samplesheet error

[AlcaArctica]

Description of the bug

I am getting a sample sheet error with the following sample sheet:

sample,fastq_1,fastq_2
HIC_ES_4,/lustre/projects/dazzlerAssembly/test_hic/SRR5339783_1.fastq.gz,/lustre/projects/dazzlerAssembly/test_hic/SRR5339783_2.fastq.gz

The error may be related to #152, but as there is only one line in my sample sheet it seems unlikely.

Another potential problem could be that our system does not have file locks. However, I thought I took care of that by using the -w /tmp/ flag. (/tmp/ does have file locks!).
Any other idea what I could try?

Perhaps singularity is missing some bind? (because of the message /tmp/1c/167b78c8be41694d24c476732df8e2 doesn't exist in container) Is it possible to specify a singularity bind?
I cant use docker, as we cannot install docker on our system.

Hi Alca,

I encountered the same issue. Did you find the solution for it?
Thanks,

Hi,
I think this is a general singularity issue, not really a samplesheet one.
Did you already use any other nf-core pipeline with singularity ?
