It would be very helpful to tell us where the template is coming from.

Every command you are using with LaTeX has to be defined first. Some commands are available loading packages. One package i know, that defines something like that is hologo (\hologo{BibTeX}).

There are more undefined control sequences in your document. It might be easier using the simpler LaTeX-level to debug first.

Dear Sir,
I have installed the LYX 2.0, MIKTEX, JABREF, GHOST,2gsv to my system.
I have taken the template from LYX 2.0 > FILE > New from Template > IEEE Tran.

I have shown the screen shot, how I have taken template from LYX 2.0.

Oh, the direct LyX template. I am not a LyX user, so i cannot be of real help here. It is strange though, that the unmodified template gives errors like that.

We are a bit short on LyX users right now, so we have to wait.
ANother possibility would be to ask on the LyX users mailing list.

You could define the missing command in your document preamble (LyX menu, Document settings, preamble), for example:

Code: Select all

\newcommand*{\BibTeX}{\textsc{Bib}\TeX}

Auch schon gesehen in bibtex.web:

Code: Select all

\def\BibTeX{{\rm B\kern-.05em{\sc i\kern-.025em b}\kern-.08em
    T\kern-.1667em\lower.7ex\hbox{E}\kern-.125emX}}

I'm using LyX 2.1.3 and I just opened up the Ieee-TransMag template and clicked ViewPDFLatex and it compiled without errors. Try updating your LyX software and using the new template.
