Computational Biology

The aim is to understand how patterns of gene activity in biological organs influence the developing shape.

Hypothesis: gene activity independently regulates direction of growth. Formalised in the Growing Polarised Tissue Framework (cite). Implemented in GFtbox (cite) for developing ideas on growth and form. Start with a sheet of tissue (the canvas) with observed, or hypothetical patterns of growth factor activity. Grow the canvas in 3D under constraints of tissue continuity Compare with observed data quantitatively Downloads and more details on GFtbox	<sgallery width="140" height="200" showarrows="false" showcarousel="false" showinfopane="false" timed="true" delay="3000"> LabelledCropped GPT Snapdragon 2010-000570-0003 double.png LabelledCropped GPT Snapdragon 2010-000570-0002 triple.png LabelledCropped GPT Snapdragon 2010-000570-0001-Wildtype.png </sgallery> More on testing models

Produced by CT X-ray scanners, MRI and PET. Confocal microscopy and OPT (ref) used with fluorescent probes that monitor biological gene activity. Huge amounts of data potentially make viewing slow, but... To interact with the images we implemented VolViewer (cite) which exploits powerful graphics processors. Works with BioformatsConverter to read open and proprietary file formats Downloads and more details on VolViewer	<sgallery width="140" height="200" showarrows="false" showcarousel="false" showinfopane="false" timed="true" delay="4000"> Arabidopsis_Leaf_ATH8bbg.png </sgallery> More on 3D measurement
