Expected processing time: about 3 hours (last updated 10 months).
This database contains all the prokaryotic genomes with complete and chromosome status in the NCBI Genome database, with the exception of 90 blacklisted genomes.
Jan-14-2019: 610 datasets were unlinked to rebuild the index. These datasets are mainly composed of Escherichia coli (n=185), Klebsiella pneumoniae (n=119), and Salmonella enterica (n=203). These and all new datasets will be subjected to a redudancy pre-filter starting in the next update to avoid including new datasets with high identity to existing entries.

Staphylococcus_aureus_subsp__aureus_CP025490, single plasmids, as well as
Cupriavidus_sp__NH9_NZ_CP017758, missing chromosome I.
Mar-06-2018: Blacklisted all Ca Tremblaya princeps and Ca Tremblaya phenacola datasets, with 50-100 predicted proteins and 100-200 kbp, which "cannot be considered a living organism".
Feb-14-2018: Initiated indexing by groups (for new genomes) to reduce impact on query datasets.
Feb-12-2018: Database update. Total reference genomes: 11,232. This update
is the first using the
miga ncbi_get method.
Jan-19-2018: Soft-unlinked the following datasets for indexing (will be included in the next update):
Jan-15-2018: Blacklisted 1 dataset composed exclusively of plasmid sequences
Halobacterium_salinarum_NC_002121. Total reference genomes: 10,637.
Dec-11-2017: Database update. 381 datasets eliminated and 884 datasets added. Total reference genomes: 10,638.
Nov-07-2017: The following datasets were soft-unlinked for indexing, but will be included in the next update:
Oct-12-2017: Database update. 129 datasets eliminated and 549 added. Total reference genomes: 10,224 post-update.
Aug-30-2017: Manually modified taxonomic rank

which was confusing MiGA into thinking it had a registered kingdom.
Aug-30-2017: A filesystem error caused an interruption of the following datasets, which will be unlinked for this update and re-downloaded in the next update:
Aug-15-2017: Database update. 75 datasets eliminated and 573 added. Total reference genomes: 9,559 (post-update).
Jul-07-2017: The following datasets were temporarily unlinked to complete
Natrialbaceae_archaeon_JW_NM_HA_15_NZ_CP019893. These datasets will be
included in the next update.
Jul-02-2017: The dataset
Stenotrophomonas_maltophilia_NC_001383 is only
composed of plasmid sequences and was manually removed.
Jun-23-2017: Database update. 91 datasets eliminated and 430 added. Total reference genomes: ,8724 (pre-update) - 9,063 (post-update).
May-12-2017: Database update. 222 datasets eliminated and 324 added. Total reference genomes: 8,622 (pre-update) - 8,724 (post-update).
Apr-25-2017: Database update. 7 datasets eliminated and 73 added. Total reference genomes: 8,557 (pre-update) - 8,622 (post-update). Database not indexed for this update.
Apr-21-2017: The following datasets were composed only of plasmids and were eliminated:
Candidatus_Tremblaya_princeps_LN998829: This dataset has a sequence named chromosome I, but it only contains 51 genes (140Kbp), so it's likely a plasmid.
Burkholderia_pseudomallei_NZ_CM007659 dataset only contains
the second chromosome of B. pseudomallei, resulting in a completeness of
2.7% (3 essential genes), it was therefore removed. The current database has
8,562 reference datasets.
Apr-17-2017: Database update. 87 datasets were eliminated and 218 datasets added. The following datasets were eliminated based on the previous update or completeness report (<1% and no 16S):
Total reference genomes: 8,437 (pre-update) - 8,563 (post-update).

Mar-06-2017: Database update. 239 datasets were eliminated and 663
datasets added. The dataset
Mycobacterium_tuberculosis_NC_025025 is only a
plasmid with 6,898 bp and no chromosome sequence, and was manually removed.
Total reference genomes: 8,015 (pre-update) -> 8,438 (post-update). The
Legionella_fallonii_LLAP_10_NZ_LN614827 was manually removed because
of a corrupt database file (it'll be incorporated in the next update),
resulting in 8,437 datasets.

distances of this dataset in the meantime.
