genome assembly records not present in assembly_summary.txt

Question

[sapuizait]

Hi all

Gathered from various sources my lab has downloaded several E.coli assemblies from NCBI. Now, that I am looking to the data, I am trying to retrieve the metainfo. Even though for most of them I can get that from the assembly_summary file that can be downloaded from the NCBI FTP, there are some that do not exist even in the latest version of the file. Example: GCA_018564605.1 does not exist in the assembly_summary file but if I look for it in the NCBI portal, it is there! https://www.ncbi.nlm.nih.gov/datasets/genome/GCA_018564605.1/ Is it because the record is not curated? How can I retrieve these?

Thanks

If you have the accession numbers can you not use something like eutils?

Can you clarify what metainfo you are referring to?

The accession that you refer to does exist in GenBank assembly_summary file.
