The ggtree package should not be viewed solely as a standalone software. While it is useful for viewing, annotating and manipulating phylogenetic trees, it is also an infrastructure that enables evolutionary evidences that inferred by commonly used software packages in the field to be used in R.
These evolutionary evidences are not only used in annotating phylogenetic tree in ggtree but can also be further analyzed in R. Most of the tree viewer software including R packages focus on Newick and Nexus file formats, while there are file formats from different evolution analysis software that contain supporting evidences within the file that are ready for annotating a phylogenetic tree.
The ggtree package define several parser functions and S4 classes to store statistical evidences inferred by commonly used software packages.
It supports several file formats, including:. Correspondingly, ggtree defines several S4 classes to store evolutionary evidences inferred by these software packages, including:. In addition, ggtree also supports phylomultiPhylo defined by ape 10phylo4phylo4d defined by phylobase obkData defined in OutbreakTools and phyloseq defined in phyloseq.
In ggtreetree objects can be merged and evidences inferred from different phylogenetic analyses can be combined or compared and visualized. For each class, we defined get. A get. Related OTUs are not necessarily within a clade, they can be distantly related.
These methods are useful for clustering related OTUs or clades. The fortify method is used to convert tree object to a data. The output data. Detail descriptions of slots defined in each class are documented in class man pages. Users can use class? The get. With ggtreeevolutionary evidences inferred by commonly used software packages BEAST in this example can be easily transformed to a tidy data. The read. The only difference is the space in the sequences.
For example, if we set branch. We can also plot the dN or dS tree and others. We annotate the tree with information presented in rst and mlc file separately as demonstrated in previous sessions. All the features in both files are available for annotation. Supported File Formats Most of the tree viewer software including R packages focus on Newick and Nexus file formats, while there are file formats from different evolution analysis software that contain supporting evidences within the file that are ready for annotating a phylogenetic tree.
Parser functions The ggtree package implement several parser functions, including: read. S4 classes Correspondingly, ggtree defines several S4 classes to store evolutionary evidences inferred by these software packages, including: apeBootstrap for bootstrap analysis of ape::boot. Here is an overview of these S4 classes:. CODEML output: rst and mlc files We annotate the tree with information presented in rst and mlc file separately as demonstrated in previous sessions.

With ggtree, plotting trees in R has become really simple and I would encourage even R beginners to give it a try! The ggtree function directly plots a tree and support several layouts, such as rectangular, circular, slanted, cladogram, time-scaled, etc. You can visualize a time-scaled tree by specifying the parameter mrsd most recent sampling date. Guangchuang Yu and Tommy Tsan-Yuk Lam have written a great tutorial, highlighting some of the possibilities you can do within this package.

There are two branches, release and devel, in parallel. Release branch is more stable and only document improvement and bug fixes will commit to it. New functions will only commit to devel branch. Sometimes I may write blog post to introduce new functions which is not available in release branch, you need to install the devel version of ggtree in order to use these new functions.
If you got the could not find function error, upgrade your installation to latest release. If the error still exists after upgrading to latest release, you need to install the devel version. If you are new to R and want to use ggtree for tree visualization, please do learn some basic R and ggplot2. For users who want to use their own filesplease just use relative or absolute file path e. This is because the units are in two different spaces data and pixel.
Users can use xlim to allocate more space for tip label. For example, the tiplabels contains two parts, species name and accession number and we want to display species name in italicwe can use command like this:. The label can be provided by a data. User can use ggrepel package to repel overlapping text labels. For details, please refer to ggrepel usage examples.
If you want to only display a subset of bootstrap e. Another solution is converting the bootstrap value outside ggtree as I recommended in google group. Here is another exammple for multiple bootstrap support values.

As these variable is not available in your datasetyou will get the following error:. This can be fixed by using parameter inherit. This breaks containment, so that the plot no longer contains everything it needs, and causes problems if ggplot2 changes the order of the rows, as it does when facetting.

