The error message which states that continuous data should be standardized prior to use with SUMO currently does so after testing whether the mean and sd for the data are 0 and 1 respectively. -atol allows for tolerance in that test, but the error message when that fails would be more helpful if it told the user what the maximum deviance from the expected values were (rather than reporting the average of the mean and sd for all features).
