单细胞转录组确实是利器,但我们大多只利用了表达的信息,而从reads到表达之间的信息完全被我们忽略了. 最近nature发了一篇单细胞方法类文章,讲得就是如何利用RNA velocity来做细胞发育路径的推断. velocyto velocyto-notebooks RNA velocity of single cells 首先需要了解一些基本概念: RNA velocity:the time derivative of the gene expression state—can be dire

NGS ngs(hisat,stringtie,ballgown) #HISAT (hierarchical indexing for spliced alignment of transcripts) is a highly efficient system for aligning reads from RNA sequencing experiments. HISAT uses an indexing scheme based on the Burrows-Wheeler transfor
Directional RNA-seq data -which parameters to choose? REF: https://chipster.csc.fi/manual/library-type-summary.html Directional RNA-seq methods are gaining popularity. Several protocols and products are available for the library preparation step, and
单细胞在脑科学方面的应用 Session 1: Deciphering the Cellular Landscape of the Brain Using Single Cell Transcriptomics Single cell/nucleus transcriptomics has emerged as a powerful approach to classify cell types and dynamic cell states in any multicellular organ
在做基因表达分析时必然会要做差异分析(DE) DE的方法主要有两种: Fold change t-test fold change的意思是样本质检表达量的差异倍数,log2 fold change的意思是取log2,这样可以可以让差异特别大的和差异比较小的数值缩小之间的差距. Let's say there are 50 read counts in control and 100 read counts in treatment for gene A. This means gene A is
