Hi,

I am looking at the experiments related to human(only human) present in ArrayExpress. I have used the following query for the same.

## To retrieve all the data sets studied in human
HS = queryAE(keywords = NULL, species = "homo+sapiens")

However, this query results in even the mixture of different species. Could you please advise on how to avoid this ? Also, is there any possibility to restrict the query to 'transcription profiling' experiments ?
