Snakemake和STAR

我开始使用Snakemake,但我觉得我缺少一些关键概念...

我拥有的是fastq文件的目录,我想在所有读取对上运行STAR。

我写了以下蛇文件:

import os
from glob import glob

experiment_name = 'swo-406'
scratch_data_base_dir="/rst1/2017-0205_illuminaseq/scratch"
scratch_data_dir = os.path.join(scratch_data_base_dir, experiment_name)

seqrun = '180413_NB501997_0054_AHTFJ3BGX3'
fastq_dir = os.path.join(scratch_data_dir, 'fastq', seqrun)
preprocessing_dir = os.path.join(scratch_data_dir, 'preprocessing', seqrun)
if not os.path.isdir(preprocessing_dir):
    os.makedirs(preprocessing_dir)

ref_base_dir = '/rst1/2017-0205_illuminaseq/data/references/Reference_Genomes/GRCh38.87'
ref_genome = os.path.join(ref_base_dir, 'Homo_sapiens.GRCh38.dna.primary_assembly.fa')
star_ref_dir = '/rst1/2017-0205_illuminaseq/scratch/swo-390/STAR_references/human'

log = os.path.join(preprocessing_dir, 'log.txt')

SAMPLES = set([os.path.basename(fastq_file.replace('_R1_001.fastq.gz', '').replace('_R2_001.fastq.gz', ''))
        for fastq_file in glob(os.path.join(fastq_dir, '*_R*_001.fastq.gz'))
        if not 'Undetermined' in fastq_file])

print(expand(os.path.join(fastq_dir, '{sample}_R1_001.fastq.gz'), sample=SAMPLES))

# Rule all is a pseudo-rule that tells snakemake what final files to generate.
rule all:
    input:
        expand(os.path.join(preprocessing_dir, '{sample}.Aligned.out.bam'), sample=SAMPLES)

rule star_map:
    input:
        read1 = expand(os.path.join(fastq_dir, '{sample}_R1_001.fastq.gz'), sample=SAMPLES),
        read2 = expand(os.path.join(fastq_dir, '{sample}_R2_001.fastq.gz'), sample=SAMPLES)
    output:
        os.path.join(preprocessing_dir, '{sample}.Aligned.out.bam')
    log:
        log
    shell:
        """
        STAR \
        --runThreadN 8 \
        --genomeDir {star_ref_dir} \
        --readFilesIn {input.read1} {input.read2} \

        --outFileNamePrefix {output} \
        --outStd Log \
        {log}
        """

这将输出:

如您所见,我获得了所有fastq文件作为STAR的输入,它没有像我期望的那样在样本中循环。我该怎么办?

答案 0 :(得分:1)

您需要定义{sample}中的rule all通配符。在下面的示例中,snakemake将针对示例A和B运行。

rule all:
    input:
        expand(os.path.join(preprocessing_dir, '{sample}.Aligned.out.bam'), sample=['A', 'B'])
