# obspy.io.mseed.core._write_mseed¶

_write_mseed(stream, filename, encoding=None, reclen=None, byteorder=None, sequence_number=None, flush=True, verbose=0, **_kwargs)[source]

Write Mini-SEED file from a Stream object.

Warning

This function should NOT be called directly, it registers via the the write() method of an ObsPy Stream object, call this instead.

Parameters: stream (Stream) A Stream object. filename (str) Name of the output file or a file-like object. encoding (int or str, optional) Should be set to one of the following supported Mini-SEED data encoding formats: ASCII (0)*, INT16 (1), INT32 (3), FLOAT32 (4)*, FLOAT64 (5)*, STEIM1 (10) and STEIM2 (11)*. If no encoding is given it will be derived from the dtype of the data and the appropriate default encoding (depicted with an asterix) will be chosen. reclen (int, optional) Should be set to the desired data record length in bytes which must be expressible as 2 raised to the power of X where X is between (and including) 8 to 20. Defaults to 4096 byteorder (int or str, optional) Must be either 0 or '<' for LSBF or little-endian, 1 or '>' for MBF or big-endian. '=' is the native byte order. If -1 it will be passed directly to libmseed which will also default it to big endian. Defaults to big endian. sequence_number (int, optional) Must be an integer ranging between 1 and 999999. Represents the sequence count of the first record of each Trace. Defaults to 1. flush (bool, optional) If True, all data will be packed into records. If False new records will only be created when there is enough data to completely fill a record. Be careful with this. If in doubt, choose True which is also the default value. verbose (int, optional) Controls verbosity, a value of 0 will result in no diagnostic output.

Note

The reclen, encoding, byteorder and sequence_count keyword arguments can be set in the stats.mseed of each Trace as well as kwargs of this function. If both are given the kwargs will be used.

The stats.mseed.blkt1001.timing_quality value will also be written if it is set.

The stats.mseed.blkt1001.timing_quality value will also be written if it is set.
