I'm trying to import this latex document into Lyx (version 2.0.2 on Ubuntu 12.04), but it fails and won't give any explanation about the error:

Lyx: cannot convert file
 An error occurred while running: tex2lyx -f "frontespizio.tex" "frontespizio.lyx" 

What could be the problem here?

  • This works under LyX 2.0.4 (with some minor editing, of course). Perhaps consider updating? Once that's done, give some more feedback. – Werner Sep 16 '12 at 13:56
  • Does importing fail, or compiling? I was able to import [File --> Import --> LaTeX (plain)] without errors, but it gave an error on compiling, but the PDF was still generated. Ubuntu 12.04, LyX 2.0.2. – Torbjørn T. Sep 16 '12 at 14:00
  • I can't import it at all. Here's the output: Lyx: cannot convert file An error occurred while running: tex2lyx -f "frontespizio.tex" "frontespizio.lyx" I will update the question with this piece of information. – Ricky Robinson Sep 16 '12 at 14:15
  • I updated to Lyx 2.0.4, but got the same error. – Ricky Robinson Sep 17 '12 at 9:14

Too long for a comment:

Importing the downloaded file into a non-UTF8 editor (like TeXnicCenter 1.0), reveals:

The first character could be the cause of the problem - called a Byte Order Mark. Even importing this into LyX 2.0.4 adds the following into the preamble (Document > Settings > LaTeX Preamble):

which you'll have to remove. Either remove this from the file first before importing, or attempt an update of your version from 2.0.2 to 2.0.4 and remove it after importing.

  • Thank you. Is there any ordinary text editor that I can use to remove that first character? I can't seem to find it. I also wanted to upgrade to Lyx 2.0.4, but www.lyx.org isn't responding. – Ricky Robinson Sep 16 '12 at 22:13

    Here is a BOM-free version of frontespizio.tex on Pastebin. Copy and paste this in a regular (UTF8-free) file/editor and (re)try importing it in LyX. – Werner Sep 17 '12 at 0:02
  • Thanks. I copied and pasted into gedit, but it didn't work. Same thing when I saved the file directly from pastebin. Updating to 2.0.4 also didn't work. I don't know how to proceed at this point. – Ricky Robinson Sep 17 '12 at 9:15

    @RickyRobinson: Are you still getting the same error when importing using LyX 2.0.4? Here's the LyX 2.0.4 file of frontespizio.tex. After importing I erased the BOM, as well as the two comments around some title. – Werner Sep 17 '12 at 13:54
  • I was getting the same error, yes. But thank you so much for the .lyx file! This time of course it worked. :) – Ricky Robinson Sep 17 '12 at 14:30

I did the importation when I open the tex file with Kile, after that opening it with TexnicCenter and finally the Lyx (2.1) in Windows.

  • That is very particular (what if I don't have Kile, say) and convoluted... it's most likely just because one of these applications strips unidentifiable characters... – Werner Jun 27 '14 at 21:01

If you change the document class from svjour3 to revtex and the converter works well! If you still need to work in a svjour3 or report class, reconstruct an empty LyX file from the template and copy all things you obtained from the revtex class and this may solve the problem.
