I'm using DAVID tool online, in order to perform functional annotation chart. I extracted the most relevant genes from a dataset (GSE73304), but have the problem that DAVID is not able to understand the most part.

I tried to put my 250 most relevant genes, such as


into David, using as identifier "AGILENT_ID", as I found in the website. However, David is able to recognize just 89 of them (which are classified correctly as "homo sapiens"). I have the same problem if I try to do the gene_id conversion.

This might be not a David's problem, since I tried also on R withoud good results.

If someone knows the reason of this issue and how to solve it, it would be really appreciated

Thanks in advance

  • $\begingroup$ First try converting your Agilent probe IDs to Entrez ID or Gene Symbols and then run functional annotation analysis. You also need to understand that Gene Symbols or Entrez IDs are not available for all probe IDs. $\endgroup$ Sep 11, 2023 at 8:44
