LibreOffice and Apache OpenOffice are free open-source alternatives to Microsoft Office. The Writer word processor included with OpenOffice and LibreOffice is equivalent to Microsoft Word.

Writer allows users to write and format personal and business documents, such as resumes, letters, essays, and research papers. Writer saves users' documents in ODT files, which are similar to Word's DOCX files.

The Organization for the Advancement of Structured Information Standards (OASIS) maintains the XML-based OpenDocument standard. This standard is used by OpenOffice, LibreOffice, and other variants, all of which save documents as ODT files.

OOMMF is a public domain micromagnetics package that allows physicists to solve micromagnetics problems. When a physicist solves a micromagnetics problem, OOMMF produces an ODT file that contains tabular text data. Each table includes:

  • The solver iteration count
  • Nominal applied field
  • Reduced average magnetization
  • Total energy

Each ODT file begins with the line # ODT 1.0, to identify it as an ODT file. In addition to tabular data, ODT files may also contain the following tags:

  • Table Start: Used to segment a file containing multiple data tables
  • Title: Used to specify a table's title
  • Units: Used to specify data's units of measurement
  • Table End: Paired with a corresponding Table Start tag

ODT files may also contain comments, preceded by ##.

How to open an ODT file

You can open an ODT file in OOMMF (multiplatform). Doing so will visually display the data the file contains. You can also open an ODT file in any text editor, to view the data it contains as plain text.

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.
