TDMS for Ruby

TDMS is a binary file format for measurement data. It was created by National Instruments.

• NI TDMS File Format
• TDMS File Format Internal Structure

National Instruments software such as LabVIEW, DIAdem, and Measurement Studio support reading and writing TDMS files. NI also provides a DLL written in C for using TDMS files on Windows.

TDMS for Ruby was written to provide a convenient way to work with TDMS files on Unix-like platforms.

Current State

This library is very early in development but is complete enough to read the example TDMS file that comes with NI DIAdem.

• Segments with interleaved measurements are not yet supported.
• Segments with big endian data are not yet supported.
• Writing TDMS files is not yet supported.

Fork

Aaron Ten Clay has a fork of this library that claims to support the segment types above, along with reading from streams instead of files, and other features.
