I have put the Wiener filter scripts into  /opt/rtcds/caltech/c1/scripts/Wiener/  .  They are under version control. 

The idea is that you should copy ParameterFile_Example.m into your own directory, and modify parameters at the top of the file, and then when you run that script, it will output fitted filters ready to go into Foton.  (Obviously you must check before actually implementing them that you're happy with the efficacy and fits of the filters). 

Things to be edited in the ParameterFile include:

• Channel names for the witness sensors (which should each have a corresponding .txt file with the raw data)
• Channel name for the target
• Folder where this raw data is saved
• Folder to save results
• 1 or 0 to determine if need to load and downsample the raw data, or if can use pre-downsampled data
  • This should probably be changed to just look to see if the pre-downsampled data already exists, and if not, do the downsampling
• 1 or 0 to determine if should use actuator pre-weighting
• Data folder for measured actuator TFs (only if using actuator pre-weighting)
  • Actuator TFs can be many different exported text files from DTT, and they will be stitched together to make one set of measurements, where all points have coherence above some quantity (that you set in the ParameterFile)
• Coherence threshold for actuator data (only use data points with coherence above this amount)
• Fit order for actuator transfer function's vectfit
• 1 or 0 to decide if should use preweighting filter
• zeros and poles for preweighting filters
• 1 or 0 to decide if should use lowpass after Wiener filters (will be provided corresponding SOS coefficients for this filter, if you say yes)
• Lowpass filter parameters: cuttoff freq, order and ripple for the Cheby filter
• New sample rate for the data
• Number of Wiener filter taps
• Decide if use brute force matrix inversion or Levinson method
• Calibrations for witnesses and target
• Fit order for each of the Wiener filters

I think that's everything that is required.
