Table 1 Significant bins of the overlap test between H3K27me3 segments and SINE repeats under various null models

From: The Genomic HyperBrowser: inferential genomics at the sequence level

Tracks to randomize Preserve total number of base pairs covered Preserve segment lengths, but randomize position Preserve segment and intersegment lengths, but randomize positions
H3K27me3 10/19 1/19 0/19
SINE 10/19 5/19 4/19
H3K27me3 and SINE 10/19 5/19 4/19
  1. The number of significant bins of the overlap test between H3K27me3 segments and SINE repeats under different preservation and randomization rules for the null model. The test was performed in 19 bins on mouse chromosome 17, with the MEFB1 cell line. (Use of the MEFF cell line gave similar results; Table S2 in Additional file 1). In this case, less preservation of biological structure leads to smaller P-values. Also, randomizing the SINE track gave smaller P-values than randomizing the H3K27me3 track (or both).
