Downloading viral database

Question

[adnan.lahuf]

Dear Colleagues, I am planning to download the viral data from NCBI to be used later in my pipeline virus identification. However, I found several file types for nucleotide and protein data. My plan is to download every three types of files and combine them into one file. Thus, which of the following group of files should be selected for nucleotide data? viral.1.1.genomic.fna.gz; viral.2.1.genomic.fna.gz; viral.3.1.genomic.fna.gz viral.1.genomic.gbff.gz; viral.2.genomic.gbff.gz; viral.3.genomic.gbff.gz

Which of the following group of files should be selected for protein data? viral.1.protein.faa.gz ; viral.2.protein.faa.gz; viral.3.protein.faa.gz
viral.1.protein.gpff.gz; viral.2.protein.gpff.gz; viral.3.protein.gpff.gz In advance, I appreciate any comment.
Best Regards Adnan

For genomic sequences in FASTA format, use the files with suffix genomic.fna.gz, for genomic sequences in GenBank flatfile format, use the files with the suffix genomic.gbff.gz, and for protein sequence files in FASTA or GenPept flatfile formats use the files with suffixes protein.faa.gz and protein.gpff.gz, respectively.

To have a complete set of, say, viral genome sequences, you should download all of the genomic.fna.gz files and concatenate them.
