Hello, I'd like to apply mb.long() function to min/max scaled (i.e. in [0,1]) timecourse data. I've read that mb.long() input data has to be of log2 kind. So does it make sense then to apply the algorithm to scaled data? Unfortunately I cannot take the log2 because zero is included. Many thanks in advance, Silvia v.d.
