Dimension reduction software tools | Single-cell RNA sequencing data analysis

Offers a method for dimensionality reduction based on parametrization. t-SNE parametrizes the non-linear mapping between the data space and the latent space by means of a feed-forward neural network. This software is implemented into seven different languages, and, additionally, as Barnes-Hut and parametric implementation. This tool is fitted for the visualization of high-dimensional datasets.

Offers a platform for data exploration either in biomedical and nonbiomedical context. PHATE is a standalone software, available in three different programming languages, that provides unsupervised data-driven visualization of both local and global structures in high dimensional data. It can be used with several datatypes such as single-cell RNA sequencing, CyTOF, image data, and connectivity data like social networks or HI-C DNA contact maps.

An easy-to-use application for microarray, RNA-Seq and metabolomics analysis. For splicing sensitive platforms (RNA-Seq or Affymetrix Exon, Gene and Junction arrays), AltAnalyze will assess alternative exon (known and novel) expression along protein isoforms, domain composition and microRNA targeting. In addition to splicing-sensitive platforms, AltAnalyze provides comprehensive methods for the analysis of other data (RMA summarization, batch-effect removal, QC, statistics, annotation, clustering, network creation, lineage characterization, alternative exon visualization, gene-set enrichment and more).

Facilitates the analysis of cellular heterogeneity, the identification of cell types, and comparison of functional markers in response to perturbations, based on a versatile method. SPADE helps to organize high-dimensional cytometry data in an unsupervised manner, and to investigate natural and pathogenic cellular heterogeneity for biological insight. The SPADE algorithm consists of four components: (i) density-dependent downsampling, (ii) clustering, (iii) linking clusters with a minimum spanning tree, and (iv) upsampling to restore all cells in the final result. This modularized process allows more efficient sub-algorithms to replace the current components. In this sense, SPADE can be viewed as a framework for cytometric data analysis and visualization that has the capacity to be evolved and adapted.

Allows users to analyze single-cell gene expression experiments. Monocle can realize differential expression analysis, clustering, visualization, and other useful tasks on single-cell expression data. The software enjoins individual cells according to a defined progress through a biological process, without knowing ahead of time which genes define progress through that process. It is designed to work with RNA-Seq and quantitative polymerase chain reaction (qPCR) data, and implements Census and BEAM tools.
