Sure, but first i would like to make something clear. The original document was written at work (with the ABTN2 keyboard), I continued to work on it at home (english keyboard) and today I sent it back to work. Then the problem with the accents appeared. Here is a small sample of the output in lyx: "H uma estrutura secundria de RNA localizada na regio intergenica entre pstS e pstC, cuja presena foi demonstrada pela tcnica de extenso de primer" But it should be: "Há uma estrutura secundária de RNA localizada na região intergenica entre pstS e pstC, cuja presença foi demonstrada pela técnica de extensão de primer" Beny -- %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Beny Spira Departamento de Microbiologia Instituto de Ciências Biomédicas Universidade de São Paulo Av.
