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
