15.12.2 Molcart Getting Started

To start Molcart

Tools/Connect Molcart

Once you have activated MolCart the loaded databases and users will be shown in the ICM Workspace as shown below.

All the records and fields contained within each database can be viewed by expanding the tree structure in the ICM Workspace.

15.12.3 Molcart Search

How to search the databases contained within MolCart

Click on the button shown below.

To begin processing your query first you need to decide which database to search. The options are listed in the "Data Source" section of the ICM chemical search window.

You can either search a local table (molecular table) or you can search MolCart.

If you select MolCart you first need to setup the link to the correct database - described earlier. Click on the button shown above (yellow pencil) and the Connect to Molcart window will be displayed as shown below.

• Enter the Server Name in which the database is stored.
• Enter the database name.
• Enter your username and password for the server.
• You can save these details so you dont have to re-enter this information each time you use the chemical similarity search.

See the Chemical Search section of this manual on the many different search procedures.

How to perform a text search

To perform a text search on one of the databases contained within Molcart you first need to index the text within the database and then search using the query option.

To make the database index, see text and picture below:

• Expand the tree of the database in the ICM Workspace.
• Select the column headers you wish to search which contain Full Text or Partial Text(the data type for each column is listed next to the column name). Multiple column headers can be selected by clicking and holding down the CTRL key. A range of column headers can be selected by holding down the shift key and clicking to select.
• Next, right click and select Create Index.
• Select 'Full Text' and you will notice an additional header in the ICM Workspace called 'indices'. The value in the items category represents the number of columns you have chosen to text search.

To perform the text search:

• Right click on the database name in the ICM Workspace.
• Select 'Query' as shown below.

• Display results - displays your model in the 3D graphics window
• Minimize side chains - performs minimization on the side-chains
• Sample side chains - performs monte-carlo optimization on the side chains
• Write object to file - writes your new model as an ICM object

To build your model:

• Click OK

The ICM Chemical Search query window will be displayed as shown below. Type your query text in the space provided and hit the enter key or click on the search button.

How to add conditions to your query

• Right click in the box shown below and select 'Add Condition'. You can add as many conditions as you like.

• Double click in the fields labeled "Name" and "Relation" and select the options from the drop down arrow or type in values.

To remove a condition, right click on the filter and select 'Remove Filter'.
