Hi Julien, I took a look at the log file you enclosed. It took some work, because the thesis did not compile at first (missing images in the chapters were one of the problems). In general, try to provide a minimal working example when asking for help, not the entire document with all the bells and whistles.
The file now compiles on my laptop and the results, it seems to me, are what you wanted. I changed two things: (a) I switched from bibtex to biber as backend ( I could not get your thesis to work with bibtex, and in general biber works better with biblatex). (b) And I switched from refsection to refsegment in biblatex. Here is what you need to do: A. Switch from bibtex to biber. - be sure biber is installed on your system (it should. Try typing "biber" at a command prompt to verify. If not install it via MikTeX) - Change the bibtexall script (with an editor): in line 17 (the last line), replace "bibtex" with "biber" - Make sure bibtexall can be found by lyx (again try calling bibtexall from a command prompt, or ask for help from the Windows guys) - Check that in preferences>>Latex , i the section "Bibliography generation" you have selected "custom" and typed "bibtexall" (without quotes) in the following field - in Document>>Settings>>Bibliography>>Processor, select "biber" from the drop down menu - in your preamble, change the biblatex loading command to: \usepackage[backend=biber,style=nature]{biblatex} - finally, get rid of spaces in path names (this may be unnecessary) B. Switch from refsection to refsegment (see biblatex manual, section 3.10.3 for a discussion of how they differ) - in your chapters, replace the commands \begin{refsection} and \end{refsection} with, respectively, \begin{refsegment} and \end{refsegment} - at the end of your chapters, when you want the bibliography to appear, replace the simple \printbibliography command you have now with \printbibliography[segment=n] where "n" is "1" for your first bibliography (currently, your chapter 2), "n" = "2" for your second bibliography (currently your chapter 3), etcetera. Again, see the manual, sec 3.10.3 for a discussion I am sending the pdf output in a private message to avoid jamming the list servers.
