I want to use DIAMOND for my metagenome Functional analysis. As the instruction, I have to download NCBI nr database (ftp://ftp.ncbi.nlm.nih.gov/blast/db/). Unfortunately, my internet connection is not very stable, so I have to download a multiple nr file nr.**.tar.gz instead of a nr single gz file using these code:
wget 'ftp://ftp.ncbi.nih.gov/blast/db/nr.01.tar.gz'; cat nr.**.tar.gz | tar -zxvi -f - -C
After that, I got a lot of file in my output directory (~180Gb). I wonder how I can combine all these file into a single nr.faa just like in the DIAMOND manual.
Thank you all.
