This reproducible R Markdown analysis was created with workflowr (version 1.7.1). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
The R Markdown file has unstaged changes. To know which version of
the R Markdown file created these results, you’ll want to first commit
it to the Git repo. If you’re still working on the analysis, you can
ignore this warning. When you’re finished, you can run
wflow_publish to commit the R Markdown file and build the
HTML.
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(20221025) 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.
| absolute | relative |
|---|---|
| /Users/maevatecher/Documents/GitHub/locust-comparative-genomics/data | data |
| /Users/maevatecher/Documents/GitHub/locust-comparative-genomics/data/orthofinder/Schistocerca | data/orthofinder/Schistocerca |
| /Users/maevatecher/Documents/GitHub/locust-comparative-genomics/data/orthofinder/Polyneoptera/Results_I2_iqtree/ | data/orthofinder/Polyneoptera/Results_I2_iqtree |
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 510c1f0. 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:

species_order <- c( "nitens", "cubense", "americana", "piceifrons", "cancellata", "gregaria")Here our objective is to compare the abundance, composition and
overlap of the DEGs found in the head and thorax tissues of each species
between the isolated and crowded last instar females. We found that the
differential genes expressed detected by DESeq2 varied
across species and tissues but we need some perspective: Are locusts
up-regulated and down-regulated the same genes? In the later section GO
enrichment, we will investigate what are the functions of these genes as
we will see that each species seems to show different gene expression
profiles in response to density changes.
STRATEGY 1: One genome S. gregaria
1. DEGs comparison among species
We summarized the number of genes differential expressed between density for each species and each tissues.

STRATEGY 2: Own RefSeq genome
Here the difference with STRATEGY 1 is that to look at the correspondance of genes across species for comparison, we will have to use orthologs (see section Orthofinder).
We load from our previous conversion
# Path for all species
ortho_dir <- "/Users/maevatecher/Documents/GitHub/locust-comparative-genomics/data/orthofinder/Polyneoptera/Results_I2_iqtree/"
input_file <- file.path(ortho_dir, "Orthogroups_genesproteinbiotype_13species_annotated_May2025.csv")
filtered_final_orthotable <- read.csv(input_file, header = TRUE, stringsAsFactors = FALSE)1. DEGs comparison among species
We summarized the number of genes differential expressed between density for each species and each tissues.
