# Instructions {.tabset .tabset-pills}

Welcome to the **metaseqR2** report! If you are familiar with the metaseqR 
report, then you will find that there are not many differences with respect to 
the presented information. Some diagnostic and exploration plots were added. The 
most notable difference is that __*all*__ plots are interactive. This helps a 
lot with exploration and interpretation but also adds a lot of computational
burden. However, relatively modern systems with recent browser versions should
be capable of rendering all the graphics. The metaseqR2 report has been tested 
with Google Chrome, Mozilla Firefox and Microsoft Edge. It has **not** been 
tested with Internet Explorer, Opera and Safari and most probably will not be. 
Other Chromium browsers (e.g. Brave) should also be fine.

One particular characteristic of the metaseqR2 report is that all plots are
interactive. This is achieved by using the standard graphics underlying data
with libraries including [Highcharts](https://www.highcharts.com/),
[Plotly](https://plot.ly/) and 
[jvenn](http://jvenn.toulouse.inra.fr/app/index.html) to create more 
user-friendly and directly explorable plots. Instructions on the usage of these 
plots follow:

* All plots are interactively **explorable**. This means that if you move your 
mouse **inside** the plot area (a move called *mouse-over*), you can retrieve 
information on each single data point. This applies to all plots. More 
specifically:
  + In **scatterplots**, if you mouse-over each point, information about this 
  point is presented, depending on the type of the plot. The data series from 
  which the point comes is also presented. For example, in a Volcano plot, fold 
  change and significance, as well as the name of the gene and the data category
  (e.g. up-regulated) will be presented.
  + In **barplots**, if you mouse-over each bar, information about this bar is 
  presented, such as the value it represents and the data series from which it
  comes. If the barplot contains groups of bars, then information about each 
  group is displayed. For example, in a Biodetection plot, each bar group
  presents the percentage of a biotype in the examined genome, the percentage
  in the sample and the detected percentage according to read counts.
  + In **boxplots**, if you mouse-over the boxes, the information about the 
  underlying distribution is displayed (maximum, upper quartile, median, lower
  quartile and minimum) as well as the data series. If you mouse-over an 
  outlier, then information on this single point is presented (e.g. value).
  + Some **barplots** have a **double** y-axis system corresponding to 
  **different** measurements or scales. For example in Biodetection barplots,
  the left y-axis presents abundant features while the right y-axis presents
  non-abundant features. In the Filtered barplot, y-axes present different 
  values (numbers and fractions).
  + **Line plots** can be moused-over too. Depending on the plot type, exact 
  values may or may not be shown, depending on how important it is to display 
  them, and to avoid over-crowding the plots. For example in Reads noise plot,
  we are interested in the trend and not so much in exact values.
  + **Heatmaps** can be moused-over too. Information on each heatmap cell will 
  be displayed.
* All scatterplots and heatmaps are **zoomable**. You need to press the left 
mouse button inside a plot area and draw a square area to zoom-in. If you wish 
to reset the zoom, there is a **button** appearing for this when zooming-in.
* Data series in scatterplots, barplots and boxplots can be **toggled** on or 
off by **clicking** on the **legend** name of each data series which is placed 
**below** each plot. For example, in Volcano plots, if you click on the name 
"Unregulated", then the respective data series will stop appearing in the plot. 
You can bring it **back** by clicking the legend again.
* All plots are **exportable**. On the **top right** corner of each scatterplot, 
barplot and boxplot, there is a menu button with several functionalities, 
including **exporting** in various formats and presenting the plot in 
**full-screen** mode. For heatmaps, this functionality is offered by a set of 
small buttons that appear if you mouse-over at the **top** of the heatmap.
* In Venn diagrams, if you **click** on the **number** for each category, the 
respective gene/transcript names will appear in the **box** on the right of the 
diagram.
* All plots can be **downloaded** in static formats (in formats according to 
```metaseqr2``` call) from the Results section.

The metaseqR2 report contains the sections described below, depending on which 
diagnostic and exploration plots have been asked for from the run command. As 
plots are categorized, if no plot from a specific category is asked for, then 
this category will not appear. Below, are the categories:

## Summary

The **Summary** section is further categorized in several subsections. 
Specifically:

* **Analysis summary:** This section contains an auto-generated text that 
analytically describes the computational process followed and summarized the
results of each step. This text can be used as is or with slight modifications
in the <u>Methods</u> section of an article.
* **Input options:** This section provides a list of the input arguments to the
