Hello everyone,

Could you please assist me in resolving the error message that appears during my 3 steps of NGS data analysis? Your help would be greatly appreciated. I used the cmd in python src/assembly_and_polish.py

Constructing minimap index.
[E::fai_build3_core] Failed to open the file /home/mdehspk5/HCMV_glycoproteins_pipeline/tmp/denovo_assembly/Merged_fastq_BC18/UL_assm/reads_final.fa

Thank you.
