We have corrected the identifier naming error in the fasta generated by clonal.tree.generation(). Previously, we used 'clonotype_index' to name identifiers, where each 'clonotype_index' represents a clonotype composed of the same IGHV gene, IGHJ gene and junction amino acid sequence. However, when constructing the clonal tree, we used the DNA sequence of the raw data, so the identifier should be named using 'sequence_id'.
