[CWB] question

[Stefania Spina]

Hello,
can anybody help me with a query that I'm trying to run on a CWB
encoded corpus?
The corpus has word, pos and lemma as positional attributes and <text
>and <s> as  structural attributes; is it possible to extract the mean
length of <s> in the corpus, in number of words?
Thank you very much for your help,
Stefania
