Picks file composition

[InesHam]

Hello, I am using Refrapy to pick first arrivals and I can't identify the shot linked to the time arrival set at each line. Do you have some guides on how to understand the composition of the file?
Thank you.

Hello, I have the same issue, the geophone position ("g") isn't understable please help me

I found that in the x and y sections of a pick file, the values are sorted according to the geophone number 'g'. This means that if g = 2, the x-position of that geophone appears in the second position in the x and y arrays of the pick file.

So you can have all x position of the geophone and identify the shot linked to the time arrival set at each line. But i don't know why a specifi order is use for the pick file
