What is tinselR?

tinselR (pronunced tinsel-er) at its’ most basic level is a graphical viewer of Newick-formatted phylogenetic trees and as an application for producing publication-ready figures. The power of tinselR comes with combining a genetic distance matrix for annotating a tree for epidemiological outbreak analyses. A genetic distance matrix contains SNP differences for all pairwise comparisons for the tips on the tree. One can also include a heatmap when that data is provided in the meta data file. When you are happy with the way the image looks, you can download as either a pdf, png, or tiff.

We have an open access publication for tinselR in Microbial Resouce Annocements.

Issues, problems, suggestions, thoughts

If you have any the above, please submit an issue on github.

Requires -

  • ggtree; see the quick start for how to install ggtree.
  • treeio; which will install with ggtree.
  • R version >= 3.6

Travis build status


Quick Start

1). Install devtools package

Run this code in your R console -

install.packages("devtools", dep=T)

2). Install ggtree and treeio

Note - installation of ggtree should automatically cause treeio to install

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

BiocManager::install("ggtree")

3). Install and launch the tinselR shiny application

Note - the released for production version should be installed by specifying the release branch (e.g. @release-V0.0.090)

devtools::install_github("jennahamlin/tinselR@release-V0.0.0.90")
library(tinselR)
run_app()

4). Load your data or use the example data

Please click on the ‘Data Upload’ pane, where you can upload your files.* Example data is available for playing with tinselR in the ‘Example Data’ pane of the application. The example data sets include all three files (tree, *gene, and meta) and are available for selection via one drop down menu

  • Phylogenetic Tree - required; a Newick generated tree

  • Genetic Distance data - optional for use with the annotation function; a tsv/txt/csv file - see below for image of genetic distance matrix.

  • Metadata - optional for easy correction of tip labels or adding a heatmap; a tsv/txt/csv file - requires column headers of Display.labels and Tip.labels. See image below for a csv file example.

Examples of both the genetic distance matrix and the metadata file

5). Alter or annotate your tree

Once the phylogenetic tree is uploaded you can -
  • Alter visualization parameters. See below for part of a tree with aligned tips.

Once the genetic distance file is uploaded you can -
  • add annotation to the visual representation of the tree. See below for a tree with annotated clade including the range of SNPs.

If column for heatmap is included in metadata file you can -
  • add the heatmap on to a tree with or without annotations. See below for a tree with annotated clades and a heatmap.

Known issues as October 23, 2020

  • If user uploads tree and genetic distance matrix and then annotates the tree, and then selects a meta data file, all previously placed annotations are wiped from the tree image.
