Are you using data analysis software (e.g., SPSS or R) to analyze this data? If so, I would wonder why you don't just do the scaling with that software (R has a "scale" function). In any case, a quick look at some of the LIBSVM documentation showed the syntax to be like:
Code:
svm-scale -s scaling_parameters train_data > scaled_train_data
Really, you can't get anymore simple than that. Read the online documentation for what flags and parameters you can use to satisfy your request.
