Differences in the clone info between exportClones and exportAirr

[ShaowenJ]

Dear Mixcr developers,

Sorry for this naive question, but I realized the output from the exportAirr files, that in the "cdr3_aa" column the first letter was missing compared to "junction_aa" column.

Is that a reason for this?
Example:

Thanks,

Hi, in compliance with AIRR format description:

" Junction versus CDR3
We work with the IMGT definitions of the junction and CDR3 regions. Specifically, the IMGT JUNCTION includes the conserved cysteine and tryptophan/phenylalanine residues, while CDR3 excludes those two residues. Therefore, our junction and junction_aa fields which represent the extracted sequence include the two conserved residues, while the coordinate fields (cdr3_start and cdr3_end) exclude them."
