[Tex/LaTex] Argument of \mathaccentV has an extra }

amsmathmath-mode

I am not able to locate the source of this error.

! Argument of \mathaccentV has an extra }.
<inserted text>
\par
l.238
I've run across a `}' that doesn't seem to match anything.

Latex tells me that it is in line 238, but what I have in line 238 is the following text:

When we have a simulated cluster catalogue, we are given with
cosmological and spectroscopic redshifts. Distances

When there are no mathematical symbols or equations, how do I find out where the extra } is missing?

Why is Latex pointing in the wrong line?

EDIT:

I tried commenting section by section, but the error remained. Then I commented the entire file, but still when I compile, I get this error!! What is this sorcery? How can it throw an error when I have commented the entire document?

LOG FILE:

I have uploaded the .log file HERE, please can someone help me out??

The error appears in line 1703 of the .log file.

To locate the error look in the log for a ( without a matching ) before the error, In this case

(./Thesis.bbl

So the error is on line 238 of the generated bibliography

So, delete Thesis.bbl, fix the corresponding entry in the bib file and re-run latex and bibtex to re-generate.

As already suggested, you shouldn't reenvent the wheel ...

\documentclass{article}
\usepackage{mathtools}
\begin{document}

\begin{align*}
  \Aboxed{1 &= 2 }\\
  1 &\ne 2
\end{align*}

\end{document}

[Tex/LaTex] Argument of align has an extra ‘}’

The expression

 f(t) = ((x_t - x_{t-1})}

has one opening brace and two closing braces and that triggering the error message. The proper way to write the expression would be

f(t) = ((x_t - x_{t-1}) + (x_{t-1} - x_{t-2}))

or even better

f(t) = \bigl((x_t - x_{t-1}) + (x_{t-1} - x_{t-2})\bigr)

so the outer parentheses will be longer and this will increase readability.

On a side note, as egreg has mentioned, your code has also some other problems: the center environment is not necessary here and will add extra unwanted vertical space. For a single equation you should use equation instead of align. You shouldn't use two consecutive align environments; you can use a gather environment instead.

It's not clear why you want to split in that way a single formula; the breaking point that you've chosen and the numbering schema introduce ambiguity since the reader could get the impression that you are talking about two different expressions instead of two parts of a same formula. Perhaps you culd consider using \underbraces? Here are some options:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{gather}
    \label{avggrad}
    f(t) = \big((x_t - x_{t-1}) + (x_{t-1} - x_{t-2})\big) \times \frac{1}{2} \\ 
    \label{avggradsum}
  \frac{ \sum_{i=0}^{n-1} (x_{t-i}-x_{t-(i+1)}) }{n}
\end{gather}

\begin{equation}
    \label{avggrad}
    f(t) = \big((x_t - x_{t-1}) + (x_{t-1} - x_{t-2})\big) \times \frac{1}{2} \frac{ \sum_{i=0}^{n-1} (x_{t-i}-x_{t-(i+1)}) }{n}
\end{equation}

\begin{equation}
    \label{avggrad}
    f(t) = \underbrace{\big((x_t - x_{t-1}) + (x_{t-1} - x_{t-2})\big)}_{\text{some explanation}} \times \frac{1}{2} \underbrace{\frac{ \sum_{i=0}^{n-1} (x_{t-i}-x_{t-(i+1)}) }{n}}_{\text{some description}}
\end{equation}
