Nika is an Igor Pro ‐based package for correction, calibration and reduction of two‐dimensional area‐detector data into one‐dimensional data (`lineouts'). It is free (although the user needs a paid license for Igor Pro ), open source and highly flexible. While typically used for small‐angle X‐ray scattering (SAXS) data, it can also be used for grazing‐incidence SAXS data, wide‐angle diffraction data and even small‐angle neutron scattering data. It has been widely available to the user community since about 2005, and it is currently used at the SAXS instruments of selected large‐scale facilities as their main data reduction package. It is, however, also suitable for desktop instruments when the manufacturer's software is not available or appropriate. Since it is distributed as source code, it can be scrutinized, verified and modified by users to suit their needs.
