How to deselect a selected row from tree selection?

Hi,

Is there a way to deselect a particular row from the tree selection?
I have a few selected rows in a table. But depending on an attribute of the selected row, I need to deselect it.

Example:
//All the selected rows are obtained in this these selections variable
var selections = tree.selModel.getSelections();

//The attribute "Should_not_be_Selected" represents the row which should be deselected.
for (var icount = 0; icount < selections.length; icount++) {
      if (selections[icount].data.Should_not_be_Selected === "yes") {

      //What should I do now with selections[icount] to deselect this row?

      }
}

I couldn't find any help with TableUtils or TreeHandler.

Any idea?

Thanks
