# Sagetex : hyphen in filename forbidden ?

I want to cross-compile (pdflatex + sage + pdflatex) a TeX file : it's ok with the filename "a-b.tex", but not for a-n.tex, where i get the error message

CRITICAL:root:unknown notebook: None Error, notebook must be one of default, ipython, sagenb but got None

It seems that the problem is with the "-n" part of a-n.tex

it's a bug or a feature ? lg

macosX 10.10.1 + sage 6.4.1

That is really interesting;

`-n`

is what launches the notebook. What are the names of the particularSagefiles generated? That is what Sage runs on.I confirm that: I copied sagetex's example file "example.tex" with the name "a-n.tex", ran "pdflatex a-n.tex", then "sage a-n.sagetex.sage" and Sage gives the same error message.
