The SDDS Toolkit is a collection of generic programs based on the Self Describing Data Sets (SDDS) file protocol. A twi file belongs to this software environment and provides data for one of its processing or analysis tasks.
The exact contents and role of a twi file depend on the SDDS Toolkit program that created it. It should therefore be handled with the toolkit rather than treated as a general-purpose document. The format is associated with the Linux and Unix versions of the SDDS Toolkit.
Open a twi file with the SDDS Toolkit program or command that created it on Linux or Unix. The toolkit may require the file as an input rather than opening it through a graphical file browser.
If the creating program is unknown, inspect the file with a text editor only to identify its contents; editing it may make it unusable for the toolkit.
If an SDDS Toolkit utility that reads the twi file provides an export or conversion operation, use that operation to produce another data format.
Otherwise, conversion depends on the SDDS Toolkit program that created the file and the structure of its data. Keep the original file when no documented export option is available.
