    Protocol
    Two independent chromatin immunoprecipitations (ChIPs) were performed using two different anti-twi antibodies (FBrf0049336, FBrf0195237). These ChIPs were compared to two independent mock ChIPs using rabbit pre-immune sera, as previously described (FBrf0202481).
    Chromatin was prepared from formaldehyde-fixed embryos as previously described (FBrf0202481).
    Mode of Assay
    Immunoprecipitated chromatin was analyzed by Affymetrix GeneChip Drosophila Tiling 1.0R array

    Data analysis
    Peaks were called with TileMap software (v1) after quantile normalization. For each enriched region, probe intensity peaks were identified as extrema on a smoothed curve of the log2-ratio signal. Finally, 200 bp regions centered on identified extremas were defined. Peak calls were lifted over from Dmel_Release_5 to Dmel_Release_6 using the NCBI Genome Remapping tool.
