Synergistic benefits of group search in rats. Nagy et al.

Trajectory data of the experimental trials. Single search trails of 32 rats, and group search trials for 4 groups of 8 rats. Each rat was marked with a unique 3-color barcode on its back (R: Red, O: Orange, G: Green, B: Blue, P: Purple). Rat ID consists of 4-letter code: 3 letters show the color blobs from head to tail, 1 letter for sex (F: Female, M: Male). We video recorded all trials using a low light sensitive camera fixed to the ceiling (Sony HDR-AX2000, 2.9 × 1.8 m2 field of view, 1920×1080 resolution, 25 fps de-interlaced).
Recorded video sequences were analyzed off-line with a custom-written software to obtain individual positions and orientations (for details see the latest source code from https://github.com/vasarhelyi).

Data is separated to 3 zip files: SingleTrials1-7 zip file contains single trials from the familiarization period, SingleTrials8-13 zip file contains single search trials used in the main analyses, GroupTrials zip file contains group trails for 4 different groups of 8 rats.

File name provides additional information in the following format:
trial identification and number, "_", date of experiment (YYYYMMDD format), "_", rat ID or group ID (group IDs are M12, M23, F12, F34), "_", target ID (where the reward is located range between 1 and 16)
(for example: single1_20150817_BGPM_target11, group1_20150901_M12_target9)

Data structure is indicated in each file as a comment line (#frame number ID x y orientation). Data columns are separated by tabulator. "frame" indicates frame number of the video record, "number" is the number of individuals, "ID" is the 4 letter identification code of the rat, "x" and "y" indicates pixel coordinates, "orientation" is the main orientation of the marker (parallel to the body and pointing towards the head) given as an angle between -180 and 180 in degrees. When the automated recognition is failed the data contains "NaN".
