Description
The PCA calculation uses ScoreMatrix.computePairwiseScores(String[]), but the tree uses the ScoreModelI for computing matrices, which works on an alignment view rather than the stringified visible region.
As a further refinement toJAL-2379, PCA should use the same interface (which allows input data recovery) and the ScoreModelI interface updated to provide a MatrixI instance.
