Summary:To provide a method for determining whether or not nematodes exhibit an attraction behavior from a captured image even when the container in which the nematodes are placed has a point-symmetrical or axisymmetric shape.SOLUTION: It is a taxis analysis method for analyzing the taxis of nematodes using a container provided with a reference point on the container or on a medium inside the container, that includes: a step to image the distribution of nematodes in the container after the nematodes and the subject's specimens are dropped into the container; a step to detect a position of a reference point object corresponding to the reference point contained in the image obtained by imaging; a step to determine an attraction area and an avoidance area based on the position; and a step to perform taxis analysis using objects of nematodes in the attraction area and the avoidance area that are determined.SELECTED DRAWING: Figure 1 【課題】線虫が載置される容器が点対称または線対称の形状であっても、撮像された画像から線虫が誘引行動を示しているかを判断する方法を提供する。【解決手段】容器または容器内の培地に基準点が設けられた容器を用いて、線虫の走性解析をする走性解析方法であって、線虫及び被験者の検体が容器に滴下された後に、容器内の線虫の分布態様を撮像するステップと、撮像して得られた画像内に含まれる、基準点に対応する基準点オブジェクトの位置を検出するステップと、位置を基準に、誘引領域と忌避領域を決定するステップと、決定された誘引領域及び忌避領域における線虫のオブジェクトを用いて、走性解析を実行するステップと、を有する。【選択図】図1
