The spikefinder challenge


Calcium imaging is one of the most widely used techniques to acquire data from large populations of neurons. Unfortunately, inferring action potentials from the measured calcium traces is not straightforward and algorithmically far from solved.

To make progress in this direction, we opened the spikefinder challenge at!

We collected a large dataset of simultaneous two-photon imaging and electrophysiologically records and made it available separated into training and test sets. We ask you to design your favorite algorithm and submit your results on the website!

What is your benefit?

  • You get to advance the community
  • All algorithms that beat state of the art will be included in an overview paper and you will be coauthor
  • The top three teams will win a 1200/500/300 EUR award sponsored by our partner ZEISS AG.

We look forward from receiving your submissions. The deadline is the 31st of March 2017.
