Need further help to calculate seismic AVO attributes from common shot gather data

[abhash.kumar]

Hi,
I posted my request earlier to get some help regarding AVO attribute calculation from the common shot gather data. I am creating this post again to get further help. I created the 2D synthetic shot gathers using Seismic Unix with an assumption of perfectly flat layers in the model domain. Does anyone know or have any shell scripts that could be used to create CDP gather, NMO correction, and AVO attribute calculation from synthetic shot gather data? I would be very grateful for your help.

Best,
Abhash Kumar
