How to enter data for lilliefors test

Hi,
I am looking for a normality distribution test for small samples. Research has lead me to believe that the lillietest function will do the job, however I am unsure of how to out the data in? Effectively I have collected two EMG signals under two different conditions. Matlab help file indicates the input format is [h,p] = lillietest(x). Based on this should I perform two tests for normality each with two signals? i.e. x = condition one y = condition two?
Or should I put all data together and run the test for normality only once?
I appreciate any help or advice that can be offered. Thanks Dan

Hi Daniel, Yes, lillietest() takes a vector input, so you will need to input the signals one at a time.

Hi Daniel, from what little I know of your experiment, it appears to me that you need to run it for all four. I mean what would you conclude if you the two time series for the same condition gave different answers?
Also, you should some correction (Bonferroni for example) for your multiple tests.
