First of all, all the files that are not the one you made have to be removed from the branch. Then let's give a better name to the modified file like fluka_to_edm4hep.py

In lcio.txt there are some collections that are not in the edm4hep.txt.
There are no parameters in lcio.txt (at the end of the file) but this may be the conversion LCIO -> EDM4hep, I'm not sure, we should also make sure those are also there

I agree with Juan, that the missing parameters in lcio.txt must be a problem of the lcio2edm4hep conversion script. But since it is a separate tool that is not part of this PR, we can investigate it later.
A more relevant issue here is in the edm4hep.txt file, specifically in this part:

std::string parameters
Key                           Value 
--------------------------------------------------------------------------------
FilesPerEvent                 []
InputFiles                    []

There are two problems:

1. no values are assigned to the FilesPerEvent and InputFiles keys
2. they are stored in the file as std::string parameters, while in reality they represent integer numbers, and should be visible under the int parameters section.

@jmcarcell it looks like podio detects by itself, which type to use, which apparently doesn't work well with python integer types. Do you have an idea how to force it to use the integer type?
