Hi Manu, ah yes indeed they are similar. I found this tool http://smithlab.usc.edu/plone/software/librarycomplexity after asking the question, and it did exactly what I wanted, in the context of high throughput sequencing. Thank you for your reply and help.
How To Create A "Discovery Plot"
Hello all,
I just had a question on how to create a "discovery plot", which is a plot to show the detection of genes as a function of sequencing depth.
An example of a discovery plot is figure S5 of this document: http://bloodjournal.hematologylibrary.org/content/suppl/2010/10/19/blood-2010-07-293332.DC1/Document1.pdf
Is it simply a matter of randomly sampling reads, checking which gene this read maps to and tallying to see if this gene was already reported or not?
Thank you in advance,
Dave

Hi Dave, I'm not sure, but this looks to me very similar to "rarefaction curves" for which you will find a ton of tools.
