Assigns all the reads in a file to a single new read-group. This tool accepts INPUT BAM and SAM files or URLs from the Global Alliance for Genomics and Health (GA4GH).
Usage example:
java -jar picard.jar AddOrReplaceReadGroups \ I=input.bam \ O=output.bam \ RGID=4 \ RGLB=lib1 \ RGPL=ILLUMINA \ RGPU=unit1 \ RGSM=20Caveats
The value of the tags must adhere (according to the SAM-spec) with the regex'^[ -~]+$'
(one or more characters from the ASCII range 32 through 126). In particular <Space> is the only non-printing character allowed.
The program enables only the wholesale assignment of all the reads in the INPUT to a single read-group. If your file already has reads assigned to multiple read-groups, the original RG value will be lost.
For more information about read-groups, see the GATK Dictionary entry.

Overview
Assigns all the reads in a file to a single new read-group.Summary
Many tools (Picard and GATK for example) require or assume the presence of at least oneRG
tag, defining a "read-group"
to which each read can be assigned (as specified in the RG
tag in the SAM record).
This tool enables the user to assign all the reads in the {@link #INPUT} to a single new read-group.
For more information about read-groups, see the
GATK Dictionary entry.
This tool accepts as INPUT BAM and SAM files or URLs from the Global Alliance for Genomics and Health (GA4GH).
Usage example:
java -jar picard.jar AddOrReplaceReadGroups \ I=input.bam \ O=output.bam \ RGID=4 \ RGLB=lib1 \ RGPL=ILLUMINA \ RGPU=unit1 \ RGSM=20
Caveats
The value of the tags must adhere (according to the SAM-spec) with the regex{@value #READGROUP_ID_REGEX}(one or more characters from the ASCII range 32 through 126). In particular
<Space>
is the only non-printing character allowed.
The program enables only the wholesale assignment of all the reads in the {@link #INPUT} to a single read-group. If your file already has reads assigned to multiple read-groups, the original
RG
value will be lost.

AddOrReplaceReadGroups (Picard) specific arguments
This table summarizes the command-line arguments that are specific to this tool. For more details on each argument, see the list further down below the table or click on an argument name to jump directly to that entry in the list.
Argument name(s) | Default value | Summary | |
---|---|---|---|
Required Arguments | |||
--INPUT -I |
Input file (BAM or SAM or a GA4GH url). | ||
--OUTPUT -O |
Output file (SAM, BAM or CRAM). | ||
--RGLB -LB |
Read-Group library | ||
--RGPL -PL |
Read-Group platform (e.g. ILLUMINA, SOLID) | ||
--RGPU -PU |
Read-Group platform unit (eg. run barcode) | ||
--RGSM -SM |
Read-Group sample name | ||
Optional Tool Arguments | |||
--arguments_file |
read one or more arguments files and add them to the command line | ||
--help -h |
false | display the help message | |
--RGCN -CN |
Read-Group sequencing center name | ||
--RGDS -DS |
Read-Group description | ||
--RGDT -DT |
Read-Group run date | ||
--RGFO -FO |
Read-Group flow order | ||
--RGID -ID |
1 | Read-Group ID | |
--RGKS -KS |
Read-Group key sequence | ||
--RGPG -PG |
Read-Group program group | ||
--RGPI -PI |
Read-Group predicted insert size | ||
--RGPM -PM |
Read-Group platform model | ||
--SORT_ORDER -SO |
Optional sort order to output in. If not supplied OUTPUT is in the same order as INPUT. | ||
--version |
false | display the version number for this tool | |
Optional Common Arguments | |||
--COMPRESSION_LEVEL |
5 | Compression level for all compressed files created (e.g. BAM and VCF). | |
--CREATE_INDEX |
false | Whether to create an index when writing VCF or coordinate sorted BAM output. | |
--CREATE_MD5_FILE |
false | Whether to create an MD5 digest for any BAM or FASTQ files created. | |
--MAX_RECORDS_IN_RAM |
500000 | When writing files that need to be sorted, this will specify the number of records stored in RAM before spilling to disk. Increasing this number reduces the number of file handles needed to sort the file, and increases the amount of RAM needed. | |
--QUIET |
false | Whether to suppress job-summary info on System.err. | |
--REFERENCE_SEQUENCE -R |
Reference sequence file. | ||
--TMP_DIR |
One or more directories with space available to be used by this program for temporary storage of working files | ||
--USE_JDK_DEFLATER -use_jdk_deflater |
false | Use the JDK Deflater instead of the Intel Deflater for writing compressed output | |
--USE_JDK_INFLATER -use_jdk_inflater |
false | Use the JDK Inflater instead of the Intel Inflater for reading compressed input | |
--VALIDATION_STRINGENCY |
STRICT | Validation stringency for all SAM files read by this program. Setting stringency to SILENT can improve performance when processing a BAM file in which variable-length data (read, qualities, tags) do not otherwise need to be decoded. | |
--VERBOSITY |
INFO | Control verbosity of logging. | |
Advanced Arguments | |||
--showHidden |
false | display hidden arguments |
