When I compile my paper with Biber mode, I get the ERROR - "Cannot find control file 'springer.bcf'! - Did latex run successfully on your .tex file before you ran biber?" Also, If I compile it in pdfLaTeX mode, my references disappeared and question mark will be replaced in the text! what should I do?
Here is a part of my paper's text:
\documentclass[twocolumn]{svjour3}
\usepackage{blindtext}
\smartqed
\usepackage{graphicx}
\DeclareGraphicsExtensions{.pdf,.png}
\usepackage{wrapfig}
\usepackage{stfloats}
\usepackage{float}
\usepackage[ singlelinecheck=false % <-- important ]{caption}
\usepackage{latexsym}
\usepackage{amsmath}
\usepackage{multirow}
\usepackage{array}
\usepackage{mathtools,extarrows}
\usepackage{caption}
\begin{document}
...text...
\bibliographystyle{ieeetr}
\bibliography{MyCollection1}
\end{document}
biblatex(for which Biber would be the right backend), but standard BibTeX-bibliographies. In that case you need to run BibTeX and not Biber. But we can only be sure that this is the right solution if we get to see a full example document, please share an MWE/MWEB with us. – moewe Sep 22 '18 at 09:27
