Dear all,

When I run qualscore.jar (version 1.0_2), the following error occurred, as 
has been discussed in 
https://groups.google.com/d/topic/spctools-discuss/nlYPIMrGHuI/discussion 
but did not provide further solution to the problem.

processing 20060427_digest_IPG2_7.mzXML...     18500 19000 19500 20000

So, what can I? Or any suggestion to using qualscore to filter tandem mass 
spectra.

Thanks.
