Reference genome error

[dbajpp0]

I was unable to input the reference genome from local in despite of using fasta or fna.gz or xip file. Once complains about the format, then name, then, matching names etc ...
Could you please indicate which is the format of the input file with the reference genome and how to input it from config.yaml or from samples.csv. My reference genome input file is zip and contains two files, fna and gbff files.
Thanks in adavance,
Joan Pons
