Have you found a way out so far? If so, can you share with me? I did a little research, and find that the reason is possibly caused by lyx only run latex multiple times, as is set in default in the converter from latex to dvi. This is incomplete to run feynmf since it requires latex and then mf and then latex again. The way(not so nice) I found is to change the converter to feynmf, then when you write the document and want to produce pdf view, click on compile to dvi first(the button calls feynmf to generate the necessary .tfm and .tn file), and then click produce pdf(this button uses the readily generated .tfm and .tn files to help generate the right pdf file). Most of the time, it will give the right pdf.
BTW, I use lyx 1.6.*** Real87 wrote: > > Hi > > I'm trying to produce Feynman diagrams using LyX.
