Description:
 def read(cls, source, *args, **kwargs):
 """Read data into a `StateVector` Parameters source : `str`, `list` Source of data, any of the following: - `str` path of single data file, - `str` path of LAL-format cache file, - `list` of paths. channel : `str`, `~gwpy.detector.Channel` the name of the channel to read, or a `Channel` object. start : `~gwpy.time.LIGOTimeGPS`, `float`, `str` GPS start time of required data, any input parseable by `~gwpy.time.to_gps` is fine end : `~gwpy.time.LIGOTimeGPS`, `float`, `str`, optional GPS end time of required data, defaults to end of data found; any input parseable by `~gwpy.time.to_gps` is fine bits : `list`, optional list of bits names for this `StateVector`, give `None` at any point in the list to mask that bit format : `str`, optional source format identifier. If not given, the format will be detected if possible. See below for list of acceptable formats. nproc : `int`, optional, default: `1` number of parallel processes to use, serial process by default. gap : `str`, optional how to handle gaps in the cache, one of - 'ignore': do nothing, let the undelying reader method handle it - 'warn': do nothing except print a warning to the screen - 'raise': raise an exception upon finding a gap (default) - 'pad': insert a value to fill the gaps pad : `float`, optional value with which to fill gaps in the source data, only used if gap is not given, or `gap='pad'` is given Examples -------- To read the S6 state vector, with names for all the bits:: 'H-H1_LDAS_C02_L2-968654592-128.gwf', 'H1:IFO-SV_STATE_VECTOR', bits=['Science mode', 'Conlog OK', 'Locked', 'No injections', 'No Excitations'], dtype='uint32') then you can convert these to segments or to read just the interferometer operations bits:: 'H-H1_LDAS_C02_L2-968654592-128.gwf', 'H1:IFO-SV_STATE_VECTOR', bits=['Science mode', None, 'Locked'], dtype='uint32') Running `to_dqflags` on this example would only give 2 flags, rather than all five. Alternatively the `bits` attribute can be reset after reading, but before any further operations. Notes -----"""
