You are an expert in bioinformatics, sequencing technologies, genomics data analysis, and adjacent fields.
You are given findings from a MultiQC report, generated by a bioinformatics workflow.
MultiQC supports various bioinformatics tools that output QC metrics, and aggregates those metrics
into a single report. It outputs a "General Statistics" table with key metrics for each sample across
all tools. That table is followed by more detailed sections from specific tools, that can include tables,
as well as plots of different types (bar plot, line plot, scatter plot, heatmap, etc.)
You are given data from such a report. Your task is to analyse the data, and
give 1-2 bullet points of a very short and concise overall summary for the results.
Don't waste words: mention only the important QC issues. If there are no issues, just say so.
Just print one or two bullet points, nothing else.
Please do not add any extra headers to the response.
Use markdown to format your reponse for readability. Use directives with pre-defined classes
.text-green, .text-red, and .text-yellow to highlight severity, e.g. :span[39.2%]{.text-red}.
Highlight any mentioned sample names or sample named prefixes or suffixes with a sample directive,
and make sure to use the same color classes for severity, e.g. :sample[A1001.2003]{.text-yellow}
or :sample[A1001]{.text-yellow}. Do not put multiple sample names inside one directive.
You must use only multiples of 4 spaces to indent nested lists.
Two examples of short summaries:
- :span[11/13 samples]{.text-green} show consistent metrics within expected ranges.
- :sample[A1001.2003]{.text-red} and :sample[A1001.2004]{.text-red} exhibit extremely high percentage of :span[duplicates]{.text-red} (:span[65.54%]{.text-red} and :span[83.14%]{.text-red}, respectively).
- All samples show good quality metrics with :span[75.7-77.0%]{.text-green} CpG methylation and :span[76.3-86.0%]{.text-green} alignment rates
- :sample[2wk]{.text-yellow} samples show slightly higher duplication (:span[11-15%]{.text-yellow}) compared to :sample[1wk]{.text-green} samples (:span[6-9%]{.text-green})'

Section: Sequence Counts
Section description: Sequence counts for each sample. Duplicate read counts are an estimate only.
Section help text: This plot show the total number of reads, broken down into unique and duplicate
if possible (only more recent versions of FastQC give duplicate info).
You can read more about duplicate calculation in the
FastQC documentation.
A small part has been copied here for convenience:
Only sequences which first appear in the first 100,000 sequences
in each file are analysed. This should be enough to get a good impression
for the duplication levels in the whole file. Each sequence is tracked to
the end of the file to give a representative count of the overall duplication level.The duplication detection requires an exact sequence match over the whole length of
the sequence. Any reads over 75bp in length are truncated to 50bp for this analysis.

Section: Sequence Quality Histograms
Section description: The mean quality value across each base position in the read.
Section help text: To enable multiple samples to be plotted on the same graph, only the mean quality
scores are plotted (unlike the box plots seen in FastQC reports).
Taken from the FastQC help:
The y-axis on the graph shows the quality scores. The higher the score, the better
the base call. The background of the graph divides the y axis into very good quality
calls (green), calls of reasonable quality (orange), and calls of poor quality (red).
The quality of calls on most platforms will degrade as the run progresses, so it is
common to see base calls falling into the orange area towards the end of a read.

The per sequence quality score report allows you to see if a subset of your
sequences have universally low quality values. It is often the case that a
subset of sequences will have universally poor quality, however these should

Section: Per Base Sequence Content
Section description: The proportion of each base position for which each of the four normal DNA bases has been called.
Section help text: To enable multiple samples to be shown in a single plot, the base composition data
is shown as a heatmap. The colours represent the balance between the four bases:
an even distribution should give an even muddy brown colour. Hover over the plot
to see the percentage of the four bases under the cursor.
To see the data as a line plot, as in the original FastQC graph, click on a sample track.
From the FastQC help:
Per Base Sequence Content plots out the proportion of each base position in a
file for which each of the four normal DNA bases has been called.In a random library you would expect that there would be little to no difference
between the different bases of a sequence run, so the lines in this plot should
run parallel with each other. The relative amount of each base should reflect
the overall amount of these bases in your genome, but in any case they should
not be hugely imbalanced from each other.It's worth noting that some types of library will always produce biased sequence
composition, normally at the start of the read. Libraries produced by priming
using random hexamers (including nearly all RNA-Seq libraries) and those which
were fragmented using transposases inherit an intrinsic bias in the positions
at which reads start. This bias does not concern an absolute sequence, but instead
provides enrichement of a number of different K-mers at the 5' end of the reads.
Whilst this is a true technical bias, it isn't something which can be corrected
by trimming and in most cases doesn't seem to adversely affect the downstream
analysis.

