Can anyone tell me what is the meaning of m1-g #### genes?

Hi,

I ran Braker using RNAeq and protein hint evidences. I obtained gene models named jg - ##### and a few m1-g #####.
I have been looking for this nomenclature in the documentation with not luck.
Can anyone tell me what is the meaning of m1-g #### genes?

Thank you very much in advanced.
