**Inputs, outputs, and parameters**

Either a SAM file or a BAM file must be supplied. Galaxy automatically coordinate-sorts all uploaded BAM files.

**Read Groups are Important!**

Setting read groups correctly from the start will simplify your life greatly because you can merge multiple BAM files into one significantly reducing the number of analysis steps. Below we provide an explanation of read groups fields taken from GATK FAQ webpage:

.. csv-table::
   :header-rows: 1

    Tag,Importance,Definition,Meaning
    "ID","Required","Read group identifier. Each @RG line must have a unique ID. The value of ID is used in the RG tags of alignment records. Must be unique among all read groups in header section. Read group IDs may be modified when merging SAM files in order to handle collisions.","Ideally, this should be a globally unique identify across all sequencing data in the world, such as the Illumina flowcell + lane name and number.  Will be referenced by each read with the RG:Z field, allowing tools to determine the read group information associated with each read, including the sample from which the read came.  Also, a read group is effectively treated as a separate run of the NGS instrument in tools like base quality score recalibration (a GATK component) -- all reads within a read group are assumed to come from the same instrument run and to therefore share the same error model."
    "SM","Sample. Use pool name where a pool is being sequenced.","Required.  As important as ID.","The name of the sample sequenced in this read group.  GATK tools treat all read groups with the same SM value as containing sequencing data for the same sample.  Therefore it's critical that the SM field be correctly specified, especially when using multi-sample tools like the Unified Genotyper (a GATK component)."
    "PL","Platform/technology used to produce the read. Valid values: ILLUMINA, SOLID, LS454, HELICOS and PACBIO.","Important.  Not currently used in the GATK, but was in the past, and may return.  The only way to known the sequencing technology used to generate the sequencing data","It's a good idea to use this field."
    "LB","DNA preparation library identify","Essential for MarkDuplicates","MarkDuplicates uses the LB field to determine which read groups might contain molecular duplicates, in case the same DNA library was sequenced on multiple lanes."

**Example of Read Group usage**

Support we have a trio of samples: MOM, DAD, and KID.  Each has two DNA libraries prepared, one with 400 bp inserts and another with 200 bp inserts.  Each of these libraries is run on two lanes of an illumina hiseq, requiring 3 x 2 x 2 = 12 lanes of data.  When the data come off the sequencer, we would create 12 BAM files, with the following @RG fields in the header::

 Dad's data:
 @RG     ID:FLOWCELL1.LANE1      PL:illumina     LB:LIB-DAD-1 SM:DAD      PI:200
 @RG     ID:FLOWCELL1.LANE2      PL:illumina     LB:LIB-DAD-1 SM:DAD      PI:200
 @RG     ID:FLOWCELL1.LANE3      PL:illumina     LB:LIB-DAD-2 SM:DAD      PI:400
 @RG     ID:FLOWCELL1.LANE4      PL:illumina     LB:LIB-DAD-2 SM:DAD      PI:400

 Mom's data:
 @RG     ID:FLOWCELL1.LANE5      PL:illumina     LB:LIB-MOM-1 SM:MOM      PI:200
 @RG     ID:FLOWCELL1.LANE6      PL:illumina     LB:LIB-MOM-1 SM:MOM      PI:200
 @RG     ID:FLOWCELL1.LANE7      PL:illumina     LB:LIB-MOM-2 SM:MOM      PI:400
 @RG     ID:FLOWCELL1.LANE8      PL:illumina     LB:LIB-MOM-2 SM:MOM      PI:400

 Kid's data:
 @RG     ID:FLOWCELL2.LANE1      PL:illumina     LB:LIB-KID-1 SM:KID      PI:200
 @RG     ID:FLOWCELL2.LANE2      PL:illumina     LB:LIB-KID-1 SM:KID      PI:200
 @RG     ID:FLOWCELL2.LANE3      PL:illumina     LB:LIB-KID-2 SM:KID      PI:400
 @RG     ID:FLOWCELL2.LANE4      PL:illumina     LB:LIB-KID-2 SM:KID      PI:400

Note the hierarchical relationship between read groups (unique for each lane) to libraries (sequenced on two lanes) and samples (across four lanes, two lanes for each library).
