Particle Weights and Injection from a file

[PhysicsDan]

Hi,
WarpX looks great - thanks for the continuous development.

I have been reading the docs regarding injecting particles from a file. From what I understand (correct me if I'm wrong) the weight of the particles is determined by the values set for the species.q_tot and species.charge which are both scalars, which would mean all the particles would have the same weight.

Is it possible to instead define the particle weight in the openPMD file which you read position, momentum, etc from so that each "macro" particle could have a different weight?

Update
I have noticed here that there seems to be a way to read directly from the openPMD file.

The openPMD format for ED-PIC is available here.

Thanks,
Daniel

Summary:
I was facing a issue which has been fixed in a recent pull request. For setting the weightings of particles from files you can use the ED-PIC extension of the openPMD format which you can view the details of in this github repo.
