Oscar class cannot load OSCAR IC format.

[LucasConstantin]

When trying to load a SMASH_IC.oscar file with the Oscar class, it throws the error Traceback (most recent call last): File "/mnt/c/Users/lucas/Desktop/Masterarbeit_project/old stuff/densities.py", line 76, in <module> oscar = sparkx.Oscar(path, events=event_number) File "/usr/local/lib/python3.9/dist-packages/sparkx/Oscar.py", line 259, in __init__ self.set_particle_list(kwargs) File "/usr/local/lib/python3.9/dist-packages/sparkx/Oscar.py", line 466, in set_particle_list raise ValueError( ValueError: First line of the event is not a comment line or does not contain "out". This is because the Header of the IC file looks like this:

#!OSCAR2013Extended SMASH_IC t x y z mass p0 px py pz pdg ID charge ncoll form_time xsecfac proc_id_origin proc_type_origin time_last_coll pdg_mother1 pdg_mother2 baryon_number strangeness

This is odd. Which branch/version did you use I can successfully read SMASH IC files like this:

#!OSCAR2013Extended SMASH_IC t x y z mass p0 px py pz pdg ID charge ncoll form_time xsecfac proc_id_origin proc_type_origin time_last_coll pdg_mother1 pdg_mother2 baryon_number strangeness

as IC reading is implemented. I used version 1.2.1

Actually I don't get the error at all. The header of the IC is exactly like any SMASH header, that's why before event processing the first 3 lines are dropped, and then the event line is processed. I would double check that the correct file is read in and not corrupted.
