Force plate zero offset

I have collected data from a force plate with the use of matlab. But initially, the signals of 6 channles were set slightly below or above the zero.
I want to know how to set it zero offset with the use of matlab code.

Typically, you would do a reference measurement (with no load on the force plate). Take that measurement and compute the average (mean) of it. Then after taking your actual measurements, subtract the average you computed before with the no-load condition.

I'm not sure that's physically possible. You have to physically have nothing on the forceplate for the "no load" condition, and then do the experiment. The way I used to do the experiment, was to record the no load condition at the beginning of the test and store the data. Then after doing all the experiments, I postprocess by subtracting the no-load data from all of my test results. Another way is to run the test with no load for the first few seconds. Then when you post process, take the mean of the first few seconds and subtract it from the rest of the experimental data.
