Distancer: -d "pearson" option doesn't print raw Pearson values
Pearson values are expected to range from -1.0 to 1.0. But when supplying Distancer with parameters: Distancer -i GSE9963.GPL8300.pcl -o /tmp/t1.dab -z -d "pearson" The Pearson stored in the dabs are always distributed from 0 to 1.0.
Upon looking at the code, it seems that this is because the parameter IMeasure::EMapCenter is always on in Distancer.cpp.
Should have an option in Distancer to turn this centering behavior off, especially for the vanilla Pearson operation.
