FIND (Fly in silico nanodissection) is a webserver for exploring the Drosophila embryonic development tissue-developmental stage-specific gene expression predictions. The predictions can be queried by genes (Genes Query or Genes Bulk Query) or by tissue-stages (Tissues query). The Similar Genes Query tool allows finding genes with similar spatiotemporal expression patterns. The Tissue Finder Query tool allows finding relevant tissues from ranked gene lists such as differential expression.
