TITLE           Check the Quality of Sequences

OCCURRENCE      ARB_NT

DESCRIPTION     Takes sequences, a tree and a column statistic as input,
                and generates a short sequence quality output string, which
                will be stored into the database under a user defined key.

                First the sequences are split into different subsequences:

                        2 pieces:                 front and back half
                        5 equally sized pieces:   user defined sized pieces.

                The programs sums up the weighted mutations for each sequence
                part using a maximum likelihood technique.



NOTES           this feature is still under construction.
                Only sequences which are in the tree are used.

WARNINGS        Needs a really lot of computer memory!

BUGS            Does not delete the destination field of species not in
                the tree.
