我正在尝试使用 baposter 模板构建海报，它工作正常，直到我添加了一些内联数学方程式和标签，然后我开始收到此错误，此外还有：“！\headerbox 的参数有一个多余的 }。”！段落在 \headerbox 完成之前结束。”，“！LaTeX 错误：这里没有可以结束的行。”对于我的“抽象”标题框。
任何关于如何解决这个问题的建议都将不胜感激，因为我在网上找不到任何东西。我不擅长使用乳胶，这是从模板中复制而来的，所以我不确定作者和标题之前的整个序言是否有必要。

在无法解决问题后，我删除了添加到 headerboxes 的标签，但这没有帮助。以防万一这与此有关，我在错误出现之前还添加了内联数学和 flushleft 环境，如下所示：
\headerbox{5. Results}{name=results,span=1,column=2,below=aims}{
\underline{Steady States}
\vspace{0.3em}
Tumour free - This steady state was unstable, ... 1 line of text
\vspace{0.3em}
Immune free - This steady state was unstable, ... 1 line text
Virus free - Stable steady states ... 1 line text
\includegraphics[width=6cm]{VF1}
\begin{flushleft}\label{eqns:steadystates}
$rd_{t}h_{e}(x^{*}_{u})^{3}$\\
$ + (rh_{e}(d_{e}+d_{t}h_{v}-d_{t}k) + rp_{e}x^{*}_{m})(x^{*}_{u})^{2}$\\
$+ (rh_{e}(d_{e}h_{v}-d_{t}h{v}k-d_{e}k) + kp_{e}(d_{u}-r)x^{*}_{m})x^{*}_{u}$\\
$- rkh_{e}d_{e}h_{v} = 0$
$x^{*}_{e} = \frac{p_{e}x^{*}_{m}\frac{x^{*}_{u}}{h_{v}+x^{*}_{u}}}{d_{e}+d_{t}x^{*}_{u}}$
\end{flushleft}
Tumour, virus, immune present - 1 line text
}
但是我在另一个 headerbox 中使用了相同的格式，所以不确定是否相关。抱歉发了这么长的帖子，只是想确保所有信息都在那里。谢谢！
答案1
baposter期望将徽标的定义应用于海报标题的左侧和右侧，即使eyecatcher传递给poster环境的键是false。在指定海报标题之前和指定作者姓名之后添加{}或{\includegraphics[width=2cm]{example-image-a}}，即可解决问题。作者姓名的规范也存在错误，可以通过替换\sf\vspace{0.2em}\\来纠正\sffamily\vspace{0.2em}。there is no line here to end如果您确实想将徽标添加到海报，这可以避免错误。最后，dvipsnames无法传递给baposter类。如果要使用这些名称，请\PassOptionsToPackage{dvipsnames}{xcolor}在声明 之前使用\documentclass。
您可以考虑切换至使用tcolorbox带有海报库的包，该包具有的所有功能baposter以及更多功能，并且受到包作者的支持。
