Selection Methods

Search the database in the following methods:

Database search: Search the database by features such as organism, TCR germline.
CDR search: Search the database based on sequences of the TCR's CDR loops (IMGT definition).
Orientation search: Explore the relative orientations of the Vα/Vβ domains.
Sequence search: Search for a TCR template structure by submitting a sequence.
