[ensembl-dev] canonical transcript

[Sung Gong]

Hi,

The 'gene' table contains a column 'canonical_transcript_id' which is
a foreign key to the 'transcript' table.

My questions are:
1. How do you define whether a transcript is canonical or not? Any
documentation on the Ensembl web site?
2. Within the 'gene' table, all the 'canonical_annotation' column are null?
3. I could not find 'translation_translation' table, whereas there is
a column 'canonical_translation_id' in the 'transcript' table.
4. How do you define a canonical translation?

Cheers,
Sung
