ngs.plot.r gives flat graphs and no results

[Hannah Dixon]

Hi, 

I am running nags.plot.r on my indexed bam files for ChIP-seq data, however the output graphs are blank or flat and I'm struggling to find the reason why. Here are my commands and attached are some example of the output. 

for an individual sample: 

ngs.plot.r -G dm6 -R genebody -C /Volumes/T7_Touch/FASTA_ChIP/3_bam/ChIP_polIIcontrol_7.bam -O pol_test

for a pair of input and sample: 

ngs.plot.r -G dm6 -R genebody -C /Volumes/T7_Touch/FASTA_ChIP/3_bam/ChIP_UPF1_3.bam:/Volumes/T7_Touch/FASTA_ChIP/3_bam/ChIP_input_1.bam -O upf1_test3 

Any help is greatly appreciated.

Hannah
