I have a matrix of expression data (rows -- genes, cols -- samples) that I want to view as a heatmap. It has row and column labels. And I want to be able to interactively sort the rows by expression in any one column (or alphabetically by column), or the columns by expression in any one row.
Basically, a paired down version of Excel, but with colours instead of numbers and a one-click sort interface.
Oh, one more thing, the matrix isn't that big -- maybe at most ~100 genes and ~50 samples and usually smaller.
Among the plethora of bioinformatics webservers and tools, there's got to be something that does this, any ideas?
Please don't answer "do it in MATLAB", or R, or whatever, I can do that but I want something with a bit less hassle -- ideally, I upload my tab-delimited textfile to some craftily designed website.
