At now, the majority of approaches rely on manual techniques for annotating cell types subsequent to clustering the data obtained from single-cell RNA sequencing (scRNA-seq). These approaches require a significant amount of physical exertion and depend substantially on the user's skill, perhaps resulting in uneven outcomes and inconsistency in treatment. In this paper, we provide a computer-assisted interpretation of every single cell of a tissue sample, along with an in-depth exploration of an individual cell's molecular, phenotypic and functional attributes. The paper will also perform k-means clustering followed by silhouette validation based on similar phenotype and functional attributes, and also, cell type annotation is performed, where we match a cell's gene profile against some known database by applying certain statistical conditions. Finally, all the genes are mapped spatially on the tissue sample. This paper is an aid to medicine to know which cells are expressed/not expressed in a tissue sample and their spatial location on the tissue sample.
目前,大多数方法在对从单细胞RNA测序(scRNA-seq)获得的数据进行聚类之后,依靠手工技术来注释细胞类型。这些方法需要大量的体力劳动,并且在很大程度上依赖于用户的技能,这可能导致结果参差不齐以及处理过程中的不一致性。在本文中,我们对组织样本中的每个单细胞进行计算机辅助解读,并深入探究单个细胞的分子、表型和功能属性。本文还将进行k均值聚类,随后基于相似的表型和功能属性进行轮廓验证,并且还会进行细胞类型注释,即通过应用某些统计条件将细胞的基因谱与一些已知数据库进行匹配。最后,所有基因在组织样本上进行空间映射。本文有助于医学了解在组织样本中哪些细胞表达/未表达以及它们在组织样本上的空间位置。
