Hi there, I have just downloaded some genome assemblies from NCBI that are assembled at the contig level, and they are in .fna format. From what I understand, after assembly into contigs, the next step in a genome analysis workflow is mapping back to where the contigs fit on the genome. I am using bbmap to do this. However, bbmap needs 'reads' as input files as well, and my files only have the assembled contigs in the .fna file. Do I need to redownload the raw reads to feed into this input? Or am I not understanding this workflow properly..
