How and when are Ensembl databases built?
When a new assembly is available, the process starts with loading the assembly sequence into a new database. Analyses like Blast searches, repeat masking, Marker-EPCR and ab initio gene predictions (Genscan) are run and as soon as these initial analyses are finished, the results get publicly released as a pre-Ensembl database. After the initial analyses, the gene build starts. Genewise is used to predict genes on the basis of homology matches between the genomic sequence and protein sequences from zebrafish and other species. After the gene build, additional data is added. For the whole current spec of available information please check Ensembl. When these processes is finished, the data gets released as an Ensembl database replacing the previous one and the pre-Ensembl database will be taken off the web pages. Ensembl databases are released every month to reflect changes in the underlying code and the featured data. This means that the content of an Ensembl database can slighty change
