An advanced search on Cildb V3.0 is started by clicking on the‘Search’ button on the top row on the right. Then, it isnecessary to choose the species in which the proteome has to be searched for.The filter window then appears to adjust the filters in the left panel (nofilter means that the full proteome will be retrieved). Similarly, the outputwindow allows displaying particular properties (attributes) in columns for eachfiltered protein. A summary on the right reminds the user of all the filtersand attributes currently used. This also allows direct modification of theorders of the columns in the output by moving the attributes up and down in thelist. The last operation of the process is to show the results. The results aregiven by pages of 20 items with a maximum of 1000 items. To see all results,they have to be downloaded as a file. At any time, if the result output seemsincomplete or inappropriate, the filters and attributes can be modified byusing the ‘Back’ button (edit results) to refine the search andshow the results again. The quick search allows a rapid search by keywords. Theresult can be processed the same way as the one described above, with thepossibility to add attributes by ‘Edit results’ and to download thefile. Note the direct access to BLAST, Human genome Gbrowse, Motif search, Helpand access to older Versions of Cildb on the top row buttons to the right.
