Acts as a large memory buffer between processes that are connected with unix pipes for the case that one or more processes produces or consumes their input or output in bursts. By inserting a large memory buffer between such processes each process can run at full speed and the bursts can be smoothed out by the memory buffer.

Example

java -jar SamToFastq.jar \ F=my.fastq \ INTERLEAVE=true | java -jar FifoBuffer | bwa mem -t 8 \dev\stdin output.bam

Summary

Acts as a large memory buffer between processes that are connected with unix pipes for the case that one or more processes produces or consumes their input or output in bursts. By inserting a large memory buffer between such processes each process can run at full speed and the bursts can be smoothed out by the memory buffer.

Example

   java -jar SamToFastq.jar \

   java -jar FifoBuffer |
   bwa mem -t 8 -Y reference.fasta \dev\stdin output.bam
  

FifoBuffer (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
Optional Tool Arguments
--arguments_file		read one or more arguments files and add them to the command line
--BUFFER_SIZE	536870912	The size of the memory buffer in bytes.
--DEBUG_FREQUENCY	0	How frequently, in seconds, to report debugging statistics. Set to zero for never.
--help  -h	false	display the help message
--IO_SIZE	65536	The size, in bytes, to read/write atomically to the input and output streams.
--NAME		Name to use for Fifo in debugging statements.
--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.
--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	true	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

List[File]  []

---

--USE_JDK_DEFLATER / -use_jdk_deflater

WARNING

INFO

DEBUG

LogLevel  INFO

---

--version

display the version number for this tool

boolean  false
