v1.6.6 Release

· 4 min read

We are pleased to release v1.6.6!

This contains several updated synteny features, including:

  • load .chain files from UCSC
  • load .delta files from mummer
  • load .anchors and .anchors.simple files from MCScan from the GUI
  • ability to "rectangularize" the dotplot view and improved dotplot view overviews (shows total bp of selected regions)

Note: MCScan functionality existed internally but was not easy to use. The configuration schema for MCScan anchors files changed also to load the .bed files at startup. See the config guide for details

We also have an updated configuration editor GUI with collapsible sections

A number of alignments track look and feel improvements were also added. The scale bar was made to just list the min and max values when the height is small, clip indicator position when horizontally flipped was fixed, and the headroom was removed making the snpcoverage take up the full height of the small area it uses.

There have also been some changes to how internet accounts work. If you use one of the built-in accounts like Google Drive or Dropbox, there's no need to change anything. If you've implemented your own internet account, though, see #2725 for more details.
