Hi Jeong-Woon,

Welcome to our community forum!

I think we need some more information to help you with the training.

Can you confirm what version of the training of the training materials that you’ve checked out? You can use git rev-parse --short HEAD to get the commit hash?

Can you use tree and confirm that the file hello-nextflow/data/bam/reads_mother.bam is in the correct place in your local file system?

Can you replace the ${projectDir} in the params.reads_bam with the absolute path to the file in you’re using and see if that fixes it?
