Hello everyone,

I am busy to find out how the staden-package calculates the consensus-QVs. 
I read the page "Consensus Calculation Using Confidence Values" but I 
didn´t find out so far how the Bayesian calculation works. I am specially 
interested in the question if one or two bases with a low QV (at a position 
with several bases of medium and good quality) can decrease the 
consensus-QV compared to the situation if this one or two bases of low 
quality weren´t there. I would just try if I had the equipment but I 
havn´t. Aside from this I´d rather know the theory than the result of an 

I appreciate any help.

best regards
