Hi,

I'm trying to use Batch Entrez (https://www.ncbi.nlm.nih.gov/sites/batchentrez) to look up the identifiers below, but although UID are recognised (and return records in the CBI database) - the output is empty.

Any idea why?
Thanks! Reproducible example (to copy paste in a .txt document): 

    KF771749.1
    KF153813.1
    MG737737.1
    MK091921.1
    MG173246.1
    JQ073586.1
    HM402114.1
    MG851790.1
    KP317997.1
    MG737738.1


Using EntrezDirect:

    $ esearch -db nuccore -query "MG737737" | elink -target taxonomy | esummary | xtract -pattern DocumentSummary -element TaxId | xargs -n 1 sh -c 'efetch -db taxonomy -id "$0" -format xml' | xtract -pattern Taxon -block "*/Taxon" -unless Rank -equals "no rank" -tab "\n" -element Rank,ScientificName
