   **What it does**

The tool generates a copy of the BAM input file with a modified header (i.e., metadata). 

It can update or replace read-group information (i.e., information about the samples in the file), add or replace comment lines, and rename reference sequences declared in the header.

The tool ensures that the resulting BAM file is valid and can be further processed by other MiModD tools and standard software like samtools. It aborts with an error message if a valid BAM file cannot be generated with the user-specified settings.
 
The template information used to modify or replace the input file metadata is provided through forms or, in the case of read-group information, can be taken from an existing SAM file as can be generated, for example, with the *NGS Run Annotation* tool.
