26 DIAdem® DATA – Loading and Saving Data 04-19-00 DIAdem®
Saving and Opening Data Sets
Data in the Data area is only present during program runtime. It is deleted as soon as a new data
set is opened in DIAdem
®
DATA or when the program is terminated. To use this data in the
future you must save it to the hard drive.
Save Data as…
To save the data set, click on the corresponding symbol in the Tool bar. Save the edited data set
to the demo path (...\diadem\demo\dat) under the name example1.dat. The data set can also be
saved directly with its name, using the file menu.
A bit of theory: as soon as you have saved data, DIAdem
®
stores two files with the same names
on the data path: the actual data file, usually with the extension *.R32, and the associated header
file with the extension *.DAT.
The header file contains all the information required to open the (numeric) data files. The header
file contains not only the general data set description, but also all the information required to read
in the single channels of the data file(s). The data file contains the numeric data, saved in one or
more channels.
Delete all data
The whole data area is emptied with the “empty page” symbol in the tool bar.
In the following, the example file “Data.dat” should be loaded from the hard disk, because this
data is used in the following chapters of the manual.
Open new data file
Click on the Open symbol in the Tool bar. Choose the file data.dat, which has the demo path
(..\diadem\demo\dat). Confirm your selection with “OK”.
The newly opened DIAdem
®
data channels now appear in the overview. They are thus available
in the Data area to be used by other DIAdem ® devices.
Note: The last path [from which a data file was loaded]is used as a new user path in
DIAdem ® -DATA for the current session.
Apart from DIAdem
®
data files, other external data can be imported using the File menu. The
user can extend the list of available file formats by including appropriate GPI file import/export
filters. Information about these filters can be requested in the “Options – External file type info”
menu. You will find more details about the GfS Programming Interface GPI in the program help.
