- 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")
- 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.
