Metadata Files

The Metadata files contain metadata and behavioural data. The variables are: • acquisition_rate is a scalar describing the acquisition rate in Hz. • Pixel_size is a scalar describing the size of each pixel in microns. • Numb_patches is a scalar describing the number of patches in the experiment. • Patch_coordinates is a structure containing coordinate information about each patch. Patch_coordinates.data is a matrix in which each row represents a patch, and columns 5, 6, and 7 represent the X, Y, and Z positions (respectively) of that patch. • SpeedDataMatrix and SpeedTimeMatrix are vectors containing the wheel speed time series and times from the wheel encoder. • dlc_whisk_angle and dlc_whisk_time are vectors containing the whisking angle time series and times as determined via DeepLabCut.• wheel_MI is a matrix whose second column contains the wheel motion index time series as determined from the wheel cameras and whose second column contains the corresponding times. Note that this file may also contain variables extracted by now obsolete methods which were not included by the analysis in the paper (e.g., Whiskers_angle_0 for old whisker position detection, Axon_dFF for old grouping procedure). You can ignore these.本元数据文件包含元数据与行为学数据。相关变量说明如下： • acquisition_rate（采集率）：为标量值，描述以Hz为单位的采集速率。 • Pixel_size（像素尺寸）：为标量值，描述单个像素的尺寸，单位为微米。 • Numb_patches（补丁数量）：为标量值，描述实验中补丁的总数量。 • Patch_coordinates（补丁坐标结构体）：存储各补丁的坐标信息。其中Patch_coordinates.data为矩阵，每行对应一个补丁，第5、6、7列分别代表该补丁的X、Y、Z位置。 • SpeedDataMatrix（速度数据矩阵）与SpeedTimeMatrix（时间数据矩阵）：二者均为向量，分别存储滚轮编码器获取的滚轮速度时间序列与对应时间戳。 • dlc_whisk_angle（触须角度数据向量）与dlc_whisk_time（触须角度时间戳向量）：存储通过DeepLabCut检测得到的触须角度时间序列与对应时间戳。 • wheel_MI（滚轮运动指数矩阵）：为矩阵，其第二列存储由滚轮摄像头获取的滚轮运动指数时间序列，且第二列同时包含对应时间戳。 请注意，该文件可能还包含已废弃方法提取的变量，此类变量并未纳入本文的分析流程中（例如用于旧版触须位置检测的Whiskers_angle_0，以及用于旧版分组流程的Axon_dFF）。此类变量可忽略不计。
