Example¶
This wrapper can be used in the following way:
rule sort_bam:
input:
"mapped/{sample}.bam"
output:
"sorted/{sample}.bam"
log:
"logs/picard/sort_sam/{sample}.log"
params:
sort_order="coordinate",
extra="VALIDATION_STRINGENCY=LENIENT" # optional: Extra arguments for picard.
# optional specification of memory usage of the JVM that snakemake will respect with global
# resource restrictions (https://snakemake.readthedocs.io/en/latest/snakefiles/rules.html#resources)
# and which can be used to request RAM during cluster job submission as `{resources.mem_mb}`:
# https://snakemake.readthedocs.io/en/latest/executing/cluster.html#job-properties
resources:
mem_mb=1024
wrapper:
"0.85.0/bio/picard/sortsam"
Note that input, output and log file paths can be chosen freely.
When running with
snakemake --use-conda
the software dependencies will be automatically deployed into an isolated environment before execution.
