SECTION 4. SPLIT
4.1 OVERVIEW
SPLIT is a general purpose data reduction
program. Input files (maximum of 8) are
accessed by SPLIT, specific operations are
performed on the data, and the results are
output to an OUTPUT file. When SPLIT is
loaded, a list of prompts/questions are brought
to the screen. When answered, these prompts
define what files are accessed, what operations
are performed, and what file the results are
output to. The completed set of prompts with
instructions may be saved as a parameter file
(name.PAR). The parameter file may be called
into SPLIT for future use.
Input files (Section 4.3.1) must be formatted in
Printable ASCII, Comma Separated ASCII,
Field Formatted ASCII, Final Storage Format, or
Raw A/D data.
Output files generated by SPLIT are Field
Formatted (default) or Comma Separated
ASCII.
SPLIT applications include: data processing,
file reformatting, data quality checking (limit
testing), table generation with report and
column headings, time synchronizing and
merging of up to 8 files, and data selection
based on time or conditions.
SPLIT lends itself to experimentation. The
OUTPUT is displayed on the screen, giving
immediate feedback as to the affect of changes
or new entries to the parameter file. The input
file is not affected by SPLIT.
NOTE: Examples shown in this section
may include square brackets. These
brackets (i.e. []) must be included when
shown.
4.2 GETTING STARTED
SPLIT can be run from the command line or
from FILE | REPORTS in PC208E. Enter
'SPLIT' on the command line to load and
execute the program. The PC must be logged
onto the disk and directory containing SPLIT or
the appropriate "path" must be specified per the
PC-DOS Manual. As soon as SPLIT is loaded,
it requests information necessary to find,
process and store the data specified. Once this
information is supplied, it can be saved in a
parameter file for later use.
Type 'SPLIT' on the command line after the
drive prompt. SPLIT will load and display the
following:
Name(s) of input DATA FILES(s):
Name of OUTPUT FILE to generate:
START reading in:
STOP reading in:
COPY from:
SELECT elements #(s) in:
HEADING for report:
Enter and/or edit entries to the right of the
colons. Type in the name of your file that
contains the datalogger data and press return.
We will not enter additional parameters at this
time. Press the F2 key to display command
options at the top of the screen (Section 4.6).
They are EDIT, RUN, SAVE, QUIT, and LOAD
new parameter file. Select an option by
pressing the first letter of the command or by
using the arrow keys to move the cursor to the
option you want and then pressing return.
Press 'R' for RUN and SPLIT will put your raw
data file in columns on your screen.
4.3 SPLIT PARAMETER FILE ENTRIES
4.3.1 NAME(S) OF INPUT DATA FILE(S):
Enter the name(s) of the input file(s) on this line.
Input files must be formatted in Comma
Separated ASCII, Final Storage Format, Field
Formatted ASCII (SPLIT default output format),
Printable ASCII, or Raw A/D data (refer to
special Burst Mode Instruction in Campbell
Scientific datalogger manual).
Table 4.3-1 provides an example of Printable
ASCII, Comma Separated, and Field Formatted
input file types. The data in the various formats
are identical. Each line of data represents an
"Output Array", starting with an Output Array ID
(in this case 115). Each data point in the
Output Array is referred to as an "element".
The element number is given in the Printable
ASCII format, and implied in the other formats.
Data presented in Table 4.3-1 is used for
example purposes in Sections 4.3.3 through
4.3.5.
