19 This tool will attempt to interpolate missing values (NaN) in a Wig file that result when converting discontinuous microarray probe data to Wig format. Stretches of missing data that extend longer than the allowed maximum will be left as NaN.

23 **Interpolation types**
|
|
|
24
|
|
|
25 - **Nearest** uses the value of the nearest base pair that has data
|
|
|
26 - **Linear** uses a linear interpolant between the values of the nearest two probes
|
|
|
27 - **Cubic** uses a cubic interpolant between the values of the nearest two probes

37 **TIP:** If your dataset does not appear in the pulldown menu, it means that it is not in Wig or BigWig format. Use the Converters -> IntervalToWig tool to convert Bed, BedGraph, or GFF-formatted microarray data to Wig format, then use this tool to interpolate the missing values between probes.
