Two beginner question again.

1. What is the difference between mkanalysis-sess and mkanalysis-sess.new? which one should be preferably used and why?

2. What is the best way to exclude trials from the analysis:

    a) in the paradigm file define them as a separate condition and this way include them in the GLM analysis and later on ignore them in the contrast analysis?

    b) exclude the time points of that trial in the tpexclude.dat using the tpexclude flag?

    c) another way that I have not thought of?

Thanks,

Maryam
