Workshop announcement: Learning to effectively and efficiently use DARWIN The DARWIN Research Group at Eckerd College announces a workshop/tutorial "Learning to effectively and efficiently use DARWIN," to be held Saturday, October 10, prior to the 18^th Biennial Conference on Marine Mammals, in Quebec City, QC, Canada. Workshop participants will learn to install and use DARWIN, a freely available photo-identification software package, to create a catalog of dorsal fins images and then compare images of newly sighted individuals against the catalog. We will also introduce the use of various software features that facilitate the sharing of data between or within research groups and enable the output of sighting data for input to other software packages. As a part of this workshop, copies of the current DARWIN software will be distributed and installed on the laptop computer of each participant. The hands-on workshop will provide step-by-step instruction on the most important features of the software, and pointing out various tips and tricks to get the best performance from it. There will be time at the end of the workshop when participants can experiment with what they have learned and have an opportunity to have questions answered, as they arise. We anticipate that this workshop will be useful to researchers interested in training others or in using the software themselves to facilitate the photo-identification process.
