Abstract
An approach was described for the automatic analysis of banded human B- and D-group chromosomes, represented by band transition sequences (BT-sequences), using Bayes formula in a simple way. The analysis considers the 14 BT-codes constituting the BT-sequence as being independent variables. Error rates of 6-8% in classification experiments and 3-4% in karyotyping experiments are clearly smaller than those reported by others using other methods. If the error rates of karyotyping are adjusted for errors in the basic material, they are reduced to 2-3%. The reason for the small error rate is presumably that the BT-sequences are superior to other methods for condensed band-pattern description. The method will be incorporated into a program system for automatic karyotyping.
