INTRODUCTION

When a developer is ready for a new assembly to be released, the QA team (usually an individual of) will QA and release the assembly. This wiki section exists as a guide for the assembly QA and release process.

CHANGE HAPPENS

As time goes on, please update this section as things change!

For the UCSC Genome Browser QA Team, there are two types of genome assemblies:

1. New species: Assembly for a species that is not already exisiting as a browser.
2. New version for exisiting species: Assembly version for a species that already exists as a browser.

When a new or updated assembly is ready to QA, the QA team should perform the following steps, outlined in this guide.

Notes about assembly source

From Hiram, 10/2016:

While genbank and refseq assemblies can be claimed to be 'identical' that just means they use the same sequence. The names for everything are different, aptMan1 has contig names of the format NW_013982187v1 which is a RefSeq identifier.

galGal5 is a RefSeq assembly GCF_000002315.4 It does have the chrM/NC_001323.1

RefSeq assemblies often are delivered with chrMt, although not always (sometimes none exists). Genbank assemblies are almost always delivered *without* a chrMt

RefSeq assemblies are delivered with NCBI gene predictions, Genbank assemblies do *not* have gene predictions.

Hence, whenever possible it is preferable to use RefSeq assemblies since they have that extra stuff. This is a recent innovation at UCSC, we (==I) always used to use GenBank assemblies because I was under the mistaken impression that somehow that was the gold standard 'official' assembly. Not true at all. Live and learn, however slowly.
