Use this text field to specify the number of neighboring markers to include in the sliding window. These values are used as the bandwidth for applying the p-value adjustment, that is the number of marker p-values on each side of each marker to include in the adjustment. A bandwidth of 0 is specified by default.

Type a single value in the text box to specify the number of markers to either side of each individual marker to include. For example, typing the value 1 in this text box indicates that sliding windows containing each individual marker and one marker on each side are formed for smoothing the p-values.

Use the statement: X to Y where X, Y, and Z are all nonnegative integers to specify a range of bandwidths. For example, type 3 to 5 to combine p-values by using bandwidths 3, 4, and 5, which create sliding windows of size 7, 9, and 11 markers, respectively.

Use the statement X to Y by Z, where X, Y, and Z are all nonnegative integers, to specify a more select range. For example, type 5 to 30 by 5 to combine p-values by using bandwidths 5, 10, 15, 20, 25, and 30, which create sliding windows of size 11, 21, 31, 41, 51, and 61 markers, respectively.

Combine both single values and ranges to generate specific bandwidths. For example, type 1, 2, 5 to 15 by 5, 18 to combine p-values by using bandwidths 1, 2, 5, 10, 15, and 18, which create sliding windows of size 3, 5, 11, 21, 31, and 37, respectively.
