The UpDown Reader software allows for the efficient processing of 50% von Frey thresholds based on the up-down method for 2 species (mouse, rat) and 2 forms of stimulus (plantar, visceral). Templates for each species are provided along with the application.

Given a PDF input, the software identifies and extracts the grid of von Frey assessment tables, recognizes the handwritten sequences entered in each of them, and computes the 50% response thresholds according to the selected species and stimulus. The computed values for each animal is reported on the interface; the output can be saved to a csv file.
