Welcome! PhyloCloud is an easy-to-use online platform for operating and interpreting phylogenetic trees and multiple sequence alignments, serving as a bridge between complex phylogenomic frameworks and non-expert users. Users can browse the public tree collections or build and save your own trees at your own workplace both registerially and anonymously
PhyloCloud provides entry point to annotated data and tools for phylogenomic research, regardless of whether registered or anonymous users. The home page of PhyloCloud indicates the most typical features so you can quickly start using PhyloCloud:
- Upload and visualize trees , registerially or anonymously
- Build your phylogenies by just one click
- Browse and search public tree collection
Besides of common usage for trees management, we also provide various phylogenetic tools to conduct various analysis
If you already have a tree, PhyloCloud implemented the state-of-art tree visualizing engine and provide various options for further modification or analysis.
- Tree visualization with further analysis
One of the core features in PhyloCloud is to allow user upload multiple trees as a collection. Click the Upload tree button at the top right corner of the page to open the upload panel.
Input trees are expected to be in plain text files which not bigger than 50MB(~500,000 tips), and at the moment we support Newick format and parse with ETE Toolkit, for further imformation about newick format, please check ETE Toolkit
Phylocloud also allows user to attach alignment (<500MB) with corresponding tree. If you upload alignment files alongside with treefiles, please note that they must share the same prefix, otherwise alignments are not able to detect as attachment.
Besides of data input, users can also choose if their collection private or public for other users. Collection name is optional, once a collection is created, it will generate a collection id and it will be the collection title if it was not named. Anonymous user will be directed to the collection page where storage the trees you just upload. For registered users, they will be redirected to my cloud where your private cloud is.
*Noted Anonymous users should remember the collection id otherwise it will be lost.
Phylocloud provides a automated phylogenetic workflows to construct phylogeneies with a simple click. Click here to explore more
Once the job has submit, it will be redirect to result page with job id. After a waiting patiently for a moment, result tree will be render and visualized on the result page.
*Noted users should remember the job id otherwise it will be lost.
In phylocloud we have storage a several of featured collections which is public and open for browsing and download. Click Featured Collection to enter the public collection portal. Once your interested collection, click the collection title and entered the collection page.
Here we show example of eggNOG5 collection:
- Trees of collection are displayed as tree cards with thumnails, with treecard you can find basic information of each tree, such as owner, title, and download button of tree and alignment(if there is)
- User can search trees by tree title or node's name against public collection or own collection. When users are at collection page, the search filter will switch to Current Collection where allows user to search within collection
Phylocloud provides a automated phylogenetic workflows to construct phylogeneies with a simple click. Submit nucleotide or amino acids sequences in FASTA format and infer a phylogeny using ETE-Toolkit predefined workflows. Click here to explore more
Once the job has submit, it will be redirect to result page with job id. After a waiting patiently for a moment, result tree will be render and visualized on the result page.
*Noted users should remember the job id otherwise it will be lost.
Phylocloud allows users to compute topological distances between trees and compare differences side-by-side.
Comparison result will be shown below, it consists of two part:
-
the first part is the topological comparisons, once you hover to the target node, it shows the features of the node and the corresponding note in the comparing target will be highlighted.
-
the second part is a statistic summary which contains the information of statistic difference. The reported values are:
- rf, Robinson-Foulds symmetric distance
- max_rf, maximum Robinson-Foulds value for this comparison
- norm_rf, Normalized Robinson-Foulds distance (RF/maxRF)
- eucl dist, Euclidean distance between two trees
- mismatches, number of mismatches that compare
- %src_br frequency of edges in target tree found in the reference (1.00 = 100% of branches are found)
- %ref_br frequency of edges in the reference tree found in target (1.00 = 100% of branches are found)
- effective_tree_size, Effective tree size used for comparisons (after pruning not shared items)
- treekoD Average distance among all possible subtrees in the original target trees to the reference tree
- subtrees Number of subtrees used for the comparison (applies only when duplicated items are use to decomposed target trees)
Phylocloud allows to download, parse and query a local copy of the NCBI/GTDB taxonomy database.
Query by Ids:
Taxa tree result will be shown below
Once upload your tree, you are able to visualize it on the TreePage
if you want to perform any analysis or annotations, such as taxonomic or evolutionary detection, click the Analyze from the navigator
if you want to perform any tree editing, such as node labeling, layouts editing, click the Control Panel on top left corner or right click to target node
if you want to perform any analysis or annotations, such as taxonomic or evolutionary detection, click the Analyze from the navigator
Currently we provide four options of analysis:
This action will extract taxa information from the tree leaves and annotated the tree accordingly.
By default, NCBI/GTDB TaxIDs will be extracted from the leaf names by splitting by the dot symbol (e.g, delimiter='.'), and taking the first element of the string (index=0), and choose NCBI or GTDB for Taxa DB.
NCBI annotation example https://phylocloud.cgmlab.org/tree_page/61c3061f33448902b5c2882b/
GTDB annotation example https://phylocloud.cgmlab.org/tree_page/6234703aa614694328db1570/
After select correctly column info, click Annotate
Taxa info will be activated in tree layouts at aligned panel
This action will scan tree topology and use species information of each leaf to infer speciation and duplication events.
By deafult, species names are extracted by splitting leaf names by the dot symbol (delimiter='.'), and taking the first element (index=0)
Check example https://phylocloud.cgmlab.org/tree_page/62458ebb0d85d1b583543600/
In this example case, delimiter is "_", so we need to replace "." with _ .
After annotation, Speciation events are lable as blue dots, and Duplication is red dots at the last comman ancestors
This action will link a multiple sequence alignment to the current tree.
check example tree https://phylocloud.cgmlab.org/tree_page/6245c056721288d60d0041ab/ with demo msa
After added alignment file, click Alignment layout on Control panel, alignment layout will be displayed
