• Filling out the template is required. Any pull request that does not include enough information to be efficiently reviewed may be rejected.

Description

This draft PR would update the way the synteny view handles data, obtaining a unique set of synteny regions in the main chromosome, and then ordering these in such a way that they are 'threaded' along it.

It would also update the info box shown when a chromosome lacks synteny regions in the selected other species.

It is a draft PR, pending testing of synteny views.

Views affected

This change could affect all synteny views.

The dataset most affected would be the Human self-synteny. For example:

• Chromosome 10 : sandbox vs live

Possible complications

None expected, though further checks are needed.

Merge conflicts

None detected
