On Off switch for loaded cells

Hey everyone, I currently have plantar pressure data during continuous running and wanting to write a script which will allow me to see which pressure sensor cells are loaded at the point of initial contact. For this I would like to split the foot into three segments (0-32, 33-66, 67-100%). So would I be best using an on off script but then I'm not sure on how to adapt it.

What is your question? What is an "on off script"? How are the data available - as files or do you obtain them from a serial connection to an EMED system? Splitting a foot in 0-32% and so on is not trivial: Note that all you have is the pressure distribution to a certain time. There is not complete shot of the foot and you cannot easily "sum" the different frames to a complete picture.

You find many publications concerning a classification of feet using the pressure distribution. But this is a Matlab forum. Please ask a question, which concerns the Matlab part of the problem.

Sorry maybe I phrased it poorly, the data is in files and I want to create a script that will show me which part of the foot is loaded at certain stages during the gait cycle. So it when on it should show me the loaded cells but when off there will be no cells loaded

How do you define "part of the foot" if all you have is the temporal development of the pressure under the sole? Is this an EMED system? The corresponding software inlucdes some sophisticated methods for dividing the foot into segments.

While this is an interesting problem in the fields of orthopedics, this is a Matlab forum. Do you have problems with the implementation?
