Question

[saadleeshehreen]

Hi I am trying to get assembly number ( for example GCF_001166025.1 is for NZ_CQEB01000017.1) for 100 genomes with the following command. The command previously work for me but today giving some error. Anyone know what happen?

elink -db nuccore -id NZ_CQEB01000017.1 -target assembly|esummary|xtract -pattern DocumentSummary -element AssemblyAccession
