Fly science

At long last, years of hard work in the field of Drosophila research has met with the fruition of this publication…maybe one day I will blog about the challenges of associated with this field of research.  Now is not the time, but suffice to say, I will say this….if a paper on fruit fly phenotype is published and nothing about the husbandry, nutrition, and rearing conditions are provided, the research should be taken with huge grain of salt.  Context is everything.

Survivorship Curves depend on the type of diet

 

Thermimage update

At long last, I’ve spent time fixing some sloppiness in my R package, Thermimage, as well as added functions for importing and exporting thermal images and videos.  Partly still beta testing it on github for the time being but will eventually upload it CRAN once finalised.

Meanwhile for those using thermal imaging but frustrated at not being able to import or analyse images in an open source environment, consider trying this out:

Here is the proof of the exported raw file imported into ImageJ:
