Hi - When iterating through the features of a ViewSequence I get the following exception: java.util.ConcurrentModificationException at java.util.AbstractList$Itr.checkForComodification(AbstractList.java:445) at java.util.AbstractList$Itr.next(AbstractList.java:418) at org.biojava.bio.seq.MergeFeatureHolder$MFHIterator.next(MergeFeatureHolder.java:211) at genesystem.GeneSysTools.initializeSystem1Model(GeneSysTools.java:117) at genesystem.GeneSystem1.main(GeneSystem1.java:53) I am not sure why this is happening ... I don't think the problem is at my end but you never know Mark ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Mark Schreiber Ph: 64 3 4797875 Rm 218 email [EMAIL PROTECTED] Department of Biochemistry email [EMAIL PROTECTED] University of Otago PO Box 56 Dunedin New Zealand ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ _______________________________________________ Biojava-l mailing list - [EMAIL PROTECTED] http://biojava.org/mailman/listinfo/biojava-l
