TCRcloud is a TCR repertoire visualization and comparison tool

TCRcloud is a TCR repertoire visualization and comparison tool

Instalation

TCRcloud is written in python and can be installed from PyPI using pip:

$ pip3 install TCRcloud

Currently it is only compatible with linux-64 and osx-64 because one of the dependencies used is also only compatible with those operating systems. It does work on WSL if you want to use Windows.

TCRcloud uses the AIRR Data Commons API and needs AIRR compliant data as input

Usage

To create a word cloud

$ TCRcloud cloud AIRR_rearrangements_file.tsv

By default TCRcloud colours the CDR3 based on the Vgene but you can provide a json file that atributes colours in Hex format to specific sequences:

{
"#FF0000":["CAASITGNQFYF","CAVREDGTSGSARQLTF"],
"#0000FF":["CAVMDSNYQLIW"]
}

The sequences not in the file will be coloured grey.

To use your custom colours for the word cloud

$ TCRcloud cloud AIRR_rearrangements_file.tsv -c colours.json

To create a word cloud without a legend

$ TCRcloud cloud AIRR_rearrangements_file.tsv -l False

To create a radar plot comparing diversity metrics

$ TCRcloud radar AIRR_rearrangements_file.tsv

By default TCRcloud uses repertoire_id but you can create a legend with the text you want by providing a json file:

{
"2839362682105696746-242ac113-0001-012":"Twin 2A",
"2939134772391776746-242ac113-0001-012":"Twin 2B"
}  

To create a radar plot with your desired legend

$ TCRcloud radar AIRR_rearrangements_file.tsv -c legend.json

To create a radar plot without a legend

$ TCRcloud radar AIRR_rearrangements_file.tsv -l False

Using TCRcloud you can download rearragements files from the AIRR compliant databases based on AIRR repertoire metadata files

To download AIRR rearrangements files

$ TCRcloud download AIRR_repertoire_file.json

TCRcloud provides some test data to experiment the tool. The data is one twin pair from the monozygotic twins study from the Mark Davis lab (DOI: 10.1038/ncomms11112)

To download the test data repertoire file

$ TCRcloud testdata

After having the testdata.airr.json file you can use the download function included in TCRcloud to get the matching rearragements file.

Examples:

TRA CDR3 word cloud

TRB CDR3 word cloud

TRG CDR3 word cloud

TRD CDR3 word cloud
