Status flags for path classification and lineage construction.

The first 6 flags (bold) determine terminal starting / end points of paths. The next 2 flags indicate starting / end points which are in need for completion through either connection, correction, or removal from the tracking evaluation. Although the last flag ("merged") is not used to classify the ends of a path, it implies both a set "lost start" and "lost end" flag.*) The vicinity of the border is defined such that the distance between the centroid of the cell and the image border is smaller than a minimum distance (typically about 25–40 pixel, corresponding roughly to 50 µm).前6个（加粗）标记用于确定路径的终端起始点与结束点。后续2个标记则代表需要通过连接、修正或从跟踪评估中移除等操作完成标注的起始/结束点。尽管最后一个标记（"merged（合并）"）并非用于对路径端点进行分类，但它同时隐含了"起始点丢失"与"结束点丢失"两种状态。边界邻域的定义为：细胞质心与图像边界之间的距离小于某一最小阈值（通常约为25至40像素，大致对应50微米）。
