How Multiplexing Distorts Metabolic Phenotyping Data

Multiplexing metabolic signals causes significant data distortion. This post explains how, and gives you access to an amazing, interactive tool for exploring the metabolic data distortions produced by this practically universally-used technique! To save cost, [...]

Three reasons for misleading gas analyzer accuracy specifications

A funny thing happened on my way to helping a colleague make sense of the specifications of a metabolic phenotyping system. There were many strange things to mull over. Not the least of these were [...]

Data Visualizations you haven’t Seen Before…

OK, imagine a mouse in a cage. With Promethion, you can monitor that mouse's position to within a calculated centroid of 2.5 mm (several times higher resolution than legacy systems). You do this with an infrared light [...]

Measuring food uptake differentially

Let's say you need to measure the food uptake of an experimental animal, which of course could mean any creature, including you. For the sake of simplicity, imagine a mouse or a rat feeding intermittently [...]

Data, data, data!

This shows a day's worth of data from a single mouse in graphic form, recorded by a Promethion-C system for a research study on which I'm collaborating. The time resolution of the data set is one [...]

Automated behavior analysis: The basics of EthoScan

When mice (or rats) are wandering around their Promethion system cages and simply being mice (or rats), they interact with the various sensors in their cages – the mass sensors attached to their food and [...]

The future of metabolic phenotyping

The essence of metabolic phenotyping is accurate metabolic measurement. As a matter of convenience, cost and feasibility, practically all metabolic phenotyping systems operate in a multiplexed mode, in which a single gas analysis chain is [...]

Thoughts on Apple

I've written quite a lot of scientific data acquisition and analysis software, some of which - like Datacan and ExpeData - are in use in many laboratories around the world. I'm often asked: Why don't [...]
