Copy number axis in sequenza result files are not fully resolved.

Question

[tanbiswas6]

Hi

I've used sequenza to infer CNV profile from WES data. However, in the pdf files which I got from sequenza analysis, the copy number axis is not fully resolved. Please see the following chromosome 1 plot in which the bottom plot is not easily understandable.

Can anyone please tell me what is the reason and how I can enlarge the copy number axis so that I can get the following kind of figure.

Thank you.
