Hi

Just thinking out-loud here, which can be a painful process...

So MDS/PCA is an exercise in dimension reduction.  Therefore, if we
reduce the dimensionality of the dataset to few(er) dimensions which
explain most of the variability, then order the data set by those
dimensions, then that will place together genes (in the list) which are
behaving similarly - is that what you are suggesting?
