+of complex tissues.  DebCAM provides basic functions to perform unsupervised
+deconvolution on mixture expression profiles by @acronym{CAM, Convex Analysis
+of Mixtures} and some auxiliary functions to help understand the
+subpopulation- specific results.  It also implements functions to perform
+supervised deconvolution based on prior knowledge of molecular markers, S
+matrix or A matrix.  Combining molecular markers from CAM and from prior
+knowledge can achieve semi-supervised deconvolution of mixtures.")
