GRF_F_ML_RAW_left

The file is structured as a matrix with T rows × K columns (T=8,819; K=216). Each row holds the data of one gait trial. The first column identifies each dataset (“DATASET_ID”), the second column each participant (“SUBJECT_ID”), the third column each gait analysis session (“SESSION_ID”), and the fourth column each single gait trial within a session (“TRIAL_ID”). The remaining columns contain the values of the medio-lateral GRF signals for each gait trial. Note that due to the non-normalized nature of the data and the resulting different time-series lengths in the “RAW” files, non-available numbers have been replaced by “NaN” to maintain a constant matrix-dimension.本数据集文件采用矩阵结构，包含T行×K列（T=8819；K=216）。每一行承载一次步态测试的全部数据。第一列为数据集标识（"DATASET_ID"），第二列为受试者标识（"SUBJECT_ID"），第三列为步态分析会话标识（"SESSION_ID"），第四列为单次会话内的单一次步态测试标识（"TRIAL_ID"）。其余列均存储各次步态测试的 medio-lateral 地面反作用力（mediolateral GRF）信号数值。值得注意的是，由于原始（RAW）数据未经过归一化处理，导致各"RAW"文件的时序长度存在差异，因此将缺失值替换为"NaN"以维持矩阵维度的一致性。
