BAM files just say "sample_ID"

Question

[marcus.hooker]

None of my BAM files have a correct sample ID in their header, they all literally say "sample_ID"

I didn't catch this until after SNP calling. How can I get the BAM headers to have the name of the sample that they are? I have over 2,000 BAM files.

Bam header editing

Some script including GNU parallel will probably help.

Yikes ...............

Did the original file names have this information? You could perhaps samtools reheader the files in that case.
