描述----------Description----------
Determines row or column delimiters for spot locations
确定点位置的行或列分隔符
用法----------Usage----------
参数----------Arguments----------
参数：chan1
matrix of pixel intensities from the first channel.
从第一通道的像素强度的矩阵。
参数：chan2
matrix of pixel intensities from the second channel.
从第二通道的像素强度的矩阵。
参数：rows
number of spots in a row of the image block.
在一排的图像块点的数量。
参数：cols
number of spots in a column of the image block.
斑点数列的图像块。
参数：span
Window size for locating peak signals. This can be of length 2, in which case the first value is interpreted as a window size for the rows and the second as a window size for the columns. A default is estimated from the image dimension and number of spots.
寻找峰值信号的窗口大小。这可以是长度为2，在这种情况下，第一个值被解释作为一个窗口大小的行和列的窗口大小作为第二。默认情况下，预计从图像尺寸和斑点的数量。
参数：show
logical variable indicating whether or not to display the gridding result.
逻辑变量表示是否显示网格化的结果。
值----------Value----------
A list with two elements, rowcut and colcut giving delimiters for the row and/or column gridding of the slide. The indexes indicate the start of a segment of the grid, except for the last one, which indicates the
具有两个元素的列表，rowcut和colcut给行和/或幻灯片网格的列分隔符。该指数表明电网板块的启动，除了最后一个，，这表明