pipeline in a more human-readable format.
* **Filtering:** This section reports in detail the number of filtered genes
decomposed according to the number of genes removed by each applied filter.
* **Differential expression:** This section reports in detail the number of
differentially expressed genes for each contrast, both when using only a p-value
cutoff as well as an FDR cutoff (numbers in parentheses), that is, genes passing
the multiple testing correction procedure selected. These numbers are also
calculated based on a simple fold change cutoff in log<sub>2</sub> scale. 
Finally, when multiple algorithms are used with p-value combination, this
section reports all the findings analytically per algorithm.
* **Command:** This section contains the command used to run the ```metaseqr2```
pipeline for users that want to experiment as well as a critical messages
displayed within the ```R``` session running ```metaseqr2``` displayed as a log.
Finally, if a targets file has been used to perform the analysis, a table
depicting the parameters in the targets files is created and a link to download
the actual targets file, but any relative paths to BAM files are stripped and
the user is responsible to prepend them if the targets file has to be reused in
another location, e.g. locally.
* **Tracks:** This section contains a link which opens a new window to the UCSC
Genome Browser where normalized tracks based on the input BAM files are 
displayed. If stranded tracks have been requested (according to the
sequencing protocol or technology), the a track hub is created to display the
stranded tracks. From this tab, you can also download bigWig files as well as 
copy track lines for manual input to the UCSC Genome Browser.

## Quality control 

The **Quality** control section contains several interactive plots concerning 
the overall quality control of each sample provided as well as overall 
assessments. The quality control plots are the *Multidimensional Scaling* 
(**MDS**) plot, the *Biotypes detection* (**Biodetection**) plot, the 
*Biotype abundance* (**Countsbio**) plot, the *Read saturation* (**Saturation**) 
plot, the *Read noise* (**ReadNoise**) plot, the *Correlation heatmap* 
(**Correlation**), the *Pairwise sample scatterplots* (**Pairwise**) and the 
*Filtered entities* (**Filtered**) plot. Each plot is accompanied by a detailed
description of what it depicts. Where multiple plot are available (e.g. one for
each sample), a selection list on the top of the respective  section allows the
selection of the sample to be displayed.

## Normalization

The **Normalization** section contains several interactive plots that can be 
used to inspect and assess the normalization procedure. Therefore, normalization
plots are usually paired, showing the same data instance normalized and not
normalized. The normalization plots are the *Expression boxplots* (**Boxplots**)
plots, the *GC content bias* (**GC bias**) plots, the *Gene length bias* 
(**Length bias**) plots, the *Within condition mean-difference*
(**Mean-Difference**) plots, the *Mean-variance relationship* 
(**Mean-Variance**) plot and the *RNA composition* (**Rna composition**) plot.
Each plot is accompanied by a detailed description of what it depicts. Where 
multiple plot are available (e.g. one for each sample), a selection list on the 
top of the respective section allows the selection of the sample to be 
displayed.

## Statistics

The **Statistics** section contains several interactive plots that can be used
to inspect and explore the outcome of statistical testing procedures. The 
statistics plots are the *Volcano plot* (**Volcano**), the 
*MA or Mean-Difference across conditions* (**MA**) plot, the 
*Expression heatmap* (**Heatmap**) plot, the 
*Chromosome and biotype distributions* (**Biodist**) plot, the
*Venn diagram across statistical tests* (**StatVenn**), the 
*Venn diagram across contrasts* (**FoldVenn**) and the *Deregulogram*. Each plot 
is accompanied by a detailed description of what it depicts. Please note that 
the heatmap plots only show the top percentage of differentially expressed genes 
as this is controlled by the ```reportTop``` parameter of the ```metaseqr2``` 
pipeline. When multiple plots are available (e.g. one for each contrast), a 
selection list on the top of the respective section allows the selection of the 
sample to be displayed.

## Results

The **Results** section contains a snapshot of differentially expressed genes in 
table format with basic information about each gene and links to external 
resources. Certain columns of the table are colored according to significance. 
Larger bars and more intense colors indicate higher significance. For example, 
the bar in the *p_value* column is larger if the genes has higher statistical 
significance and the fold change cell background is bright red if the gene is 
highly up-regulated. From the **Results** section, full gene lists can be 
downloaded in text tab-delimited format and viewed with a spreadsheet
application such as MS Excel. A selector on the top of the section above the 
table allows the display of different contrasts.

## References

The **References** section contains bibliographical references regading the
algorithms used by the ```metaseqr2``` pipeline and is adjusted according to the
algorithms selected.
