Functional annotation for segment files. The output formats are not well-defined and subject to change.

Category Variant Evaluation and Refinement

---

Overview

Perform functional annotation on a segment file (tsv). Outputs two files. The first is a tsv where each row is a segment and the annotations are the covered genes and which genes+exon is overlapped by the segment breakpoints. The second file has a gene for each row. The rest of the information is the segment on which it is covered. The first file will have the name as specified by the output parameter. The second will have '.gene_list.txt' appended. The functionality here is the same as seen in Oncotator with a SEG file as input, but with both SIMPLE_TSV and GENE_LIST as outputs.

Note that FuncotateSegments will support seg files from the GATK, whereas Oncotator will not.

FuncotateSegments can support hg38 seg files from the GATK.

FuncotateSegments does not support direct reading of cloud-based datasources.

For more information about Oncotator, on small variants, see Ramos AH, Lichtenstein L, et al. Oncotator: Cancer Variant Annotation Tool. Human Mutation (2015). http://dx.doi.org/10.1002/humu.22771

Usage example

   ./gatk FuncotateSegments \
    --data-sources-path dataSourcesFolder/ \
   --ref-version hg19 \
   --output-file-format SEG \
   -R reference.fasta \
   --segments input.seg \
   -O input.seg.funcotated.tsv \
   --transcript-list tx_list.txt

---

--exclude-intervals / -XL

One or more genomic intervals to exclude from processing
Use this argument to exclude certain parts of the genome from the analysis (like -L, but the opposite). This argument can be specified multiple times. You can use samtools-style intervals either explicitly on the command line (e.g. -XL 1 or -XL 1:100-200) or by loading in a file containing a list of intervals (e.g. -XL myFile.intervals).

--interval-exclusion-padding / -ixp

Amount of padding (in bp) to add to each interval you are excluding.
Use this to add padding to the intervals specified using -XL. For example, '-XL 1:100' with a padding value of 20 would turn into '-XL 1:80-120'. This is typically used to add padding around targets when analyzing exomes.

int  0  [ [ -∞  ∞ ] ]

---

--interval-merging-rule / -imr

Interval merging rule for abutting intervals
By default, the program merges abutting intervals (i.e. intervals that are directly side-by-side but do not actually overlap) into a single continuous interval. However you can change this behavior if you want them to be treated as separate intervals instead.

The --interval-merging-rule argument is an enumerated type (IntervalMergingRule), which can have one of the following values:

ALL

OVERLAPPING_ONLY

IntervalMergingRule  ALL

---

--interval-padding / -ip

Amount of padding (in bp) to add to each interval you are including.
Use this to add padding to the intervals specified using -L. For example, '-L 1:100' with a padding value of 20 would turn into '-L 1:80-120'. This is typically used to add padding around targets when analyzing exomes.

int  0  [ [ -∞  ∞ ] ]

---

--interval-set-rule / -isr

Set merging approach to use for combining interval inputs
By default, the program will take the UNION of all intervals specified using -L and/or -XL. However, you can change this setting for -L, for example if you want to take the INTERSECTION of the sets instead. E.g. to perform the analysis only on chromosome 1 exomes, you could specify -L exomes.intervals -L 1 --interval-set-rule INTERSECTION. However, it is not possible to modify the merging approach for intervals passed using -XL (they will always be merged using UNION). Note that if you specify both -L and -XL, the -XL interval set will be subtracted from the -L interval set.

The --interval-set-rule argument is an enumerated type (IntervalSetRule), which can have one of the following values:

UNION

Take the union of all intervals

INTERSECTION

Take the intersection of intervals (the subset that overlaps all intervals specified)

IntervalSetRule  UNION

---

--intervals / -L

One or more genomic intervals over which to operate

List[String]  []

---

List[String]  []

---

--read-validation-stringency / -VS

Validation stringency for all SAM/BAM/CRAM/SRA files read by this program. The default stringency value 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 --read-validation-stringency argument is an enumerated type (ValidationStringency), which can have one of the following values:

STRICT

LENIENT
