./template.tex:172: Package pdftex.def Error: File `E1-1-eps-converted-to.pdf’ not found. [\centerline{\includegraphics{E1-1.eps} }]
./template.tex:394: Package pdftex.def Error: File `E1-2-eps-converted-to.pdf’ not found. [\includegraphics{E1-2.eps}]
./template.tex:417: Package pdftex.def Error: Eps – converted File ` no.e1-2 – – to.. PDF ‘not found. [\ includegraphics {E1-2. Eps}]

the solution:
First, add the macro package
\usepackage{epstopdf}
Second, compile from the command line
pdflatex –shell-escape template.tex
To complete.
