Cnv Visualisation

Dear All, I need to visualize my CNV data in the same way as it in this page. Could you please help me out???

http://www.biomedcentral.com/1471-2164/12/414/figure/F1

Input format is something like this:

Chr StPos EndPos sizeofCnv(kb) CNV(loss/gain) SDoverlap(0/1)

Thanks a lot

It looks like they might have just generated a horizontal stacked bar graph. Each stacked segment can be defined with your raw data. So a CNV segment will just be another bar in the same stack.

You can probably use R to generate something similar. You'll have to write some scripts to transform your data into a format suitable for R.

Personally, I like using [?]ggplot2[?] to generated my graphs.

Agreed - looks like a custom R script to me.
