Reg:Transformation features in Enhydra octopus

Hi ,

    I am using Enhydra octopus for data loading.Can you please tell me what are all the trnforamtion feature provided by octopus.
    For example, if i want to do aggregate tranformations(SUM,AVG,MAX,MIN) then how to implement that?
Please provide me the solution. Its very very urgent.AS per the document i have tried replace and concat its working fine.But how abt filters,routers etc...

Important:I have posted three or four questions in different forums for various issues. But i didnt get any replies.I guess this is the correct place to post my octopus questions.I hope that i will get reply for this. :)
