What it does
------------

Rscript for calculating average PolII occupancy and FDR for RNA Pol II DamID datasets, based on original algorithms developed by Tony Southall.
The script processes datafiles in gatc.bedgraph or gatc.gff format, such as those generated by damidseq_pipeline.

Differences between RNA pol II DamID and RNAseq
-----------------------------------------------
Although both are methods for transcriptional profiling, please be aware that there may be differences between these two methods. In particular, transcript abundancy as assessed through RNAseq will depend on transcript stability, whereas RNA pol II occupancy may provide a better indication of transcription levels.
