Option saves a data set to a 32-bit integer .dat file. The limits for the 32 bit integer
2)
are handled in similar fashion to the 16 bit integer above.
Option saves a data set to a 32-bit floating point .dat file.
3)
When using your own software to handle a .dat file, you have to work out how many
bytes to read in. Each 32-bit value requires 4 bytes to handle the value. Thus, for
example, to read in a 32-bit .dat file consisting of 1024 data values, you would have
to read in 4096 bytes in total.
Internally data is stored as 32-bit float. Saving data to integer data files will result in
a loss of precision. Original data remains unaffected.
A configuration file contains the values that appear on the system's dialog boxes
whenever the application is launched, or whenever a configuration file is newly
loaded. Using configuration files is an easy way to tailor the overall application set-
up to suit particular experiments. Configuration files reside in the same directory as
the executable (.exe) of the application itself. The factory-supplied configuration file
(.cfg) contains typical default settings. Each time you start up the system, the
iXon .cfg is loaded automatically.
The Configuration Files menu item opens a further submenu with options
Load... and Save... that let you select or create configuration (.cfg) files:
Use Save... to store your current settings under a filename and in a directory of your
choosing. You can, if you wish, overwrite an existing configuration file.
Use Load... to select the configuration file you currently want to use. The system
will immediately use the settings in the newly loaded file.
