ColorCells provides single cell transcriptomic analysis in 5 species including Human, Mouse, Zebrafish, Fruit fly and Yeast. You have ultiple choices on visualization of our datasets.
To browse the result tables, click Gallery in the top bar.
You can select data by Clade, Genome and Assembly. The result table will display the information of studies of the particular species, including its geoID, Series title, Pubmed id, Series statues, Source cell line and Tissues and more.
To view detailed information of these studies, click Details on the right.
To precisely access your prefer information, please click Search in the top bar.
You can search by Cell line or Tissue, Gene Name, Gene ID, GEO ID and Pubmed ID. (Please specific the Type before searching.) The results will be displayed in the same page. Click the geoID on the right for details.
We provide two dimensional reduction methods to display the cell clusters: Principal components analysis (PCA) (1) and T-distributed Stochastic Neighbor Embedding (t-SNE) algorithm (2). You can view them in both 2D and 3D.
