URL:
Example¶
This wrapper can be used in the following way:
rule merge_vcfs:
input:
vcfs=["snvs.chr1.vcf", "snvs.chr2.vcf"]
output:
"snvs.vcf"
log:
"logs/picard/mergevcfs.log"
params:
extra=""
# 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/mergevcfs"
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.
