Hi Raffaele,

thanks for the message. I'm aware of this problem and in fact there are some 
other locations in the code that have the similar problems. I have fixed those 
too and the amended version will soon be on Bioc-Devel.

Note that a problem has arisen with PLM normalization. Avoid it at the moment 
until I fix it.

After thorough testing I shall see if I can fix the release version. Sorry about 
the errors,
