Cell Annotations for TCR Cell Clonotypes
For TCR Cell Clonotypes, the Cell Annotations () element contains for each barcode the following categories (see figure 10.6):
- productive status;
- V, D, J and C segments;
- CDR3 length;
- the CDR3 amino acid sequence;
- the number of UMIs and reads supporting the clonotype (only for single chains).
Figure 10.6: View of Convert Clonotypes to Cell Annotations output from a TCR Cell Clonotypes, filtered to specific V segments and where the segments are shown for the primary clonotypes and the TRA + TRB, TRA and TRB chains. Not all barcodes have identified clonotypes for both TRA and TRB chains.
