In this paper we have investigated the alignment of nematic liquid crystal (NLC) molecules in homogenously oriented liquid crystal cells used for nematicons generation. We propose three different methods based on contrast evaluation, linear diffraction and nematicons generation. We showed that LC cell contrast evaluation is not enough from the perspective of nematicons generation. In order to select the best LC cell all of proposed methods should be combined with each other.
