Overview

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 |
The INPUT VCF or BCF file. | ||
--OUTPUT -O |
The output VCF or BCF. | ||
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 | |
--JAVASCRIPT_FILE -JS |
Filters a VCF file with a javascript expression interpreted by the java javascript engine. The script puts the following variables in the script context: 'variant' a VariantContext ( https://samtools.github.io/htsjdk/javadoc/htsjdk/htsjdk/variant/variantcontext/VariantContext.html ) and 'header' a VCFHeader ( https://samtools.github.io/htsjdk/javadoc/htsjdk/htsjdk/variant/vcf/VCFHeader.html ). Last value of the script should be a boolean to tell whether we should accept or reject the record. | ||
--MAX_FS |
1.7976931348623157E308 | The maximum phred scaled fisher strand value before a site will be filtered out. | |
--MIN_AB |
0.0 | The minimum allele balance acceptable before filtering a site. Allele balance is calculated for heterozygotes as the number of bases supporting the least-represented allele over the total number of base observations. Different heterozygote genotypes at the same locus are measured independently. The locus is filtered if any allele balance is below the limit. | |
--MIN_DP |
0 | The minimum sequencing depth supporting a genotype before the genotype will be filtered out. | |
--MIN_GQ |
0 | The minimum genotype quality that must be achieved for a sample otherwise the genotype will be filtered out. | |
--MIN_QD |
0.0 | The minimum QD value to accept or otherwise filter out the variant. | |
--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 |
true | 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 |
false | 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 |
