Seismic 3D interpolation: masked random traces

[kerim371]

Hi,

Based on 3D interpolation tutorial I'm trying to interpolate my 3D shots.

My data have random null traces. That means we can't say that for example x[N,:,:] are all null (zeroed / masked).
With that it becomes difficult to specify iava and iava1 indexes of not null traces.

So how can I specify not null traces if they are not contigous along any of the dimensions?

Could you share your attempt?
