Now, let's go to explore the database services, that is the forms in which the users can query the database about certain information. From the main menu, select the section 2 ACCESS THE DATABASE.

Now, you'll see a menu of five services that ABS offer in this first release. You can notice the availability of a specific help link below each option. If you have any doubt about the behaviour of every option, please consult this short handbooks:




According to the menu above, the following functions to access the collection of binding sites, promoters and genes are available in the first release of ABS:

1. Explore the catalogue of 650 real TFBSs annotated
   on the orthologous promoters of each gene.
   
   
2. Retrieve all of the binding motifs associated to
   a given TF, filtering by species.
   
   
3. Retrieve all of the promoter sequences in which
   at least one binding site for a given TF was annotated.
   
   
4. Construct artificial datasets based on the ABS annotated TFBSs.
   
   
5. Evaluate the accuracy of a set of predicted TFBSs using
   a list of known binding sites as a reference set.
