Building on these promising approaches, we present Bento, an open-source Python toolkit for scalable analysis of spatial transcriptomics data at the subcellular resolution. Bento ingests single-molecule resolution data and segmentation masks, utilizing geospatial tools (GeoPandas [28], Rasterio [29]) ...
[2], Pandas [3], SciKit-Learn [4], Keras [5] and others. The gathered data is cleaned up, subjected to a series of transformations, analysed and results are either visualised or saved in human readable formats. Mostly, these arenon-cluster basedtechniques relying on the computing power ...
