External Email - Use Caution looking further into the archives, I see that the -sdf flag can be used. I’m still uncertain about the -ngroups flag. I see at least a couple other users have asked about this but I don’t see a response. In the present case, if there are 60 slices and they are accelerated by a factor of 6, does one specify -ngroups 6 or -ngroups 10?
