Does DAVID limit the maximum number of genes in a list?
The goal of DAVID’s design is to be able to efficiently annotate a list consisting of 3000 genes. Supported by advanced computing technolgies, all DAVID tools have been tested with 3000-gene goal and have shown to return results from a few seconds to no more than one minute. If running time longer than a minute, you should repeat you web call or check something else to make sure things right.
