ABSTRACT
The identification of biologically meaningful domains is a central step in the analysis spatial transcriptomic data. Following Occam's razor, we show that simple PCA-based algorithm for unsupervised domain rivals performance ten competing state-of-the-art methods across six single-cell datasets. Our reductionist approach, NichePCA, provides researchers with intuitive interpretation and excels execution speed, robustness, scalability. code available at https://github.com/imsb-uke/nichepca.
