10.3 Split
Although RTDAQ does not support the older “mixed-array”
group of Campbell Scientiffic dataloggers (the CR10X, CR23X,
or CR510), the Split application included with RTDAQ is the
same one included for use with LoggerNet and other Campbell
Scientific support software. Because of this, the documentation
included here contains references to mixed-array data file
processing within the Split program, and also the Edlog program
editor. For most RTDAQ implementations these references can
be ignored. NOTE
Split is a tool that works with output data files (*.dat) collected from Campbell
Scientific dataloggers. It is used to post-process data from either mixed-array
or table-based dataloggers.
Split can create reports based on collected data by filtering data based on time
or conditions. It can generate statistics, perform calculations, reformat files,
check for data quality (limit testing), and generate tables with report and
column headings. It can also handle the time synchronization necessary to
merge up to eight data files.
10.3.1 Functional Overview
Split is a tool to analyze data collected from Campbell Scientific dataloggers.
Its name comes from its function of splitting out specific data from a larger
data file. Originally, Split could only process mixed-array files, and it was
used to “split” the different arrays – typically different time intervals – of a file
into separate files (e.g., for hourly versus daily data).
In addition to splitting out mixed-array data, Split can filter output data based
on time or conditions, calculate statistics and new values, reformat files, or
check data quality (limit testing). Split can generate tables with report and
column headings, as well as time synchronize and merge up to eight data files.
Input Files (maximum of eight) are read by Split, specific operations are
performed on the data, and the results are output to a new Output File or a
printer. Split creates a parameter file (filename.PAR) that saves all of your
settings such as which data files are read, what operations are performed on the
data set, and where the final results will be saved. The parameter file may be
saved and used again.
Input Files must be formatted in Printable ASCII, Comma Separated ASCII,
Field Formatted ASCII, Final Storage (Binary) Format, Table Oriented ASCII
(TOACI1 or TOA5), Table Oriented Binary (TOB), or Raw A/D data (such as
the results of a burst measurement).
Split can be used to convert a file of one format to a different format. For
example, a Table Oriented ASCII file can be converted to the Comma
Separated ASCII format used in mixed-array datalogger data files. This is
useful to convert table-based data files to work with applications that were
written to work with mixed-array files.
