PRESEQ LC_EXTRAP¶
preseq
estimates the library complexity of existing sequencing data to then estimate the yield of future experiments based on their design. For usage information, please see preseq
’s command line help (this seems more up to date than the available documentation from 2014 ). For more information about preseq
, also see the source code.
Software dependencies¶
- preseq ==2.0.3
Example¶
This wrapper can be used in the following way:
rule preseq_lc_extrap_bam:
input:
"samples/{sample}.sorted.bam"
output:
"test_bam/{sample}.lc_extrap"
params:
"-v" #optional parameters
log:
"logs/test_bam/{sample}.log"
wrapper:
"0.67.0/bio/preseq/lc_extrap"
rule preseq_lc_extrap_bed:
input:
"samples/{sample}.sorted.bed"
output:
"test_bed/{sample}.lc_extrap"
params:
"-v" #optional parameters
log:
"logs/test_bed/{sample}.log"
wrapper:
"0.67.0/bio/preseq/lc_extrap"
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.
