A tool for performing various IntervalList manipulations
Summary
This tool offers multiple interval list file manipulation capabilities, including: sorting, merging, subtracting, padding, and other set-theoretic operations. The default action is to merge and sort the intervals provided in the INPUTs. Other options, e.g. interval subtraction, are controlled by the arguments.Both IntervalList and VCF files are accepted as input. IntervalList should be denoted with the extension .interval_list, while a VCF must have one of .vcf, .vcf.gz, .bcf When VCF file is used as input, each variant is translated into an using its reference allele or the END INFO annotation (if present) to determine the extent of the interval. IntervalListTools can also "scatter" the resulting interval-list into many interval-files. This can be useful for creating multiple interval lists for scattering an analysis over.
Details
The IntervalList file format is designed to help the users avoid mixing references when supplying intervals and other genomic data to a single tool. A SAM style header must be present at the top of the file. After the header, the file then contains records, one per line in text format with the followingvalues tab-separated: - Sequence name (SN) - Start position (1-based) - End position (1-based, inclusive) - Strand (either + or -) - Interval name (ideally unique names for intervals) The coordinate system is 1-based, closed-ended so that the first base in a sequence has position 1, and both the start and the end positions are included in an interval. Example interval list file@HD VN:1.0 @SQ SN:chr1 LN:501 @SQ SN:chr2 LN:401 chr1 1 100 + starts at the first base of the contig and covers 100 bases chr2 100 100 + interval with exactly one base
Usage Examples
1. Combine the intervals from two interval lists:
java -jar picard.jar IntervalListTools \ ACTION=CONCAT \ I=input.interval_list \ I=input_2.interval_list \ O=new.interval_list
2. Combine the intervals from two interval lists, sorting the resulting in list and merging overlapping and abutting intervals:
java -jar picard.jar IntervalListTools \ ACTION=CONCAT \ SORT=true \ UNIQUE=true \ I=input.interval_list \ I=input_2.interval_list \ O=new.interval_list
3. Subtract the intervals in SECOND_INPUT from those in INPUT
java -jar picard.jar IntervalListTools \ ACTION=SUBTRACT \ I=input.interval_list \ SI=input_2.interval_list \ O=new.interval_list
4. Find bases that are in either input1.interval_list or input2.interval_list, and also in input3.interval_list:
java -jar picard.jar IntervalListTools \ ACTION=INTERSECT \ I=input1.interval_list \ I=input2.interval_list \ SI=input3.interval_list \ O=new.interval_list

Performs various IntervalList manipulations.Summary
This tool offers multiple interval list file manipulation capabilities, including: sorting, merging, subtracting, padding, and other set-theoretic operations. The default action is to merge and sort the intervals provided in the #INPUTs. Other options, e.g. interval subtraction, are controlled by the arguments.Both IntervalList and VCF files are accepted as input. IntervalList should be denoted with the extension htsjdk.samtools.util.IOUtil#INTERVAL_LIST_FILE_EXTENSION, while a VCF must have one of htsjdk.samtools.util.IOUtil#VCF_FILE_EXTENSION, htsjdk.samtools.util.IOUtil#COMPRESSED_VCF_FILE_EXTENSION, htsjdk.samtools.util.IOUtil#BCF_FILE_EXTENSION. When VCF file is used as input, each variant is translated into an using its reference allele or the END INFO annotation (if present) to determine the extent of the interval. IntervalListTools can also "scatter" the resulting interval-list into many interval-files. This can be useful for creating multiple interval lists for scattering an analysis over.

--SUBDIVISION_MODE / -M
Selects between various ways in which scattering of the interval-list can happen.
The --SUBDIVISION_MODE argument is an enumerated type (Mode), which can have one of the following values:
- INTERVAL_SUBDIVISION
- A simple scatter approach in which all output intervals have size equal to the total base count of the source list divided by the scatter count (except, possibly, in the last interval list).
- BALANCING_WITHOUT_INTERVAL_SUBDIVISION
- A scatter approach that differs from {@link Mode#INTERVAL_SUBDIVISION} in a few ways:
- No interval will be subdivided, and consequently, the requested {@link IntervalListTools#SCATTER_COUNT} is an upper bound of scatter count, not a guarante of the number of {@link IntervalList}s that will be produced (e.g., if scatterCount = 10 but there is only one interval in the input, only 1 interval list will be emitted).
- When an interval would otherwise be split, it is instead deferred to the next scatter list.
- The "target width" of each scatter list may be wider than what is computed for {@link Mode#INTERVAL_SUBDIVISION}.
Specifically, if the widest interval in the source interval list is larger than what would otherwise be the target width, that
interval's width is used.
This approach produces more consistently-sized interval lists, which is one of the objectives of scattering.
- BALANCING_WITHOUT_INTERVAL_SUBDIVISION_WITH_OVERFLOW
- A scatter approach that differs from {@link Mode#BALANCING_WITHOUT_INTERVAL_SUBDIVISION}. This approach tries to balance the number of bases in each interval list by estimating the remaining interval lists sizes. This is computed from the total number of unique bases and the bases we have consumed. This means that the interval list with the most number of unique bases is at most the ideal split length larger than the smallest interval list (unique number of bases).

Boolean false
--USE_JDK_INFLATER / -use_jdk_inflater
Use the JDK Inflater instead of the Intel Inflater for reading compressed input
Boolean false
--VALIDATION_STRINGENCY / NA
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.
The --VALIDATION_STRINGENCY argument is an enumerated type (ValidationStringency), which can have one of the following values:
- STRICT
- LENIENT
- SILENT
ValidationStringency STRICT
--VERBOSITY / NA
Control verbosity of logging.
