Section 5. Split
A maximum of eight input files may be processed by Split at one time.
Additional input files are added using the EDIT | ADD DATA FILE menu
option. Split looks for a file extension of .DAT if no extension is specified. If
the Input File does not exist, an error message is displayed when RUN | GO is
selected from the menu options.
For instance, to process two files named TEST.DAT and TEST_1.DAT the
user would select TEST.DAT and TEST_1.DAT as Input Files. Two blank
input file templates will be generated. To change from one template to the
other, click the appropriate tab on the bottom of the screen. Both templates
must be completed before Split will process the data. To merge different
output arrays from the same input file into one array, open the data file once
for each different array.
5.3.1.1 File Info
In most instances, Split automatically recognizes the type of data file it is
reading when using Auto Detect in the File Info field. However, there are two
exceptions for which you should choose the appropriate option manually:
•
Reading Raw A/D Data from Burst Measurements
To read this type of data and convert it to ASCII, select Burst Format in
the File Info box. Once Burst Format is selected, the Number of Values
in Each Burst window in the Offset Menu will become accessible. Enter
the number of elements in each Burst. This number does not include the
array ID number or calibration data.
•
Reading Data in Final Storage (Binary) Format
If the data is in binary format and Start and Stop Offsets are used, Final
Storage (Binary) Format must be selected in the File Info field. This tells
Split that the file must be decoded as Final Storage before counting the
bytes. If Offsets are not used, Auto Detect may be chosen and the file
will be processed correctly.
5.3.1.2 File Offset/Options
Start Offset
None
Select his check box to start reading the input file from the beginning.
Last Count
Each time Split runs a parameter file, it keeps track of the number of bytes
it read from the input file and saves this information in the parameter file.
Split can then start where it last left off. This is done by clicking the
Offsets
button and selecting the Last Count option. This feature may be
used to process only the new data from a file in which new data are being
appended periodically to the data file.
