• How to do a partial expand in Snakemake? 2回答

是否可以使用带通配符的snakemake并展开：

rule a:
    input:
        "input/{first}.txt",
        expand("data/{second}.txt", second=A_LIST)
    output:
        expand("output/{first}_{second}, second=A_LIST)

Answer 1

如果您的模式同时包含通配符和变量，请使用双括号作为通配符。例如，expand("output/{{first}}_{second}", second=A_LIST)

A_LIST = ['1', '2']

rule all:
    input:
        expand("output/abc_{second}", second=A_LIST)

rule a:
    input:
        "input/{first}.txt",
        expand("data/{second}.txt", second=A_LIST)
    output:
        expand("output/{{first}}_{second}", second=A_LIST)
    shell:
        "touch {output}"
