NCBI - edirect suite to download all genome sequences associated with a query - troubleshooting Not sure if this is allowed but I cannot think of a better place to ask. I am attempting to download all genomic sequences from refseq associated with the query Peptostreptococcaceae. I have been been using the following command (based on some reading of the manual):

esearch -db nuccore -query "Peptostreptococcaceae" | efilter -molecule genomic -source refseq | efetch -format fasta


But I keep getting the following error

Unknown option: molecule   
Unknown option: source   
Must supply -query or -days or -mindate and -maxdate arguments on command

The issue here was I was using an older version of eDirect. There is no command to check version or updates. Your best bet is if you experience problems uninstall and reinstall.
