A Python-based pipeline for performing punctate quantitative analysis on C. elegans ventral cord fluorescence scans.

The first ionotropic glutamate receptor subunit to be characterized was found to play a key role in facilitating the worm’s nose-touch response. Mutations in this glr-1 interfere with the glutamatergic activity between sensory and command interneurons.

In order to localize these iGluRs, a functional fusion chimera between iGluRs and GFP was generated. In these transgenic worms, fluorescence can be observed in a punctate pattern along the ventral nerve cord. Functional glr-1::GFP proteins have proven to be invaluable in ascertaining the trafficking and recruitment of glr-1 containing receptors.

This program takes these fluorescence scans and translates user-provided tracings into punctate traces for analysis. It includes a built-in graphical user interface for ease of use and optimizes of previous draw scanners by implementing the Billauer algorithm for peak detection.
