Read group information

Question

[misterie]

Hi,

I have aligned my files from many lines and I forgot to put information about a Read Group (RG). I know, that Picard MergeSamFiles is requiring that information in bam files. I have used a BWA software for alignment and I didn't use a -R option.

I have found a program called AddOrReplaceReadGroups from Picard package. Can I use it normally after alignemnt for adding information about RG?

Thank you in advance.
