pandoc markdown_github with section-divs booboo

This compares the differences between pandoc's markdown and markdown_github engines when parsing <div> tags within sections.


In essence, if a <div> tag contains a header out of order with the main document, its contents will be appended to the div in the html document with markdown_github. If the following div appears after a level 3 header:

<div class='boo'>

## level 2

# test file
sample_chunk <- "
```{r hello, testing=as.logical(1), another=1 + 1}
x <- 1 + 1 # this evaluates to two
the value of x is `r x`"
file = "sample.Rmd"
writeLines(sample_chunk, con = file)

This utility will render the code and figures from a given package as a PDF
and place them into a directory called `<demo>-generated_files`. This requires
knitr, rmarkdown and LaTeX to be installed on your system.

Generating a bootstrap dendrogram with hierfstat's genet.dist

Generating a bootstrap dendrogram with hierfstat's genet.dist
Zhian N. Kamvar

This short tutorial is an answer to the question posed on the poppr forum:!msg/poppr/vEQ8vb2oObQ/RjTsndaCEQAJ

My ultimate goal when asking the previous question was to employ aboot in order to create a bootstraped dendrogram based on distances offered by the genet.dist function in hierfstat. That's why I was trying to create a tree based on Nei's distance this way - to verify that it worked! Unfortunately even after reading the aboot documentation, I still fail to understand how to do this. I would be grateful if someone could provide an example of using aboot in combination with genet.dist.

Find chromosome regions for given SSR GenBank IDs
#!/usr/bin/env python3
# This script will BLAST a series of GenBank IDs representing SSR sequences from
# Sirjusingh, C., Kohn, L.M., 2001. Characterization of microsatellites in the
# fungal plant pathogen, Sclerotinia sclerotiorum. Molecular Ecology 1, 267e269.
# This uses biopython to download the XML, save it to a file in the working
# directory, and then looks for matches that have Sclerotinia chromosome in the
# title and has a score of > 100. If there's a better way to do this, I would
# like to know it. Currently, it can download a few results at a time and then
