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.

-----

**Interpolation types**

- **Nearest** uses the value of the nearest base pair that has data
- **Linear** uses a linear interpolant between the values of the nearest two probes
- **Cubic** uses a cubic interpolant between the values of the nearest two probes

**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.
