Creates ClusTCR matrix This function identifies similar CDR3 amino acid sequences based on the same length and V_gene
ClusTCR_Large(my_file, allele = NULL, v_gene = "v_call")X by Y matrix of structurally related CDR3 sequences.
uploaded file with junction_aa (CD3 sequences), variable gene.
The allele, if present as *00 will be removed if the user requires it.
