runmanager.next_sequence_index

runmanager.next_sequence_index(shot_basedir, dt, increment=True)

Return the next sequence index for sequences in the given base directory (i.e. <experiment_shot_storage>/<script_basename>) and the date of the given datetime object, and increment the sequence index atomically on disk if increment=True. If not setting increment=True, then the result is indicative only and may be used by other code at any time. One must increment the sequence index prior to use.
