Not to be confused with SortSam which sorts a SAM or BAM file with a valid sequence dictionary, ReorderSam reorders reads in a SAM/BAM file to match the contig ordering in a provided reference file, as determined by exact name matching of contigs. Reads mapped to contigs absent in the new reference are dropped. Runs substantially faster if the input is an indexed BAM file. Example java -jar picard.jar ReorderSam \ INPUT=sample.bam \ OUTPUT=reordered.bam \ REFERENCE=reference_with_different_order.fasta

Overview
Reorders a SAM/BAM input file according to the order of contigs in a second reference file.Summary

ReorderSam (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 |
null | Input file (SAM or BAM) to extract reads from. | |
--OUTPUT -O |
null | Output file (SAM or BAM) to write extracted reads to. | |
--REFERENCE -R |
null | Reference sequence to reorder reads to match. A sequence dictionary corresponding to the reference fasta is required. Create one with CreateSequenceDictionary. | |
Optional Tool Arguments | |||
--ALLOW_CONTIG_LENGTH_DISCORDANCE -U |
false | If true, then permits mapping from a read contig to a new reference contig with the same name but a different length. Highly dangerous, only use if you know what you are doing. | |
--ALLOW_INCOMPLETE_DICT_CONCORDANCE -S |
false | If true, then allows only a partial overlap of the original contigs with the new reference sequence contigs. By default, this tool requires a corresponding contig in the new reference for each read contig | |
--arguments_file |
[] | read one or more arguments files and add them to the command line | |
--help -h |
false | display the help message | |
--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 a BAM index when writing a coordinate-sorted BAM file. | |
--CREATE_MD5_FILE |
false | Whether to create an MD5 digest for any BAM or FASTQ files created. | |
--GA4GH_CLIENT_SECRETS |
client_secrets.json | Google Genomics API client_secrets.json file path. | |
--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. | |
--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 |

Arguments in this list are specific to this tool. Keep in mind that other arguments are available that are shared with other tools (e.g. command-line GATK arguments); see Inherited arguments above.
--ALLOW_CONTIG_LENGTH_DISCORDANCE / -U
If true, then permits mapping from a read contig to a new reference contig with the same name but a different length. Highly dangerous, only use if you know what you are doing.
boolean false

If true, then allows only a partial overlap of the original contigs with the new reference sequence contigs. By default, this tool requires a corresponding contig in the new reference for each read contig
boolean false
--arguments_file / NA
read one or more arguments files and add them to the command line
List[File] []
--COMPRESSION_LEVEL / NA
Compression level for all compressed files created (e.g. BAM and VCF).
int 5 [ [ -∞ ∞ ] ]
--CREATE_INDEX / NA
Whether to create a BAM index when writing a coordinate-sorted BAM file.
Boolean false
--CREATE_MD5_FILE / NA
Whether to create an MD5 digest for any BAM or FASTQ files created.
boolean false
--GA4GH_CLIENT_SECRETS / NA
Google Genomics API client_secrets.json file path.
String client_secrets.json
--help / -h
display the help message
boolean false
--INPUT / -I
Input file (SAM or BAM) to extract reads from.
R File null
--MAX_RECORDS_IN_RAM / NA
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.
Integer 500000 [ [ -∞ ∞ ] ]
--OUTPUT / -O
Output file (SAM or BAM) to write extracted reads to.
R File null
--QUIET / NA
Whether to suppress job-summary info on System.err.
Boolean false

R File null
--showHidden / -showHidden
display hidden arguments
boolean false
--TMP_DIR / NA

List[File] []
--USE_JDK_DEFLATER / -use_jdk_deflater
