1. What it does
- tdms_to_mat.py is a python script that converts a tdms file to a .mat file.
- tdms_to_mat_many.py converts all the tdms files in a folder

Given the name of the folder containing the file and its timecode, it will automatically read:
	- folder/analog-timecode.tdms
	- folder/encoder-timecode.tdms
and write the file
        -folder/data-timecode.mat

2. How to use it
line 8: write in the local binaries's folder (tdms\bin)
line 66: write the name of the folder containing the tdms
line 67: write the file's timecode
line 75: comment or uncomment the plot(data) depending on needs

5. Development notes
There's a couple of tdms converters for python and Matlab but they all assume 32-bit data. They worked fine on tdms
 files generated by Labview, but crashed on the 24-bit data generated by DAQmx.  National Instruments recently made available a c-binary library to 
read/write tdms files, so I used ctypes to write a Python wrapper around the most critical calls.
