Compare two metrics files.This tool compares the metrics and histograms generated from metric tools to determine if the generated results are identical. Note that if there are differences in metric values, this tool describes those differences as the change of the second input metric relative to the first.
Usage example:
java -jar picard.jar CompareMetrics \
INPUT=metricfile1.txt \
INPUT=metricfile2.txt \
METRICS_TO_IGNORE=INSERT_LENGTH \
METRIC_ALLOWABLE_RELATIVE_CHANGE=HET_HOM_RATIO:0.0005 \
IGNORE_HISTOGRAM_DIFFERENCES=false

Overview
Compare two metrics files.CompareMetrics (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 | |
---|---|---|---|
Required Arguments | |||
--INPUT -I |
Metric files to compare. | ||
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 | |
--IGNORE_HISTOGRAM_DIFFERENCES -IHD |
false | Ignore any differences between the two metric file's histograms (useful if using the 'METRIC_ALLOWABLE_RELATIVE_CHANGE') | |
--METRIC_ALLOWABLE_RELATIVE_CHANGE -MARC |
Metric Allowable Relative Change. A colon separate pair of metric name and an absolute relative change. For any metric specified here, when the values are compared between the two files, the program will allow that much relative change between the two values. | ||
--METRICS_TO_IGNORE -MI |
Metrics to ignore. Any metrics specified here will be excluded from comparison by the tool. | ||
--OUTPUT -O |
Output file to write comparison results to. | ||
--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 |
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 |

List[File] []
--COMPRESSION_LEVEL

Whether to create an MD5 digest for any BAM or FASTQ files created.
boolean false
--GA4GH_CLIENT_SECRETS
Google Genomics API client_secrets.json file path.
String client_secrets.json
--help / -h
display the help message
boolean false
--IGNORE_HISTOGRAM_DIFFERENCES / -IHD
Ignore any differences between the two metric file's histograms (useful if using the 'METRIC_ALLOWABLE_RELATIVE_CHANGE')
boolean false
--INPUT / -I
Metric files to compare.
R List[File] []
--MAX_RECORDS_IN_RAM
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.
Integer 500000 [ [ -∞ ∞ ] ]
--METRIC_ALLOWABLE_RELATIVE_CHANGE / -MARC
Metric Allowable Relative Change. A colon separate pair of metric name and an absolute relative change. For any metric specified here, when the values are compared between the two files, the program will allow that much relative change between the two values.
List[String] []
--METRICS_TO_IGNORE / -MI
Metrics to ignore. Any metrics specified here will be excluded from comparison by the tool.
List[String] []
--OUTPUT / -O
Output file to write comparison results to.
File null
--QUIET
Whether to suppress job-summary info on System.err.
Boolean false
--REFERENCE_SEQUENCE / -R
Reference sequence file.
File null
--showHidden / -showHidden
display hidden arguments
boolean false
--TMP_DIR
One or more directories with space available to be used by this program for temporary storage of working files
List[File] []
--USE_JDK_DEFLATER / -use_jdk_deflater
Use the JDK Deflater instead of the Intel Deflater for writing compressed output
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
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
Control verbosity of logging.
The --VERBOSITY argument is an enumerated type (LogLevel), which can have one of the following values:
- ERROR
- WARNING
- INFO
- DEBUG
LogLevel INFO
--version
display the version number for this tool
boolean false
