Is it possible to filter the results of a differential search by a gene?

Or alternatively, is there a way to download all the results in a single file?

To the best of my knowledge you cannot do either of these things. The download the data button allows for downloading data for up to 2000 probes/genes at a time. If you’d like to retain the results of a differential search for all genes your best bet will be to download all the data and process it off line (e.g., using R or Python).

Thank you for the answer!

Yes, I downloaded all the data (2000 rows at a time) and processed them.

Thanks!

How did you download the data? I’ve been attempting to download it into an xml file. But when loading the xml file into excel it returns no data.

(Let’s resolve this on the other thread. This one relates to the Human Brain Atlas)
