[rsf-user] error in running sfhelm2D_forward

[Ajay Pundir]

I am trying to run the examples in"https://reproducibility.org/blog/2017/10/09/fwi-using-seislet-regularization/" but getting error "< marm.rsf /opt/madagascar-4.0/bin/sfhelm2D_forward source=csource.rsf > blend.rsf
sfhelm2D_forward: Using 1 out of 1 threads!
sfhelm2D_forward: Calculating frequency 1 out of 8 for 3.950620 HZ.

I have tried to run only sfhelm2D_forward too with marm.rsf and csource.rsf as inputs but it gets abort saying core dump. tried to window csources too. at different levels like for single frequency . by windowing shots n3=16 or even 8. but same result. dont know what is causing the problem.
