# obspy.clients.filesystem.sds.Client.__init__

`Client.``__init__`(sds_root, sds_type='D', format='MSEED', fileborder_seconds=30, fileborder_samples=5000)

  Initialize a SDS local filesystem client.

      >>> from obspy.clients.filesystem.sds import Client
      >>> client = Client("/my/SDS/archive/root")

  Parameters: | sds_root (str) Root directory of SDS archive. sds_type (str) SDS data type identifier, one single character. Types recommended by the SDS definition are: ‘D’ - Waveform data, ‘E’ - Detection data, ‘L’ - Log data, ‘T’ - Timing data, ‘C’ - Calibration data, ‘R’ - Response data, ‘O’ - Opaque data. Can also be wildcarded by setting to `?` or `*`. format (str) File format the data is stored in, see `read()` for a list of file formats supported by ObsPy. Usually, SDS archives are stored in “MSEED” format. Can be set to `None` for file format autodetection (slowing down the reading). fileborder_seconds (float) Defines in which cases the client checks the previous/next daily file for the requested data (data in SDS archives usually spill over on the day break, at least for a few seconds). For example setting `fileborder_seconds=30` means that for a request with `starttime` at `00:00:29` UTC (or an `endtime` at `23:59:31`), the previous daily file is also checked, if it contains matching data. The maximum of both `fileborder_seconds` and `fileborder_samples` is used when determining if previous/next day should be checked for data. fileborder_samples (int) Similar to `fileborder_seconds`. The given number of samples is converted to seconds by mapping the band code of the requested channel to sampling frequency. The maximum of both `fileborder_seconds` and `fileborder_samples` is used when determining if previous/next day should be checked for data.
