Mutually exclusive events in 294 cell lines (GSK set).

In the potential space of double genomic events totaling 34191 co-events, we identified events that co-occurred less than expected by chance. These correspond to the extreme left tail of the distribution in Fig. 2. Events that co-occur less than expected by chance are mutually exclusive (observed freq = 0; BOLD), or partially exclusive (observed freq>0). Events with the most significant P-values AND maximal differences are reported here. Italics indicate P-values [0.06–0.10].
