Project AUTOSECT "Exploratory Interdisciplinary Synergy Programme" - NNF20OC0064677Principal Investigator: Michael Krogh Jensen; Team Members: Guy Theraulaz, Silke SachseResearch Organization: Technical University of Denmark01 MAR 2021 -- 29 FEB 2024 -- Funding Value: 4.738.765 DKKDataset-23x1fly-raw.zip: set of 23 (+1) files corresponding to the output generated by the tracking procedure* used to extract the trajectory of a single fly walking in a small circular dish of 8.5 cm of diameter.Dataset-23x1fly-processed.zip: set of 23 files resulting from the cleaning procedure, consisting of removing long time intervals where flies do not move and correcting tracking inconsistencies. Video: example of one video of a single fly walking in the circular dish.123.png: Quick view of the trajectory of the fly in the first 3 videos. x and y axes coordinates are in pixels, vertical z axis is in minutes.fig-1fly.eps: Characterization of fly's behavior by means of the probability density functions of the distance to the border r_w, the angle of incidence to the border theta_w (the angle is +/-90º if the border is at the right/left of the fly), the instantaneous speed, the heading angle change delta phi (phi is the heading angle, given by the direction of the velocity vector), and the density plot of the position of the fly during the experiment.*Tracking procedure: FastTrack -- https://github.com/FastTrackOrg/FastTrack

Dataset-23x1fly-raw.zip：包含23（+1）个文件，对应跟踪程序生成的输出结果，用于提取单只果蝇在直径8.5厘米的小型圆形培养皿中行走的轨迹。*跟踪程序：FastTrack，开源地址：https://github.com/FastTrackOrg/FastTrack
Dataset-23x1fly-processed.zip：包含23个经清洗处理后的文件，清洗步骤包括移除果蝇静止的长时间区间并修正跟踪过程中的不一致性
Video：单只果蝇在圆形培养皿中行走的示例视频
123.png：前3段果蝇行走视频的轨迹快速预览图，x、y轴坐标单位为像素，垂直z轴单位为分钟
fig-1fly.eps：果蝇行为特征表征文件，通过以下指标的概率密度函数及实验期间果蝇位置的密度分布图实现行为分析：到培养皿边界的距离r_w、入射至边界的入射角theta_w（若边界位于果蝇右侧/左侧，该角度为±90°）、瞬时速度、航向角变化量delta phi（phi为速度矢量方向对应的航向角）
