fastq comment line

[phpeters]

Hej, thanks a lot for the tool, I really love it! But I have one question I couldn't find a proper way to solve it: How can I work on the third line in a fastq file (the +-comment line)? When manipulating fastx one can access the 4 variables 1:name 2:seq 3:qual 4:comment, of which the $comment-variable does not mean the comment line but everything behind the name in the read-header. Is it possible to access the values in the comment-line though?

Thanks a lot and best regards! Philipp
