Coherent Maps Data

All data is in either MATLAB .mat format or images in .TIF format. Data includes processed neuronal activity derived from single-photon calcium imaging in mice, as well as positional information while mice explore one of two arenas. Folder names indicate the name of the arena, their chronological order within a day, and the arena rotation (or not) from the standard configuration on the first session of day 1 and day 2 (e.g. "2 - octagon 90CW" indicates that folder contains data from the second session recorded in the octagon arena and that the arena was rotated 90 degrees clockwise). NeuronROIs.mat: contains neuron ROIs for a given session recorded using calcium imaging. Pos_align.mat: position data (x_adj_cm and y_adj_cm) in centimeters aligned to imaging data. PSAbool = putative spiking activity (rows = neurons, columns = timestamps), RawTrace and LPtrace are the same as PSAbool but for full calcium traces and low-pass filtered calcium traces. ICmovie_min_proj.tif: minimum projection of imaging movie for a given session, used for image/neuron registration between sessions.所有数据均采用MATLAB .mat格式存储，或为.TIF格式的图像文件。本数据集包含经处理的小鼠单光子钙成像神经元活动数据，以及小鼠在两种行为箱之一中探索时的位置信息。文件夹名称标注了该数据所属的行为箱名称、单日实验内的时序顺序，以及与第1天和第2天首次实验会话的标准配置相比，行为箱是否旋转及旋转方向。例如"2 - octagon 90CW"表示该文件夹包含八角形行为箱中记录的第2次实验会话数据，且该行为箱曾顺时针旋转90度。 NeuronROIs.mat：存储本次实验会话中通过钙成像记录的神经元感兴趣区（Region of Interest, ROI）数据。 Pos_align.mat：存储与成像数据对齐的位置数据，单位为厘米，包含x_adj_cm与y_adj_cm字段。 PSAbool：存储推定锋电位活动数据（行代表神经元，列代表时间戳）；RawTrace与LPtrace的存储格式与PSAbool一致，分别对应完整钙信号轨迹与低通滤波后的钙信号轨迹。 ICmovie_min_proj.tif：存储本次实验会话成像视频的最小强度投影图，用于实验会话间的图像与神经元配准。
