The following are a list of visualization tools that enable viewing and exploration of BICCN-generated data.
Azimuth (RRID:SCR_021084) is a web application that uses annotated reference dataset to automate processing, analysis, and interpretation of new single cell RNA-seq experiment. Azimuth leverages reference-based mapping, a pipeline that inputs a counts matrix of gene expression in single cells, and performs normalization, visualization, cell annotation, and differential expression. All results can be explored within the app, and easily downloaded for additional downstream analysis.

Brain Architecture (RRID:SCR_004283). The Brain Architecture portal, active since 2012, provides a virtual microscopic brain observatory spanning multiple species, including mouse, marmoset, human and zebrafinch, and data analysis tools. The project is creating mesoscale brain connectivity maps for the mouse and the marmoset. A peta-voxel data set, with thousands of brains injected with neuronal tracers to help visualize the mesoscale connectivity, are interactively viewable. Spatial distributions of specific cell types, histological reference brains and atlases across species are also presented.

Brain Cell Methylation Viewer (RRID:SCR_020954). Viewer for DNA Methylation Atlas of Mouse Brain at Single Cell Resolution. Browser to interactively explore single-cell methylome dataset including exploration of methylation diversity of one gene at single-cell or cell-type level, exploration of cell type composition of adult mouse brain dissection regions and anatomical structures, exploration of spatial distribution and methylation signature genes of one cell type.
Ecker Lab (https://ecker.salk.edu/), Salk Institute for Biological Studies
Described in paper by Liu et al. 2021.
Brainome Portal (RRID:SCR_018162). Genome browser viewer for single cell epigenomic and transcriptomic data (DNA methylation, ATAC-seq, RNA-seq) from mouse primary motor cortex. Search for genes to visualize genomic loci, including enhancers marked by peaks of chromatin accessibility and low DNA methylation.
Described in paper by Yao et al. 2021.
Mukamel Lab (https://brainome.ucsd.edu), UCSD Cognitive Science
cellxgene (RRID:SCR_021059) Created by the Chan Zuckerberg Initiative, cellxgene is a scalable, open source resource designed to make it easier for researchers without computational experience to easily share and explore single-cell datasets from various modalities in common formats. Users can visualize gene expression at the level of an entire dataset, or particular subset of cells to help identify cell types, which in turn can help identify diseases. Cellxgene enables plotting gene expression levels, or other features, against another gene to compare how these different genes are expressed across a dataset, and it integrates with existing tools like SciPy and Jupyter.

Cytosplore Viewer (RRID:SCR_018330) is an interactive visual analysis application (Windows and MacOS) for exploration of multi-species and cross-omics single cell data published in Allen Cell Types Database and for a growing number of single cell data resources of Brain Initiative Cell Census Network. Allows interactive exploration of cellular hierarchies, transcriptome wide gene expression and metadata of individual cells, and computation of differential statistics between cell selections or clusters, and across species. Integrates linkout to the UCSC genome browser for linked cross-omics, cross-species exploration between matched gene expression, chromatin state and DNA methylation data.

NeMO Analytics (RRID:SCR_018164) NeMO Analytics (nemoanalytics.org) is a web-based suite of data visualization and analysis tools, focusing single-cell data analysis. The portal allows users to visualize published or user-supplied multi-omic data across experiments and species side-by-side. Tools include cluster visualization based on expression/cell type, cluster comparison, projection of one dataset into another, identification of marker genes, comparison of marker genes across datasets and note taking.

NeuroMorpho.org (RRID:SCR_002145). Centrally curated inventory of digitally reconstructed neurons and glia associated with peer-reviewed publications that contains some of the most complete axonal arborizations digitally available in the community. Each cell is represented by a unique identifier, general information (metadata), the original and standardized ASCII files of the digital morphological reconstruction, and a set of morphometric features. It contains contributions from over 800 laboratories worldwide and is continuously updated as new morphological reconstructions are collected, published, and shared. Users may browse by species, brain region, cell type or lab name. Users can also download morphological reconstructions for research and analysis. Deposition and distribution of reconstruction files ultimately prevents data loss. Centralized curation and annotation aim to minimize the effort required by data owners while ensuring a unified format. It also provides a one-stop entry point for all available reconstructions, thus maximizing data visibility and impact.

Single Cell Portal (RRID:SCR_014816). The Single Cell Portal specializes in visualizing and disseminating single cell data. The Portal allows you to use natural language and faceted search to discover other scientists’ research and share your own findings. Each study includes information on cell types, singular or multiple gene expression, and spatial transcriptomics. In addition, interactive visualizations allow you to explore cell clusters and search for related genes. If you wish to explore further, you can download a study’s data. As a free and public resource, we strive to make open science interactive and powerful.

Anatomy and Morphology Molecular Portal (RRID:SCR_014816). The Anatomy and Morphology Project is a joint effort with the Brain Architecture Portal and the Single Cell Portal. Our goal is to visually combine anatomic and molecular brain data in. Users can search for neuroscience data using natural language and faceted search, and then this portal retrieves molecular data housed in the Single Cell Portal and anatomical data in the Brain Architecture Portal. Each study includes information on cell types, gene expression, related genes, and spatial transcriptomics. You can also download a study’s data to explore further and build on your science.
