Dear MG5 authors I am doing some FO calculation in z+j process ,and have two questions regarding that. 1) I wrote my analysis in fortran and got my histograms but when i wanted to generate the LHE file (just to double check) i get the following error (i tried v3.2.0 & v3.1.1 and i tried ttbar production but still the same error, see down below): 2) For every channel in z+j, i managed to obtain the data values (thanks Matteo) for each observable. My question is: does each channel contribute equally to the overall histogram or not? All the best, Hamza.
