Info • Chromera velia CCMP2878


The Chromera velia CCMP2878 genome assembly and gene models have not been determined by the JGI, but were downloaded from CryptoDB release 45 on October 31, 2019. In order to allow comparative analyses with other algal genomes sequenced by the JGI, a copy of this genome is incorporated into PhycoCosm. Please note that this copy of the genome is not maintained by CryptoDB and is therefore not automatically updated.

We applied filters to remove if present: 1) transposable elements, 2) pseudogenes, 3) alternative transcripts and overlapping models, and 4) unsupported short models. This resulted in removal of 7,635 models from C. velia and generation of the FilteredModels1 gene track. All published models are available in the ExternalModels track. The JGI Annotation Pipeline was used to add functional annotation to this genome.
