# plot correlation between several bam files

I have several mab files from medip-seq. they supposed to be replicates and I have to draw their correlation. First I used multiBamSummary from deeptools to merge all the bam files based on bi/bed. Now when I am using the plotCorrelation I do not get any file. the argument is :

plotCorrelation --corData myMultiBamSumary.npz --corMethod spearman --whatToPlot scatterplot --skipZeros --removeOutliers --plotFile Myplot --plotFileFormat pdf


Is that the correct strategy to pot the correlation? Is there any suggestion?

Thanks alot
