[Tex/LaTex] Using BibTeX with LyX: errors in auto-generated .bbl

bibliographiesbibtexerrorslyx

I've been puzzling with this for hours now and I can't solve it.
I'm using LyX for my article and I made a BibTeX file with JabRef. I inserted the BibTeX bibliography into LyX, but when I try to compile, errors appear:

Multiple "Missing $ inserted.", "Missing } inserted." and "Extra }, or forgotten \endgroup."

The first error says:

Missing $ inserted.
\newblock http://www.nasa.gov/mission_
                       pages/stereo/multimedia/deploy.html

They all refer to lines in the auto-generated .bbl file.

The same problem occurs when I export LyX to LaTeX and compile it there (also with different encodings). I've read some things about BibTeX encoding, but I can't figure it out.

I'll post some of the BibTeX below:

@INPROCEEDINGS{MSOptimizationEvaluation,
  author = "Jens N. Kaftan and Andr{\'e} A. Bell and Til Aach",
  title = "Mean Shift Segmentation Evaluation of Optimization Techniques",
  booktitle = "Proceedings of the Third International Conference on Computer Vision Theory and Applications, VISAPP 2008",
  year = "2008",
  pages = "365-374",
  address = "Funchal, Madeira - Portugal",
  month = "January 22-25",
  publisher = "INSTICC - Institute for Systems and Technologies of Information, Control and Communication"
}

@CONFERENCE{HDTV_AxiVision,
  author = "Kawakita, M. and Kurita, T. and Kikuchi, H. and Inoue, S.",
  title = "HDTV axi-vision camera",
  booktitle = "Proc. of International Broadcasting Conference",
  year = "2002",
  pages = "397-404"
}

@ARTICLE{MarrPoggio,
  author = "Marr, D. and Poggio, T.",
  title = "A computational theory of human stereo vision",
  journal = "Proceedings of the Royal Society of London. Series B, Biological Sciences",
  year = "1979",
  volume = "204",
  pages = "301-328",
  number = "1156",
  issn = "0080-4649",
  publisher = "JSTOR"
}

@MISC{jEDISON,
  author = "Pangburn, Brian E. and Ayo, Jonathan P.",
  title = "Koders - Source Code Search Engine",
  howpublished = "http://www.koders.com/info.aspx?c=ProjectInfo\&pid=1ZLCBNBRKBWSX9KL1VF3ZA989H\&s=Region",
  year = "2002",
  timestamp = "2011.01.06"
}

Any ideas?

Best Answer

The problem is with the underscore in the url. Try using something like

howpublished = "\url{http://www.nasa.gov/mission_pages/stereo/multimedia/deploy.html}"

or, even better,

url = "http://www.nasa.gov/mission_pages/stereo/multimedia/deploy.html"

in your .bib file. You should also add to your main .tex file \usepackage{url} or \usepackage{hyperref} (bot not both!).
