My document compiled normally, but it seems that there is an incompatibility between the packages etoc and pgfplots. The latex compiles, but not to recompile to get the references and the table of contents. I wrote this MWE. (the heatmap code is from Drawing heatmaps using TikZ)

How can I solve it?

pgfplotstableso everything around the table should not be needed. And the error will appear for one table line as well... (just giving some tips in order to reduce the code and to get an answer more quickly). – LaRiFaRi Aug 15 '14 at 06:13pgfplotstablepackage.etochas problems in the appendix. Remove the appendices and delete the.auxfile and it compiles. – percusse Aug 15 '14 at 08:35\etoctoccontentsline*command with a dummy sectioning unit nameappendixplaceholderwhich had not been declared toetoc. – Dec 20 '14 at 14:20