In the review they evaluate the root function in APE and the developers of APE have updated the software to correctly display support values when originally stored as node labels in version 3.
My question is, how do I re-root a tree using ggtree methods? Do I use the "ape" package root function to re-root a tree, then plot with ggtree? Currently, CRAN only has ape v3. Original tree, before any rerooting with support values :.
Re-rooted tree, with incorrect support labels:. I would appreciate any advice on how to re-root phylogenetic trees that show accurate support values after re-rooting using ggtree. FYI, According to the manuscript listed above, iTOL will correctly label the branchs with support values after re-rooting. A shorter version of my question: How can you re-root a tree after imported using the read. I think I have a partial solution. The recently updated R package ape ver 4.
This is a major improvement. This method would avoid using the read. However, there is still one problem. How can I root the tree to the midpoint?
I don't think that can be done using the ape root function, but I might be wrong?? The other common midpoint functions midpoint and midpoint.
I'm sorry, but I was wrong about the midpoint function in the phangorn R package. This function works great. By default, it uses the option node. Therefore, my workflow is the same as in my above comment.There are many software packages and webtools that are designed for displaying phylogenetic trees, such as TreeView PageFigTree 7TreeDyn Chevenet et al.
He et al. Only several of them, such as FigTreeTreeDyn and iTOLallow users to annotate the trees with coloring branches, highlighted clades and tree features. However, their pre-defined annotating functions are usually limited to some specific phylogenetic data.
As phylogenetic trees become more widely used in multidisciplinary studies, there is an increasing need to incorporate various types of the phylogenetic covariates and other associated data from different sources into the trees for visualizations and further analyses.
For instance, influenza virus has a wide host range, diverse and dynamic genotypes and characteristic transmission behaviors that are mostly associated with the virus evolution and essentially among themselves. Therefore, in addition to standalone applications that focus on each of the specific analysis and data type, researchers studying molecular evolution need a robust and programmable platform that allows the high levels integration and visualization of many of these different aspects of data raw or from other primary analyses over the phylogenetic trees to identify their associations and patterns.
To fill this gap, we developed ggtreea package for the R programming language R Core Team released under the Bioconductor project Gentleman et al. The ggtree is built to work with phylogenetic data object generated by treeioand display tree graphics with ggplot2 package Wickham that was based on the grammar of graphics Wilkinson et al. The R language is increasingly being used in phylogenetics. However, a comprehensive package, designed for viewing and annotating phylogenetic trees, particularly with complex data integration, is not yet available.
Most of the R packages in phylogenetics focus on specific statistical analyses rather than viewing and annotating the trees with more generalized phylogeny-associated data. Some packages, including ape Paradis, Claude, and Strimmer and phytools Revellwhich are capable of displaying and annotating trees, are developed using the base graphics system of R.
In particular, ape is one of the fundamental package for phylogenetic analysis and data processing. However, the base graphics system is relatively difficult to extend and limits the complexity of tree figure to be displayed. OutbreakTools Jombart et al. The ggplot2 system of graphics allows rapid customization and exploration of design solutions.
However these packages were designed for epidemiology and microbiome data respectively and did not aim to provide a general solution for tree visualization and annotation.
The ggtree package also inherits versatile properties of ggplot2and more importantly allows constructing complex tree figures by freely combining multiple layers of annotations using the tree associated data imported from different sources importation using treeio package is detailed in Chapter 2. The ggtree package is designed for annotating phylogenetic trees with their associated data of different types and from various sources.
These data could come from users or analysis programs, and might include evolutionary rates, ancestral sequences, etc. For instance, the data could be the geographic positions of the sampled avian influenza viruses informed by the survey locations and the ancestral nodes by phylogeographic inference in the viral gene tree Lam et al.
It is notable that ggplot2 itself does not provide low-level geometric objects or other support for tree-like structures, and hence ggtree is a useful extension on that regard.
Even though the other two phylogenetics-related R packages, OutbreakTools and phyloseqare developed based on ggplot2the most valuable part of ggplot2 syntax - adding layers of annotations - is not supported in these packages.
For example, if we have plotted a tree without taxa labels, OutbreakTools and phyloseq provide no easy way for general R users, who have little knowledge about the infrastructures of these packages, to add a layer of taxa labels. A full list of geometric layers provided by ggtree are summarized in Table 4.
The ggtree supports displaying phylogram and cladogram Figure 4.You seem to have the general approach right. Without looking at your data, I'll throw out a couple suggestions. This just needs the tree to annotate and the replicates. I don't know why this would screw things up.
If you attempt to visualize the tree with, say, FigTree, the program will complain if you provide the wrong one. It might be the case that your tree is actually annotated, but the program you are using to visualize it is screwing up. Are you getting both types of trees? I also like to do the all-in-one ML and bootstrapping approach, and this might make things easier if you feel comfortable doing so with your data.
Thank you very much for your answer. Yes, the existence of the alignment file in the -f b stage was the reason. I followed the manual more careful and finally I did it. I have two trees with the support values as you said, one can be opened with FigTree, the other with the braces for the nodes not. Now I'm facing a more serious problem, the values are quite low, but I believe that I have to make a new question for this. It's not the first time that you are helping me and I'm really grateful for that :.
