Snakemake error AttributeError: 'Resources' object has no attribute 'tmpdir'

Question

[Begonia_pavonina]

I have built a Snakemake pipeline which has been designed for paired-end reads. I have made a trial with single-end reads, and got this error. I am not sure it is related to the change of reads design, and to be honest I do not understand the error message! Is it looking familiar to anyone?

rule bwa_mem:           
    input: reads/Beg9_1.fastq.gz, genome.amb, genome.ann, genome.bwt, genome.pac, genome.sa

Shutting down, this might take some time.
Exiting because a job execution failed. Look above for error message

Can you post the code for the rule?

Here it is:

# https://snakemake-wrappers.readthedocs.io/en/stable/wrappers/bwa/mem.html
rule bwa_mem:
        input:
                reads=["reads/{sample}.fastq.gz"],
                idx=multiext("genome", ".amb", ".ann", ".bwt", ".pac", ".sa"),
        output:
                "mapped/{sample}.bam",
        log:
                "logs/bwa_mem/{sample}.log",
        params:
                extra=r"-R '@RG\tID:{sample}\tSM:{sample}'",
                sorting="none",  # Can be 'none', 'samtools' or 'picard'.
                sort_order="queryname",  # Can be 'queryname' or 'coordinate'.
                sort_extra="",  # Extra args for samtools/picard.

        wrapper:
                "v2.9.1/bio/bwa/mem"

I do not think it is an error related to the single-end read dataset. Having a look at the wrapper, single-end read data are mentioned in the wrapper code and accepted by BWA. https://snakemake-wrappers.readthedocs.io/en/stable/wrappers/bwa/mem.html

Once again, I am clueless about this error.

Since it's complaining about tmpdir and resources my only guess would be to try explicitly defining it in the resources directive.

resources:
    tmpdir='/path/to/tmp/dir'
