The expression landscape of 588 RNA-Seq brain tumor samples - of which 459 are fresh frozen and 129 are FFPE samples. These are displayed via a t-SNE plot generated using the St. Jude Cloud RNA-Seq Expression Classification analysis workflow. Diagnosis subtypes are denoted by color as per the legend (right). Specific samples, groups, or diagnoses can be highlighted by entering them in the search sample box. Pan and zoom functionality allow you to examine regions of the plot in more detail. Further details for each sample can be accessed by mousing over the dots and by accessing the associated metadata (https://platform.stjude.cloud/api/v1/manifest). These samples are available on St. Jude Cloud.
