An ODT file may also be a dialog theme used by OriginLab Origin, a data analysis and graphing application. It contains analysis dialog box settings that control how a dialog box receives, analyzes, and outputs data. ODT files are saved in XML format, but they are not meant to be opened outside Origin.
More Information
Scientists and engineers across a variety of fields use Origin to import, analyze, and graph data. While analyzing data, users can open various dialog boxes that manipulate data in different ways. These dialog boxes have many settings a user can customize.
If a user wants to save the settings they've entered in a dialog box, they can select the triangle button that appears to the right of the Dialog Theme field and select Save As... . This saves the user's current settings as a dialog theme, or ODT file.
Users can save multiple themes for the same dialog box, and they can select from those themes using the triangle button. Users can also choose to set a certain ODT file as a dialog box's default theme.
NOTE: Origin typically saves ODT files in the C:/Program Files/OriginLab/Origin<version>/Themes/Dialog directory.
How to open an ODT file
Origin ODT files are not meant to be opened by users. To select a theme for an Origin dialog box, open that dialog box in Origin and then select the triangle button that appears to the right of the Dialog Theme field.
