Checks: 6 1
Knit directory: NMD-analysis/
This reproducible R Markdown analysis was created with workflowr (version 1.7.0). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.
Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.
The command set.seed(20230314) was run prior to running
the code in the R Markdown file. Setting a seed ensures that any results
that rely on randomness, e.g. subsampling or permutations, are
reproducible.
Great job! Recording the operating system, R version, and package versions is critical for reproducibility.
Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.
Using absolute paths to the files within your workflowr project makes it difficult for you and others to run your code on a different machine. Change the absolute path(s) below to the suggested relative path(s) to make your code more reproducible.

Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.
The results in this page were generated with repository version e1af73f. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.
Note that you need to be careful to ensure that all relevant files for
the analysis have been committed to Git prior to generating the results
(you can use wflow_publish or
wflow_git_commit). workflowr only checks the R Markdown
file, but you know if there are other scripts or data files that it
depends on. Below is the status of the Git repository when the results
were generated:

Count data
Gene-level count data was retrieved from salmon files by
tximport into a DGEList object. During this process, genes
were removed if
- They were not considered as detectable (TPM < 0.5 in > 3 samples)
- They did not contain any annotation
These filtering steps returned gene-level counts for 10,957 genes.

Model description
In this analysis, we are interested in seeing how the knockdowns
behave differently to controls. Given the quality and clustering of the
data, we will perform five pairwise comparisons using limma
where all conditions (KD/OE) will be compared to controls.

Overall, we find that a total of 395 genes are differentially expressed between UPF3B KD and controls. 388 genes are differentially expressed between UPF3A KD vs Controls.

In order to do this, we will create a heatmap visualisaiton.
