I tried to convert a file to seg-y and it worked, but when I try to go back to rsf i lose some information.
In particular I have this file:
esize=4 type=float form=native label="Velocity"
n1=1001 d1=0.004 o1=0 label1="Time" unit1="s"
n2=2142 d2=1 o2=1 label2="Velocity" unit2="s"
n3=1 d3=1 o3=1
2144142 elements 8576568 bytes
that I converted to seg-y, but going back to rsf i lose n3=1, d3=1, o3=1 and it gives me an error when I try to visualise my file.
How can I solve this problem?

What is the error when you try to visualize it?

You can put additional parameters in the file with sfput http://ahay.org/wiki/Guide_to_madagascar_programs#sfput

This is the file rsf that I create from the seg-y, that should be the same as the first one that I put in the upper comment

To view it, you need to create a Result command in your SConstruct file. It may look like

Result('v2stack','grey title=Stack')

I'm going to write here because the other issue is closed.

Sorry for the mistake, NMO works well with multiple CMPs.
I'm having problems with pradon. How can I extend it to all the cmps and how can I have a nice final image with the multiples attenuated?

And when I try to visualize the cmps of seismic.segy, so the ones with no processing applied to them, I obtain this image. Why it is so strange?

Thank you very much for the support

To view results, run scons inside the geom directory:

cd geom
scons view
