TCRcloud 1.0.0

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

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

Usage

To create a wordcloud

$ TCRcloud cloud -a 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 -a AIRR_rearrangements_file.tsv -c colours.json

To create a radar plot comparing diversity metrics

$ TCRcloud radar -a 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 -a AIRR_rearrangements_file.tsv -l legend.json

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 -a 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
