preprocessing table output description

[singhd6]

i ran the follwoing command in mixcr for v gene usage analysis, my reads are without umi tag

i want to understand the preprocessing step

specifically the preprocessing step:
what does

<style> </style>

preprocessor

Filter [IGH] | Filter stops in CDR3, OOF in CDR3

my BCR sequencing data is IgH data, then why is there IgH filter <style> </style>

preprocessor

Filter [IGH] | Filter stops in CDR3, OOF in CDR3

If there are multiple chains in the data the analysis will be performed separately for each chain. IGH simply means that this is the number for all IGH clonotypes.
