Hi Richa,
I was not able to get exactly what I wanted. As you know the g_sham output
does not give you the energy Vs PC information, rather it gives energy Vs
bin index information. So, the problem is how to transform bin index
information into PC values.
As I was not much interested in exact PC values, so I have tried to find
out the PC values where the system spends most of the time (from the PC Vs
time plot), once we find those PC values, then one can approximately map
minimas in 1-d FEL to the corresponding approximate range of PC values.
Again I will say this not the most accurate way of getting PC Vs energy
information. For getting exact information there is no way to get it
directly from g_sham without post processing its output as suggested by Dr.
Justin.
