        Tools to work with data generated by DAS systems.
        
        Overview
        --------
        This package provides a set of tools to read, manipulate and convert seismic waveforms
        generated by DAS systems. In particular, the ones saved in TDMs format.
        
        dasconv
        -------
        This utility lets you convert and manipulate seismic waveforms in TDMs format and export them into MiniSEED.
        
        Data acquired from experiments with DAS systems are usually stored in one folder. Files within this folder have names
        indicating the experiment and the start time of the waveforms saved. An example of the files generated in a test
        experiment is shown below. ::
        
            $ ls -l
            total 1577352
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:38 default_UTC_20190508_093735.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:38 default_UTC_20190508_093805.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:39 default_UTC_20190508_093835.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:39 default_UTC_20190508_093905.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:40 default_UTC_20190508_093935.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:40 default_UTC_20190508_094005.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:41 default_UTC_20190508_094035.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:41 default_UTC_20190508_094105.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:42 default_UTC_20190508_094135.409.tdms
        
        There, *default* is the name of the experiment and the rest is the start time with the following format:
        *experiment_TZ_YYYYMMDD_HHmmss.fff.tdms*.
        
        ``dasconv`` provides also a TDMS class which needs to receive one mandatory parameter to be instantiated,
        *filename*, which is actually the experiment name and how all file names in the containing folder start with.
        A detailed explanation on how to use it on your own programs can be found in the documentation.
        
        A typical help message from ``dasconv`` looks like the following: ::
        
            usage: dasconv [-h] [-l {CRITICAL,ERROR,WARNING,INFO,DEBUG}] [-d DIRECTORY]
                           [--start START] [--end END] [--chstart CHSTART]

        Examples
        ~~~~~~~~
        
        Export waveforms from channels 800, 802 and 804 starting at 2019-05-08T09:37:35.409000 until 2019-05-08T09:38:05.400000.
        The waveforms will be exported to MiniSEED format after being decimated by a factor of 5 (e.g. from 1000Hz to 200Hz). ::
        
            dasconv -d /home/user/test/ --start "2019-05-08T09:37:35.409000" --end "2019-05-08T09:38:05.400000" default --chstart 800 --chstop 805 --chstep 2
        
        Export waveforms from channels 0 and 1 from the beginning of the measurements until 2019-05-08T09:32:15.
        The waveforms will be exported to MiniSEED format after being decimated by a factor of 5 (e.g. from 1000Hz to 200Hz). ::
        
            dasconv -d /home/user/test/ --endtime "2019-05-08T09:32:15" default --chstart 0 --chstop 1
        
        Export waveforms from channels 0 to 4 from the beginning of the measurements until 2019-05-08T09:32:15.
        The waveforms will be exported to MiniSEED format after being decimated by a factor of 5 (e.g. from 1000Hz to 200Hz). ::
        
            dasconv -d /home/user/test/ --endtime "2019-05-08T09:32:15" default --chstart 0 --chstop 4 --decimate 5
        
        tdmsws (experimental)
        ---------------------
        tdmsws is a stand-alone implementation of the FDSN Dataselect web service, which is able to serve miniSEED data extracted
        from a folder with TDMS files.
        
        A typical help message from ``tdmsws`` looks like the following: ::
        
            % tdmsws -h
            usage: tdmsws [-h] [-mc] [-l {DEBUG,WARNING,INFO,DEBUG}]
        
            tdmsws is an FDSN Dataselect implementation to read TDMS files
        
            optional arguments:
              -h, --help            show this help message and exit
              -mc, --minimalconfig  Generate a minimal configuration file.
              -l {DEBUG,WARNING,INFO,DEBUG}, --log {DEBUG,WARNING,INFO,DEBUG}
                                    Increase the verbosity level.
        
        
        The "mc" switch creates a config file, which should be placed in the same folder as the TDMS files. The file includes
        all needed options and configuration variables which will be read by the software before being able to serve the data.
        The user is expected to edit this file and provide the basic information about the DAS experiment before running the
        service.
        
        One can see below a typical config file. ::
        
            [General]
            experiment = default
            loglevel = INFO
        
            [NSLC]
            network = XX
            location =
            channel = FSF
        
        The "experiment" variable refers to the first part of the filenames in the folder. For instance, in the example above
        all files will start with "default" and then a timestamp including the timezone (or UTC) will follow. ::
        
            $ ls -l
            total 1577352
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:38 default_UTC_20190508_093735.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:38 default_UTC_20190508_093805.409.tdms
            -rwxrwxrwx  1 user  staff   49965056 May  8 09:39 default_UTC_20190508_093835.409.tdms
        
        The variables "network", "location" and "channel" will be fixed to define the N.S.L.C code. Only the station will vary
        and it will always be a number referring to the stream number for the experiment. From the example above, the only valid
        code would be "XX.00001..FSF", "XX.00002..FSF", ..., "XX.00123..FSF" up to all available streams.
        
        Running the service
        ~~~~~~~~~~~~~~~~~~~
        To run the service you should "cd" into the folder with the TDMS files and make sure that there is a file called
        "tdmsws.cfg" with its variables properly configured. Then, you can simply call the program, which will start and run
        as a daemon. The service will listen to all requests in port 7000.
        
        Web service methods
        ~~~~~~~~~~~~~~~~~~~
        
        * query: The six required parameters "net", "sta", "loc", "cha", "start", and "end" are supported including their aliases. Errors are returned as specified in the standard.
        
        * version: returns the version number in text/plain format
        
        * application.wadl: returns details about implemented and supported options and parameters
        
        * queryauth: NOT implemented yet!
