This is to announce an
alpha version of a new genetic map viewer, CMap-js. We intend this as a
replacement for CMap, which has served researchers well for a long time,
but which lacks the kind of interactivity that modern client-side web
technologies allow – and which won’t scale well with larger datasets.
With the caveat (again) that this is an early-release version, and not feature-complete ...
Check out the look-and-feel of the application here: https://legumefederation.org
(from the "CMap-js" button). Try clicking and dragging over the blue
map background and on the marker lists or the QTL features on the right.
of our design objectives are: flexible configuration; simple data
formats (accepting CMap tabular data for backward compatibility),
ability to pass in data via API (no database requirement and including
cross-site or user generated maps), minimal use of external libraries,
ease of installation, high interactivity (panning, zooming, clicking,
adding or removing maps, etc.), and scalability to a very large number
of markers. Theses structural goals are in addition to the ability to
compare maps, ability to display region data (QTLs, GWAS, etc.), the
ability to represent genetic-genomic comparisons (both within and
cross-species), and the ability to represent relations between features
for any given map. We still have quite a large set of features to add,
but please let us know if there are things that you would particularly
like to see.
