嗯，都是整数

王老师，您好，我在用TrajStat做聚类分析的时候出现了这个问题，我运行example的时候是可以运行的。我想请教下原因是什么，附上错误的提示信息

很有可能是某些轨迹节点数不够造成的，有些轨迹可能由于气象数据缺失的缘故追踪得不全。或者你重新计算那些轨迹，或者在聚类的时候忽略掉那些轨迹。在轨迹计算界面中你看看Point number对不对？如果是正确的，你可以选中Ignore the data lines with abnormal point number，然后再聚类（会忽略掉节点数异常的轨迹）。

老师，我本来那个csv文件里面放了多个字段有PM2.5、PM10等，我把他分成单个字段多个文件然后分别加载进去就没问题了。就是在那个add data to Trajectory那一步。

王老师，我想追问下，point number指的是什么

轨迹（线）是由点组成的，缺省的话是每个小时一个点。Point number指的每条轨迹的点数，比如做24小时的后向轨迹，点数应该是25。聚类分析要求所有轨迹的点数是一致的。

学习了

楼主遇到的一个问题我也遇到了，最后也是像老师建议的忽略异常数据得以解决。
这篇帖子学习氛围很浓
