I hope you understand that it's not possible that we write scripts on demand to solve your scientific issues. I'd like to point you to the ​Seismic Handler users mailing list, maybe another user can help you.

If you have any detailed questions to certain commands or reports of unexpected behavior or errors you're welcome to open another ticket.

    initial v1  
    11I have got a deconvolution script for p to s RF but i need to develop the opposite one (S to P). I am new to this and I dont get the commands being used. I am posting the P to S decon script here......please suggest me how can I develop the my destined one...

    8 ! traces must be displayed by L,Q,T for each record. 
    9 ! the invers-filter is generated from each L-comp,  
    10 ! then the L-Q-T traces are folded with the invers-filter.
