A computer program, "SeinFit," was created to determine the Seinhorst equation that best fits experimental data on the relationship between preplant nematode densities and plant growth. Data, which can be entered manually or imported from a text file, are displayed in a data window while the corresponding graph is shown in a graph window. Various options are available to manipulate the data and the graph settings. The best-fitting Seinhorst equation can be calculated by two methods that are both based on the evaluation of the residual sum of squares. Depending on the method, a range of values for different parameters of the Seinhorst equation can be chosen, as well as the number of steps in each range. Data, graphs, and values of the parameters of the Seinhorst equation can be printed. The program allows for quick calculation of the danaage threshold density - one of the parameters of the Seinhorst model. Versions written for Macintosh or DOS-compatible machines are currently available through the Society of Nematologists' World Wide Web site (http://ianrwww.unl.edu/ianr/plntpath/ nematode/SOFTWARE/nemasoft.htm).
创建了一个名为“SeinFit”的计算机程序,用于确定最符合种植前线虫密度与植物生长关系实验数据的Seinhorst方程。数据可以手动输入或从文本文件导入,在数据窗口中显示,同时相应的图表在图形窗口中显示。有各种选项可用于处理数据和图表设置。可以通过两种基于残差平方和评估的方法计算最佳拟合的Seinhorst方程。根据方法的不同,可以选择Seinhorst方程不同参数的一系列值,以及每个范围内的步数。Seinhorst方程的数据、图表和参数值可以打印。该程序允许快速计算损伤阈值密度——Seinhorst模型的参数之一。目前,通过线虫学家协会的万维网站点(http://ianrwww.unl.edu/ianr/plntpath/nematode/SOFTWARE/nemasoft.htm)可以获取为Macintosh或DOS兼容机器编写的版本。
