Under Browse Mode
click on picture to enlarge the query assistant windows
In the opening screen of ChirBase Browser, you just click
on "Query Assistant" link and follow the instructions.
1. In Steps 1, 2 and 3 of the Query Assistant, specify the molecule roles and type of search for :
Step 1: Sample (solute)
Step 2: CSP (chiral stationary phase)
Step 3: Eluent (mobile phase solvents or modifiers)
To specify the type of search for a Sample, CSP or Solvent molecule, do one of the following:
To find separations with molecules that match your molecule structure exactly, click Exact structure.
To find separations with molecules that contain your structural fragment, click Substructure.
To find separations with molecules that are similar to your molecule, click Similarity.
To find separations with molecules that have your molecular formula, click Formula.
To find separations with molecules that have your molecule name, click Name.
Optional: To exclude the separations that use this molecule, set: Exclude from the results (NOT logic).
2. If needed, specify other data fields:
a. In Step 4 of the Query Assistant, click Select Fields.
b. Click a field name in the left box and then click Add.
To remove a field from your search, click the field in the right box, and then click Remove.
c. For each data field that you want to search, repeat Steps 2 and 3. You can specify a maximum of four data fields.
d. When you are finished, click OK. You see the fields in the Query Assistant.
e. Optional: To exclude the separations with the data that you will specify for this field, set: Exclude from the results (NOT logic).
3. Click OK. You see your customized Query Form.
Click the label at the top of a molecule box if you wish to change the molecule role and/or type of search
Enter a structure:
Double-click the Molecule box. You see ISIS/Draw
Draw a molecule, transfer your molecule structure to the Query form to see your molecule in the Molecule box.
For each field that you want to search, click the data value box below the field name.
Click a vocabulary term, if available. If you do not see a list of vocabulary terms, type a term directly in the text box.
4. When you are finished, click Search.