Section: Sequence Duplication Levels
Section description: The relative level of duplication found for every sequence.
Section help text: From the FastQC Help:
In a diverse library most sequences will occur only once in the final set.
A low level of duplication may indicate a very high level of coverage of the
target sequence, but a high level of duplication is more likely to indicate
some kind of enrichment bias (e.g. PCR over amplification). This graph shows
the degree of duplication for every sequence in a library: the relative
number of sequences with different degrees of duplication.Only sequences which first appear in the first 100,000 sequences
in each file are analysed. This should be enough to get a good impression
for the duplication levels in the whole file. Each sequence is tracked to
the end of the file to give a representative count of the overall duplication level.The duplication detection requires an exact sequence match over the whole length of
the sequence. Any reads over 75bp in length are truncated to 50bp for this analysis.In a properly diverse library most sequences should fall into the far left of the
plot in both the red and blue lines. A general level of enrichment, indicating broad
oversequencing in the library will tend to flatten the lines, lowering the low end
and generally raising other categories. More specific enrichments of subsets, or
the presence of low complexity contaminants will tend to produce spikes towards the
right of the plot.

Section: Overrepresented sequences by sample
Section description: The total amount of overrepresented sequences found in each library.
Section help text: FastQC calculates and lists overrepresented sequences in FastQ files. It would not be
possible to show this for all samples in a MultiQC report, so instead this plot shows
the number of sequences categorized as overrepresented.
Sometimes, a single sequence may account for a large number of reads in a dataset.
To show this, the bars are split into two: the first shows the overrepresented reads
that come from the single most common sequence. The second shows the total count
from all remaining overrepresented sequences.
From the FastQC Help:
A normal high-throughput library will contain a diverse set of sequences, with no
individual sequence making up a tiny fraction of the whole. Finding that a single
sequence is very overrepresented in the set either means that it is highly biologically
significant, or indicates that the library is contaminated, or not as diverse as you expected.FastQC lists all the sequences which make up more than 0.1% of the total.
To conserve memory only sequences which appear in the first 100,000 sequences are tracked
to the end of the file. It is therefore possible that a sequence which is overrepresented
but doesn't appear at the start of the file for some reason could be missed by this module.

Section help text: Note that only samples with ≥ 0.1% adapter contamination are shown.
There may be several lines per sample, as one is shown for each adapter
detected in the file.
From the FastQC Help:
The plot shows a cumulative percentage count of the proportion
of your library which has seen each of the adapter sequences at each position.
Once a sequence has been seen in a read it is counted as being present
right through to the end of the read so the percentages you see will only
increase as the read length goes on.

Tool: FastQC
Section: Status Checks
Section description: Status for each FastQC section showing whether results seem entirely normal (green),
slightly abnormal (orange) or very unusual (red).
Section help text: FastQC assigns a status for each section of the report.
These give a quick evaluation of whether the results of the analysis seem
entirely normal (green), slightly abnormal (orange) or very unusual (red).
It is important to stress that although the analysis results appear to give a pass/fail result,
these evaluations must be taken in the context of what you expect from your library.
A 'normal' sample as far as FastQC is concerned is random and diverse.
Some experiments may be expected to produce libraries which are biased in particular ways.
You should treat the summary evaluations therefore as pointers to where you should concentrate
your attention and understand why your library may not look random and diverse.
Specific guidance on how to interpret the output of each module can be found in the relevant
report section, or in the FastQC help.
In this heatmap, we summarise all of these into a single heatmap for a quick overview.
Note that not all FastQC sections have plots in MultiQC reports, but all status checks
are shown in this heatmap.
