npTDMS is a cross-platform module for reading TDMS files as produced by LabView, based on the file format description at http://zone.ni.com/devzone/cda/tut/p/id/5696.
Data is returned as a numpy array, and if the data storage is contiguous then numpy's fromfile is used so that loading is very fast.
Typical usage might look like:
#!/usr/bin/env python
from nptdms import tdms
tdms_file = tdms.TdmsFile("path_to_file.tdms")
object = tdms_file.object('Group', 'Channel1')
data = object.data
time = object.time_track()
# do stuff with data
What Currently Doesn't Work
This module doesn't support TDMS files with XML headers and some data types, eg. strings, time stamps and extended floating point values.
Contributors/Thanks
Thanks to Floris van Vugt who wrote the pyTDMS module, which helped when writing this module.
