SnakeMake 파이프 라인을 시도하고 있는데 실제로 이해가 안되는 오류에 집착했습니다.Snakemake : Snakemake 파이프 라인의 MissingInputException
내가 입력 파일이있는 디렉토리 (raw_data)을 가지고 :
ll /home/nico/labo/etudes/Optimal/data/raw_data

PeriodicWildcardError in line 40 of /home/nico/labo/scripts/pipeline_illumina/snakefile_bwa_samtools.py:
The value _unsorted in wildcard sample is periodically repeated (sampleB_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted_unsorted). This would lead to an infinite recursion. To avoid this, e.g. restrict the wildcards in this rule to certain values.
가 목록에 표시 (출력의 종류의 첫 번째 줄) 내가 반드시 규칙 bwa_mem_to_bam에 와일드 카드로 장난 해요로 샘플이 제대로 감지, 그러나 나는 정말로 이유를 알지 못한다. .. 어떤 단서?
