Converting to DiaNN .tsv library format

[Arthfael]

We would be interested in converting the HDF libraries created by alphaDIA to DiaNN-like .tsv libraries. Is there any way to activate an option to output such a file format?

Alternatively, I would perform the conversion myself, except I am afraid that I may have too little information in the file:
I have managed to parse a HDF library file, but am rather confused as to the 2 fragment tables, fragment_mz_df and fragment_intensity_df: each has only 4 columns, if I read correctly, the first table contains the m/z for 4 fragment ions (2 each b and y), and the other the corresponding ion's intensity, correct? Why not include more fragment ions, is 2 each b and y really enough? Is there a way to force alphaDIA to include more fragments?

In addition, each precursor has 4 columns named i_0 to i_3: what are these?
