KeyError: 'RG'

[karen916]

Dear svtyper creative team： I have a little trouble using the software and would like to ask for your help. I always encounter the prompt that the RG field is missing in the bam file. Is there any way to solve it? (lumpy_env) [chenzhaojin@lfpara test1010]$ svtyper \

-B merge_1-10_1-30.bam \
-l my.bam.json
