Importing data

Two SAS files for importing data. The files read the files for individual insects, extract the essential elements, and return a single file That has all the insects. The file has three variables: insect number, waveform, and duration. This contains all the information present, and all other variables can be calculated from these numbers. Note that this format avoids the problem with uncertainties regarding a TBF variable. TBF is time from beginning of file. It might be times from the beginning of a behavior or the end of a behavior. Both options work, but invites confusion if different people use different formats.

用于数据导入的两个SAS文件。这两个文件可读取针对单头昆虫的数据源文件，提取核心数据要素后整合为一份涵盖全部昆虫相关数据的单一文件。该文件包含三个变量：昆虫编号、波形与时长。其涵盖了所有现有信息，其余所有变量均可通过这三个变量计算得到。需注意，此格式可规避TBF（time from beginning of file）变量相关的不确定性问题。TBF即文件起始时刻起算的时间，该变量既可指代从某行为起始时刻起算的时间，也可指代从某行为结束时刻起算的时间。两种定义方式均具备可行性，但不同使用者采用不同定义标准时极易引发混淆。
