Downloading human rrna fasta file from ncbi

Sorry, I can't post a comment with my reputation score. However, your command is downloading all sequences from the input file into a single fasta file. I believe that if you have a big bunch of sequences, it could be a little bit tricky after to manipulate that kind of file. Just by curiosity, do you have a trick to create one sequence per file using efetch? Sign up to join this community. The best answers are voted up and rise to the top.

Downloading a few sequences For this, you can use Entrez Direct as mentioned by dc BlueSky BlueSky 2 2 bronze badges. Whether you want a large number of files or just one file is, I guess, a personal choice. A multifasta file is fairly standard though. I don't think you can create individual files for each sequence using epost and efetch ; you will have to either use a bash script or postprocess the efetch output using the unix tool split.
