Table 1 Overall statistics of the RNAz screen. Initial filtering of Pecan alignments leaves roughly 50% as input for RNAz respectively to the ncRNA prediction. The distribution of RNAz hits does not show a chromosomal bias. We counted the number of predicted loci and their overall length at two probability thresholds (p > 0.5, p > 0.9) for normal and also randomized alignments. Obtained relative frequencies (given as percentages) can be interpreted as false discovery rates (FDR). As expected, the FDR decreases with a higher RNAz p-value.
