Best to post some kind of simple short file with the equation included.

Re: Very confused About the error "Misplaced alignment tab character"
I am facing the same problem. I am not following IEEE format but i have to
deal with same type of equation
\left\{\begin{matrix}
true &...& embed\\
false &...&skip \\
\end{matrix}\right.
i get 2 errors
1)$ missing
2) & misplaced alignment tab character

But you have Input amsdefs.inc in there which itself has Provides amsmath 1 This is because the ams classes, for which amsdefs.inc is written, load amsmath by themselves, and therefore LyX must not load it again. Writing Provides amsmath 0 somewhere _after_ the amsdefs inclusion in your layout file might fix the problem. HTH, Jürgen
Re: Very confused About the error "Misplaced alignment tab character"
Can't seem to find anything like that in the layout file. The layout was originally based on amsbook class, I modified it slightly to work with report class, perhaps that could have something to do with it. http://www.nabble.com/file/p17187814/unswthesis.layout unswthesis.layout -- View this message in context: http://www.nabble.com/Very-confused-About-the-error-%22Misplaced-alignment-tab-character%22-tp16918124p17187814.html Sent from the LyX - Users mailing list archive at Nabble.com.

This is strange. Do you have a modified *.layout file for the class that
happens to have
Provides amsmath 1
defined?

Thanks for the quick reply! In the process of making an example file... I
discovered that if I manually add \usepackage{amsmath} to the latex
preamble, it works. So for some reason my layout is ignoring the "use AMS
math" options.

Could you provide an example file? If I insert your example cases construct into the IEEEtran template, I get the error you describe (which actually shouldn't happen). However, if I switch on "use AMS math automatically" in Document->Settings->Math-Options), the document compiles without errors. Jürgen

Hi, I already had "Use AMS math package" checked, yet I still get the error. I'm using a layout which is based on report document class. Any ideas? I should just go with pure latex as I seem to be spending more time hunting for fixes like this than actually writing my thesis!

Thanks a lot for the hint, it seems that the problem happens not only to
IEEEtrans template but also to other Templates as well. Hope the coming
version will solve it.

Using the IEEETran template, you need to go to Document -> Settings...
-> Math Options and check either "Use AMS math package" or "Use AMS math
package automatically". For whatever reason, the "automatically" option
is on by default when you start a new document and set the class to
"article (IEEEtran)" but is off when you use the template. I'm not sure
if I'd call it a bug, but it might be a good idea for the developers to
switch AMS on in the template.
