 A while ago I had posted a question about amplified>
RNA experiment and  guidelines one should follow
during data analysis and Dr. Gentleman had suggested
that RNA digestion plot will be a good indicator for
deciding which samples should be used in data analysis
as it is important to comapre likes. For my
experiments,I think prima facie the plots look quite a
bit similar but since I am new to this area
I cannot estimate what should be range of difference
in slopes that one should tolerate while choosing the
comparable profiles. To give an idea of what I am
seeing I am attaching a postscript image and giving
the slopes at the bottom of this email. I will be
extremely obliged if somebody could provide me
further guidance so that I know I am on the right
track. Please let me know if I need to provide more
than the following information?
Here is the data: (I think sample # 8 seems to have
a slope that is different fro the rest!! Should it be
eliminated or one should observe the trend of the
