This tool sorts the input SAM or BAM file by coordinate, queryname (QNAME), or some other property of the SAM record. The SortOrder of a SAM/BAM file is found in the SAM file header tag @HD in the field labeled SO.

For a coordinate sorted SAM/BAM file, read alignments are sorted first by the reference sequence name (RNAME) field using the reference sequence dictionary (@SQ tag). Alignments within these subgroups are secondarily sorted using the left-most mapping position of the read (POS). Subsequent to this sorting scheme, alignments are listed arbitrarily.

For queryname-sorted alignments, all alignments are grouped using the queryname field but the alignments are not necessarily sorted within these groups. Reads having the same queryname are derived from the same template.

Usage example:

java -jar picard.jar SortSam \
      I=input.bam \
      O=sorted.bam \
      SORT_ORDER=coordinate

Overview

Sorts a SAM or BAM file.

Summary

This tool sorts the input SAM or BAM file by coordinate, queryname (QNAME), or some other property of the SAM record. The SortOrder of a SAM/BAM file is found in the SAM file header tag labeled SO.

For a coordinate sorted SAM/BAM file, read alignments are sorted first by the reference sequence name (RNAME) field using the reference sequence dictionary tag labeled SQ. Alignments within these subgroups are secondarily sorted using the left-most mapping position of the read (POS). Subsequent to this sorting scheme, alignments are listed arbitrarily.

For queryname-sorted alignments, all alignments are grouped using the queryname field but the alignments are not necessarily sorted within these groups. Reads having the same queryname are derived from the same template.

Inputs

• Input BAM or SAM file to sort
• Sorted BAM or SAM output file
• Sort order of output file

Usage example:

     java -jar picard.jar SortSam \
     INPUT=input.bam \
     OUTPUT=sorted.bam \
     SORT_ORDER=coordinate
 

SortSam (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 BAM or SAM file to sort.
--OUTPUT  -O	null	Sorted BAM or SAM output file.
--SORT_ORDER  -SO	null	Sort order of output file.
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
--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.
--REFERENCE_SEQUENCE  -R	null	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

Argument details

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.

display the help message

boolean  false

---

--INPUT / -I

Input BAM or SAM file to sort.

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

Sorted BAM or SAM output file.

R File  null

---

--QUIET / NA

Whether to suppress job-summary info on System.err.

Boolean  false

---

--REFERENCE_SEQUENCE / -R

Reference sequence file.

File  null

---

--showHidden / -showHidden
