I'm finally getting back to an RNAseq differential expression dataset I analyzed years ago and cannot remember what tool I used to generate these simple heat maps that I really like. I think it was an online interface where I could add/take away genes from the plot, alter comparison groups, pick options for significance symbols etc. It may have had the ability to filter by GO terms, or I may have used a different source (e.g., GSEA) to pick my genes and then just used this tool for the plots. I'm very rusty on this stuff and would be very grateful if someone can direct me back to this or a similar user-friendly tool. Thank you!
