Question 1

How do I reference my LaTeX tables or equations?

Accepted Answer

To reference a LaTeX table or equation in LaTeX you need to make sure that you insert a label in your table or equation.

For example, a simple LaTeX table may look like this:

\begin{table}
\begin{tabular}{ccccc}
  1 & 2 & 3 & 4 & 5 \
  6 & 7 & 8 & 9 & 10 \
\end{tabular}
\caption{\label{tab:somelabel} Caption}
\end{table}

Notice the \label{tab:somelabel} inside the \caption .

Similarly, a simple LaTeX equation may look like this:

\begin{equation}
\label{eqn:somelabel}
e=mc^2
\end{equation}

Notice the \label{eqn:somelabel}. Now, you can reference this table and equation from inside a LaTeX block using ef{tab:somelabel} and ef{eqn:somelabel}, respectively. Or, you can reference them from inside any other block by clicking on the reference button in the toolbar, ❡:

Question 2

Can I write a LaTeX equation over multiple lines? Using the multiline, aligned packages.

Accepted Answer

Sometimes a long equation needs to be broken over multiple lines, especially if using a double column export style.

For example, this equation would most likely span over two columns:

\begin{equation}
F = \{F_{x} \in  F_{c} : (|S| > |C|) \cap 
(minPixels  < |S| < maxPixels) \cap 
(|S_{conected}| > |S| - \epsilon) 
  \}
\end{equation}

To achieve correct break and alignment of the above equation try the code below. (Note: new lines (\) do not work in equation environments.)

\begin{equation}
\begin{aligned}
F ={} & \{F_{x} \in  F_{c} : (|S| > |C|) \
      & \cap (\mathrm{minPixels}  < |S| < \mathrm{maxPixels}) \
      & \cap (|S_{\mathrm{conected}}| > |S| - \epsilon)\}
\end{aligned}
\end{equation}

Authorea will utilize your author information to automatically fill out the submission fields required by the journal and will automatically compile your manuscript, figures, and supplemental data and directly send it to your journal of choice. Upon completion of the submission, you will receive an email confirmation with further instructions from the publisher, including how to make any changes you wish to make.

What journals can I submit to?

While Authorea is working to set up direct submissions with all major publisher, the following list shows which journals you can directly publish with today.

1. eLife

2. bioRxiv

3. SSRN

4. The American Geophysical Union:

• Earth and Space Science • Earth’s Future • Geochemistry, Geophysics, Geosystems • GeoHealth • Geophysical Research Letters • Global Biogeochemical Cycles • Journal of Advances in Modeling Earth Systems • Journal of Geophysical Research: – Atmospheres – Biogeosciences – Earth Surface – Oceans – Planets – Space Physics – Soli

Question 5

How to prevent wide or long tables from overflowing in the exported PDF

Accepted Answer

Basic tables

If your table is too wide and/or long and it does not easily fit on a Letter/A4 page, we suggest you customize the table look. Every table can be customized in its look: the number of rows and columns you want to export, as well as the font size. Just click on the table to see what options are available.

LaTeX tables

Is your table written in LaTeX? If so, keep reading for suggestions on how to fix horizontal and vertical flow.

Horizontal Overflow (Wide Tables)

A standard table in LaTeX is typically realized via the {tabular} environment. However, if the content is too wide to fit a single line of a printed page, the resulting PDF eventually looks broken as the content gets clipped at the edge of the page. You can see an example in Table 1 from this Authorea-generated PDF export.

To counteract this, one may use the more advanced {tabulary} package, a detailed introduction to which can be found here. The main difference in effect is that tabulary will re-wrap all column content so that it will fit the page, even if some content has to be pushed down some rows. The syntax is also slightly different (capita

Question 6

How to write in LaTeX

Accepted Answer

In order to insert blocks of LaTeX notation in your document, click on Insert from the toolbar menu and then click LaTeX. You can choose to set your default to LaTeX by changing your editor settings in your profile.

A new LaTeX block in your document is created where the cursor is. It looks like this:

LaTeX editing You can now type some LaTeX syntax. Hovering with your mouse on Preview, you will preview the rendered markdown content. Clicking outside of the block, you will render the content (a latex flag will be added next to the block for you). If your LaTeX contains any errors, we will let you know (an error flag will show next to Preview).

What type of LaTeX is supported? Authorea supports two engines for rendering LaTeX: LaTeXML and Pandoc. LaTeXML, the most powerful way to render LaTeX notation to the web, supports a large chunk of LaTeX packages and styles. This is an up to date list.

IMPORTANT: How to write LaTeX

DO NOT paste an entire LaTeX article in a LaTeX block! You can import a LaTeX document from your homepage if that is what you intend to do.
Only type LaTeX content in a LaTeX block, i.e. DO NOT include documentclass, preamble, frontmatter, macros or figures. In other words, only include what you would wri
