the chunk.signal
  • maxlen - chunks longer than this will be yielded in pieces
  • get_excluded - if True, yields sampled chunks even when included==False (if False, yields orig chunk when excluded).

get_idealization(self, chunk, signal=None, mark_excluded=False, get_fragments=False, get_durations=False)

source code 

Returns the dwells in chunk as numpy arrays

Parameters:
  • chunk - SourceChunk
  • signal - signal index, or None to use the chunk.signal
  • mark_excluded - if True, replaces excluded dwells with class -1 (or -2?)
  • get_fragments - if False, omits first/last dwells if incomplete
  • get_durations - if True, returns durations
Returns:
firsts, lasts, classes[, durations]

get_segmentation(self, dataview=None, first_seg=None, last_seg=None, left=None, right=None, signal=None, latency=None, baseline_nodes=True)

source code 

Returns a list of SourceSeg corresponding to source, modified by args.

Parameters:
  • dataview - QubDataView, or None for the file onscreen
  • first_seg
  • last_seg
  • left - time offset from start-of-each-seg
  • right - time offset from start-of-each-seg
  • signal - index of data signal
  • latency - shift the data to the right by this many samples
  • baseline_nodes - True to subtract baseline nodes
