This is now fixed in the trunk. You'll have to make your own build of biojava.jar from the CVS tree to get correct(ed) pI values.

Well I try to calculate the isoelectric Point for all the peptides with de Expasy Calculator and I obtained: ALLIDLPV: Theoretical pI: 3.80 Molecular weight (average): 853.07 FDIYAGTPV: Theoretical pI: 3.80 Molecular weight (average): 982.10 SVLLMSAEI: Theoretical pI: 4.00 Molecular weight (average): 962.17 PTGDTTGYLANPEEV: Theoretical pI: 3.57 Molecular weight (average): 1563.64 My code is this: OBioSeq = ProteinTools.createProtein(Sequence); IsoelectricPointCalc OBioIsoc = new IsoelectricPointCalc(); double dIsoelec = 0.0; dIsoelec = OBioIsoc.getPI(OBioSeq,true,true); Thanks in advance Center of Molecular Biology.
