Blank heatmap for peak bed file #21

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

ngs.plot.r -G hg19 -R bed -C hesc.H3k4me3.Rep1.sort.bam -E 
hesc.H3k4me3.Rep1_summits.bed -O testbed

What is the expected output? What do you see instead?

The avg. profile looks fine but the heatmap is blank.

It seems the R graphics::image has put a limit on the number of points to 
display. I'm not sure about the exact number of limitation but for a heatmap 
that contains close to 40,000 regions, it will display as blank.

False alarm. It is a problem with the Linux program that I use to view PDF 
files. If adobe reader is used, the heatmap looks just fine.
