MicroDraw.

An A0 poster which is designed for fabric print and can be cut and sewed into a bag.

The poster was presented at the 2015 Annual Meeting of the Organization for Human Brain Mapping (OHBM) in Hawaii, 14–18 June.

MicroDraw is a web application by NAAT to visualise and collaboratively annotate high resolution histology data. Annotations are vectorial, and you can use boolean operations to combine, subtract and split regions.

Point MicroDraw to your own DeepZoom data, or try a sample from the Web page! As a prototype of the platform, we created MicroDraw http://microdraw.pasteur.fr/.

Datasets

MicroDraw can use ontologies such as Neurolex to create community curated atlases, but also to annotate staining artefacts. We are currently hosting DeepZoom versions of several macaque brains from the Allen Institute for Brain Research, a 1 micron resolution section of a human brain from the BigBrain project, a 1 micron resolution section from a vervet monkey, and 0.25 micron resolution ferret data from project FIIND.

Application

MicroDraw is based on open source frameworks to ensure its maintainability and extensibility. The interactive multi-resolution visualisation is based on OpenSeadragon. The vectorial annotation is based on Paper. The concurrent versioning is based on Git.

MicroDraw is written in JavaScript, using HTML5, CSS3 and jQuery.
