Hi, I want to replace the @RG info from one bam file (output.bam) by the @RG info from another (input.bam) creating a new.bam I tried it as follows:
samtools view -H input.bam | grep '@RG' > RG_header samtools addreplacerg -r RG_header -o new.bam output.bam
I get the following message:
[parse_args] The supplied RG line lacks an ID tag.
RG_header looks as follows:
@RG ID:CAUPUANXXnnn PU:170913_7001253F PL:ILLUMINA LB:55426 SM:55426
Thanks for your help.
