EMG Data processing for force validation

Hello,
I am using 4th Grand Challenge data for my research.
I have some question of using the EMG Data to validate the calculated Muscle Forces of an inverse dynamics model. Which processing I have to perform to use the data to calculate an activation signal out of the EMG raw data? Do you know recommended matlab functions for this?
Thank you

I'm unfamiliar with the data set you mentioned, but Arnold et al. describe their method for processing EMG in the following paper:

Arnold, E.M., Hamner, S.R., Seth, A., Millard, M., Delp, S.L. How muscle fiber lengths and velocities affect muscle force generation as humans walk and run at different speeds. Journal of Experimental Biology 216:2150–2160. http://nmbl.stanford.edu/publications/p ... ld2013.pdf (page 2152, "Experimental data" section, paragraph 2).
