"""Write a channel of data in Digital RF format.
In addition to storing the input samples in Digital RF format, this
block also populates the channel's accompanying Digital Metadata
at the sample indices when the metadata changes or a data skip occurs.
See the Notes section for details on what metadata is stored.
Parameters
----------
channel_dir : string
The directory where this channel is to be written. It will be
created if it does not exist. The basename (last component) of the
path is considered the channel's name for reading purposes.
dtype : np.dtype | object to be cast by np.dtype()
Object that gives the numpy dtype of the data to be written. This
value is passed into ``np.dtype`` to get the actual dtype
(e.g. ``np.dtype('>i4')``). Scalar types, complex types, and
structured complex types with 'r' and 'i' fields of scalar types
are valid.
subdir_cadence_secs : int
The number of seconds of data to store in one subdirectory. The
timestamp of any subdirectory will be an integer multiple of this
value.
file_cadence_millisecs : int
The number of milliseconds of data to store in each file. Note that
an integer number of files must exactly span a subdirectory,
implying::
(subdir_cadence_secs*1000 % file_cadence_millisecs) == 0
sample_rate_numerator : int
Numerator of sample rate in Hz.
sample_rate_denominator : int
Denominator of sample rate in Hz.
Other Parameters
----------------
start : None | int | float | string, optional
A value giving the time/index of the channel's first sample. When
`ignore_tags` is False, 'rx_time' tags will be used to identify
data gaps and skip the sample index forward appropriately (tags
that refer to an earlier time will be ignored).
If None or '' and `ignore_tags` is False, drop data until an
'rx_time' tag arrives and sets the start time (a ValueError is
raised if `ignore_tags` is True).
If an integer, it is interpreted as a sample index given in the
number of samples since the epoch (time_since_epoch*sample_rate).
If a float, it is interpreted as a UTC timestamp (seconds since
epoch).
If a string, three forms are permitted:
1) a string which can be evaluated to an integer/float and
interpreted as above,
2) a time in ISO8601 format, e.g. '2016-01-01T16:24:00Z'
3) 'now' ('nowish'), indicating the current time (rounded up)
ignore_tags : bool, optional
If True, do not use 'rx_time' tags to set the sample index and do
not write other tags as Digital Metadata.
is_complex : bool, optional
This parameter is only used when `dtype` is not complex.
If True (the default), interpret supplied data as interleaved
complex I/Q samples. If False, each sample has a single value.
num_subchannels : int, optional
Number of subchannels to write simultaneously. Default is 1.
uuid_str : None | string, optional
UUID string that will act as a unique identifier for the data and
can be used to tie the data files to metadata. If None, a random
UUID will be generated.
center_frequencies : None | array_like of floats, optional
List of subchannel center frequencies to include in initial
metadata. If None, ``[0.0]*num_subchannels`` will be used.
Subsequent center frequency metadata samples can be written using
'rx_freq' stream tags.
metadata : dict, optional
Dictionary of additional metadata to include in initial Digital
Metadata sample. Subsequent metadata samples can be written
using 'metadata' stream tags, but all keys intended to be included
should be set here first even if their values are empty.
is_continuous : bool, optional
If True, data will be written in continuous blocks. If False data
will be written with gapped blocks. Fastest write/read speed is
achieved with `is_continuous` True, `checksum` False, and
`compression_level` 0 (all defaults).
compression_level : int, optional
0 for no compression (default), 1-9 for varying levels of gzip
compression (1 == least compression, least CPU; 9 == most
compression, most CPU).
checksum : bool, optional
If True, use HDF5 checksum capability. If False (default), no
checksum.
marching_periods : bool, optional
If True, write a period to stdout for every subdirectory when
writing.
stop_on_skipped : bool, optional
If True, stop writing when a sample would be skipped (such as from
a dropped packet).
stop_on_time_tag : bool, optional
If True, stop writing when any but an initial 'rx_time' tag is received.
debug : bool, optional
If True, print debugging information.
min_chunksize : None | int, optional
Minimum number of samples to consume at once. This value can be
used to adjust the sink's performance to reduce processing time.
If None, a sensible default will be used.
Notes
-----
By convention, this block sets the following Digital Metadata fields:
uuid_str : string
Value provided by the `uuid_str` argument.
sample_rate_numerator : int
Value provided by the `sample_rate_numerator` argument.
sample_rate_denominator : int
Value provided by the `sample_rate_denominator` argument.
center_frequencies : list of floats with length `num_subchannels`
Subchannel center frequencies as specified by
`center_frequencies` argument and 'rx_freq' stream tags.
Additional metadata fields can be set using the `metadata` argument and
stream tags. Nested dictionaries are permitted and are helpful for
grouping properties. For example, receiver-specific metadata is
typically specified with a sub-dictionary using the 'receiver' field.
This block acts on the following stream tags when `ignore_tags` is
False:
rx_time : (int secs, float frac) tuple
Used to set the sample index from the given time since epoch.
rx_freq : float
Used to set the 'center_frequencies' value in the channel's
Digital Metadata as described above.
metadata : dict
Used to populate additional (key, value) pairs in the channel's
Digital Metadata. Any keys passed in 'metadata' tags should be
included in the `metadata` argument at initialization to ensure
that they always exist in the Digital Metadata.
