Accurate indexing of electron diffraction patterns (DPs) is a critical and enabling step in the nanostructure determination using electron diffraction. Here, we compare two automatic indexing algorithms for spot electron DPs from a known crystalline material, one is based on the normalized cross-correlation of simulated and experimental DPs and the other is based on Groth's triangle algorithm. The Groth's triangle algorithm offers better accuracy for indexing off zone axis DPs at the cost of significantly increased computer time. The comparison is made using electron DPs recorded from a nanostructured TiN thin-film sample.
