Sometimes an error happens in the SAMTOOLS_FASTQ_NOGZIP process.
Error message:
ERROR ~ Error executing process > 'EMC_METAMICROBES:METAMICROBES:SAMTOOLS_FASTQ_NOGZIP (3)'
Caused by:
java.nio.channels.OverlappingFileLockException
Samtools fastq is included twice in the main workflow (but with different names), and probably the 2 processes with this tool generate output with the same name. Should be fixable by adding a prefix specific for each process with the tool via modules.config.
To bypass this, just run the workflow again, since it doesn't happen in every run.
