hg16-mm3-rn3-pt0
Collected and merged blocks of 100 bp 96% id between mm-rn-pt.

Compared human to blocks.
Computed probability of rejecting the null hypothesis of equal substitution rate in whole tree
* using a phyloHMM fit on phastCons conserverd regions
* alternative hypothesis: human branch has faster rate
* deleted all columns with gap characters from probability computation, maintaining only columns with a base in all four species.

Only blocks with probability > 0 of rejecting the null hypotheses are included.
