This is a free program for taking a good visual look at data that you have recorded using a Deuteron neural or audio logger. It allows you to see graphs of neural, motion sensor, and audio data (as well as other types if applicable) . It provides you with the ability to see your signals, apply filters of your choice to them, and to view spikes by applying a threshold to the filtered data. It is not intended to be a substitute for a full spike-sorting utility, nor is it meant to provide a full scientific analysis that is generally required for a complete analysis of such a data set. If there are features that you would like to see in the next version or data formats that you would like the program to export, please write your suggestions to firstname.lastname@example.org.
