Data Aquisition

The data acquisition system is developed by a Tufts Graduate student.

-Flies are temporarily put to sleep with carbon dioxide and placed within trays

-Cluster trays of 6-12 are placed against a white backdrop and a camera records the movement of the flies. The environment is kept as constant as possible in order to not disturb the flies.

-LabView software first use edged detection to find the cluster container locations.

-The program runs through a series of tests to identify the flies

-The system runs at 15-16 frames per second reading about 85% correct data with invalid data skipped, corresponds to a average of 2 times per second.

-Data is then saved in 100 point batches to a tab delimiter file

-The result is a spreadsheet file with the coordinate locations of the tray edges and a spreadsheet file of the times and x and y positions of the flies. This data is loaded to a separate program for analysis.
