I plotted a histogram of RPKM value and this is what I got:
The median is about 36, but goes from 0 to 140K. So, I guess RPKM of 50 is pretty solid as you suggested, but what I do with low RPKM values? 1 or 2...? Where can I put a cutoff? Is it safe to say that under 10, it is a weak expression, 10-100 is "normal" expression and over 100 is high expression?
Thanks again,
TP
