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 |
