This error message appears if you click the Find Requests button on the Track Microarray Hybridization Requests window or the Find Results button on the Fetch Microarray Hybridization Results window without having entered any search criteria into the fields at the top of that window. You must enter at least one search criterion. You cannot simply click the button hoping that all of the requests/results you have access to will appear in the results grid. Click OK to clear the error message. Then, enter at least one search criterion on the window before initiating the search again.

Note: This error will also appear if you click on the Fetch Results (for selected experiments) hyperlink on the Track Microarray Hybridization Requests window but have not selected any experiments in the results grid on that window to transfer to the Fetch Microarray Hybridization Results window. In this case, the Fetch Microarray Hybridization Results window will have opened, but because you did not select any experiments to transfer and GNomEx is actually trying to perform another search with criteria based on the experiments you were to have selected, the error is the result.
