# Long LaTeX file causes a strange error [closed]

I have a long LaTeX article (1000 lines, single file) which also has a lot of figures and a few tables.

\documentclass[english]{egpubl}


The article compiles with a few warnings. However if I uncomment any of the lines in a paragraph near the end of file, I get an error:

! File ended while scanning use of \@writefile
Miktek 2.8 gave \end{document} as location
Miktek 2.9 gives \begin{document} as location


The error appears on 3rd build pass (not on the first 2 after cleaning project). The PDF file seems to be generated normally. However this error makes me nervous.

The offending paragraph:

To check segmentation expertize of the primary author,
%one dataset (F02) was manually segmented both by the primary author
and a neurosurgeon (the second author).
%Dice coefficient is 91\%, which is on par
%with segmentation correlations between neurosurgeons~\cite{ExpertDSCs} (86-96\% DSC).


I am using TeXnicCenter on Win7 x64 with 32-bit MiKTeX.

Should I just ignore this error, or is there a way to fix it?

What happens if you uncomment just this line: "one dataset (F02) was manually segmented both by the primary author"? –  Mario S. E. Apr 5 '13 at 15:31
Uncommenting any of those 3 lines leads to the error, including that one. –  Dženan Apr 5 '13 at 15:41
Have you read your .log file? I remember getting really strange errors on the second or third run once. I didn't understand them until I read through the entire .log file. It turned out I had to many figures and the error was actually "too many unprocessed floats" or something like that. You say you have a lot of those, so you might want to check. –  Anke Apr 5 '13 at 15:44
when i see errors like this (i don't think it's specific to miktex) it usually means there's a problem earlier in the file that's incidentally triggered by something happening later on. does the log say something like "\end occurred inside a group at level 1)"? if so, keep moving the \end{document}` back until this disappears, using the "divide and conquer" method to isolate the offending paragraph. comment that out, and try running the job through to the end; if the job then completes, you know where to look more closely. –  barbara beeton Apr 5 '13 at 15:50
