Hello! I am trying to conduct a SNP calling with HaplotypeCaller but i got an error message that theres something wrong with my *.BAM files. After checking what is wrong i got a message that my *BAM files do not have read groups. My question is how do i deal with that error? Can i add 'dummy read groups' so i could force running HaplotypeCaller? How the results would change if i would add read groups correctly? I dont quite understand the required parameters for AddOrReplaceReadGroups tool.
Here are headers of my *.BAM files (used: samtools viev -H ...):
P.S. I mapped whole human genome with 3 different tools. Raw NGS reads were pair-end reads.
Thanks in advance!
