MeanQualityByCycle on Spark
Category Diagnostics and Quality Control
Overview
Program to generate a data table and chart of mean quality by cycle from a BAM file. Works best on a single lane/run of data, but can be applied to merged BAMs - the output may just be a little confusing. This is the Spark implementation of this tool.Additional Information
Read filters
This Read Filter is automatically applied to the data by the Engine before processing by MeanQualityByCycleSpark.
MeanQualityByCycleSpark 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 | |

0 | maximum number of bytes to read from a file into each partition of reads. Setting this higher will result in fewer partitions.

A file (with .pdf extension) to write the chart to.
File null

If true, create a BAM index when writing a coordinate-sorted BAM file.
boolean true
--create-output-bam-splitting-index
If true, create a BAM splitting index (SBI) when writing a coordinate-sorted BAM file.
boolean true
--create-output-variant-index / -OVI
If true, create a VCF index when writing a coordinate-sorted VCF file.
boolean true

Disable all tool default read filters (WARNING: many tools will not function correctly without their default read filters on)
boolean false
--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).
List[String] []
--gatk-config-file
A configuration file to use with the GATK.
String null
--gcs-max-retries / -gcs-retries
If the GCS bucket channel errors out, how many times it will attempt to re-initiate the connection
int 20 [ [ -∞ ∞ ] ]
--gcs-project-for-requester-pays
Project to bill when accessing "requester pays" buckets. If unset, these buckets cannot be accessed. User must have storage.buckets.get permission on the bucket being accessed.
String ""
--help / -h
display the help message
boolean false
--input / -I
BAM/SAM/CRAM file containing reads
List[GATKPath] []
--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] []
--num-reducers
For tools that shuffle data or write an output, sets the number of reducers. Defaults to 0, which gives one partition per 10MB of input.
int 0 [ [ -∞ ∞ ] ]
--output / -O
uri for the output file: a local file path
String null
--output-shard-tmp-dir
when writing a bam, in single sharded mode this directory to write the temporary intermediate output shards, if not specified .parts/ will be used
Exclusion: This argument cannot be used at the same time as sharded-output
.

boolean false
--program-name
Name of the program running
String null
--QUIET
Whether to suppress job-summary info on System.err.

List[GATKPath] []
--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
- SILENT
ValidationStringency SILENT
--reference / -R
Reference sequence
GATKPath null
--sharded-output
For tools that write an output, write the output in multiple pieces (shards)
