Problem with running test of nf-core/rnaseq

Question

[Deepblue]

Hello,

I was trying to run nf-core/rnaseq test for the 1st time. It stops half-way through with the following error after rounds of trials:

Error executing process > 'NFCORE_RNASEQ:RNASEQ:PREPARE_GENOME:BBMAP_BBSPLIT'

Caused by:
  Process `NFCORE_RNASEQ:RNASEQ:PREPARE_GENOME:BBMAP_BBSPLIT` terminated with an error exit status (1)

Command executed:

  bbsplit.sh \
      -Xmx6g \
      ref_primary=genome_gfp.fasta \
      ref_sarscov2=GCA_009858895.3_ASM985889v3_genomic.200409.fna ref_human=chr22_23800000-23980000.fa \
      path=bbsplit \
      threads=2 \
      build=1

  cat <<-END_VERSIONS > versions.yml
  "NFCORE_RNASEQ:RNASEQ:PREPARE_GENOME:BBMAP_BBSPLIT":
      bbmap: $(bbversion.sh 2>&1)
  END_VERSIONS

Command exit status:
  1

Command output:
  Error occurred during initialization of VM
  Could not reserve enough space for 6291456KB object heap

I don't know why it's like this and how to solve this issue so that I can proceed to analysis of my own datasets. I am running the workflow on HPC with memory of 50 G. Any response is greatly appreciated!

If you are not trying separate reads from multiple genomes (e.g. PDX data) then you should use https://nf-co.re/rnaseq/parameters#skip_bbsplit option.

Best to ask in the nf-core slack https://nf-co.re/join in the rnaseq channel.
