Collect metrics to assess oxidative artifacts.This tool collects metrics quantifying the error rate resulting from oxidative artifacts. For a brief primer on oxidative artifacts, see the GATK Dictionary.
This tool calculates the Phred-scaled probability that an alternate base call results from an oxidation artifact. This probability score is based on base context, sequencing read orientation, and the characteristic low allelic frequency. Please see the following reference for an in-depth discussion of the OxoG error rate.
Lower probability values implicate artifacts resulting from 8-oxoguanine, while higher probability values suggest that an alternate base call is due to either some other type of artifact or is a real variant.
Usage example:
java -jar picard.jar CollectOxoGMetrics \
I=input.bam \
O=oxoG_metrics.txt \
R=reference_sequence.fasta

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 | |

[] | read one or more arguments files and add them to the command line | |
--CONTEXT_SIZE |
1 | The number of context bases to include on each side of the assayed G/C base. | |
--CONTEXTS |
[] | The optional set of sequence contexts to restrict analysis to. If not supplied all contexts are analyzed. | |

null | VCF format dbSNP file, used to exclude regions around known polymorphisms from analysis. | |
--help -h |
false | display the help message | |
--INCLUDE_NON_PF_READS -NON_PF |
true | Whether or not to include non-PF reads. | |
--INTERVALS |
null | An optional list of intervals to restrict analysis to. | |
--MAXIMUM_INSERT_SIZE -MAX_INS |
600 | The maximum insert size for a read to be included in analysis. Set of 0 to allow unpaired reads. | |

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. | |

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. | |

--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 |
