DetectionP v.1

This module assesses whether a given signal intensity measured by microarray is significantly higher than background signal due to non-specific hybridization (so-called "present" signal).  Furthermore, the module computes proportion of "present" probes in each sample (%P-call) based on a user-defined cut-off of detection p-value (default p<0.05).  It is recommended to use non-normalized data.
