If this is my file.tex:
Ras is capable of binding tightly to downstream effector molecules and
thereby propagate specific signaling pathways \cite{12581669}
and this my biblio.bib:
@article{12581669,
author = {Herrmann, C.},
title = {Ras-effector interactions: after one decade},
year = 2003,
journal = {Current opinion in structural biology},
volume = 13,
number = 1,
pages = {122--9},
pmid = 12581669,
keywords = {}
}
I get:
citation '12581669' on page 1 undefined.
and the numbering is "?"**
Some idea of what should I do?
bibtex? (And you're not actually using\usepackage{biblatex}as the tag suggests, are you?) – Torbjørn T. Jul 07 '15 at 15:55
