[Biojava-dev] Isoelectric point calculation alteration??

[Warren, Jonathan]

Hi

I've used the proteomics package in biojava recently and found that the
source code I had hasn't been modified since this mail in July last year
http://www.biojava.org/pipermail/biojava-dev/2003-July/000744.html maybe
someone could check that it has been changed as I can't easily access
CVS through our security

Important part of message here - relates to IsoelectricPointCalc.java  :

You're right. The problem is actually in the choice of bounds I used. It
expects an answer between 1-13 for pI. In this case, the answer is
probably beyond 13. I suggest using:- double pI =
BinarySearch.solve(0.3, 13.7, 0.001, computeObj); That's one heck of a
basic protein ;-) Regards, David Huen
