Isolating problematic items

One of the main functions of DET is the detection of questionable items. Once questionable items are detected, they can either be corrected or annotated on their questionability.

The DET offers multiple ways of finding questionable items. These are:

All these functions are only shown if you run the DET in full mode.

The item tree marks several items with different colours. Questionable items have their names drawn in yellow while extremely questionable ones are drawn in red.

A special tree view can also be activated from the the View -> problematic items menu. If this action is selected the tree is redrawn with all branches that contain questionable items expanded and all other branches collapsed.

In Bh and spd levels of the tree the middle tab is a table with all items contained in the respective branch. Questionable items are highlighted with yellow and extremely questionable with red background.

Finally in the root of the tree, the middle tab contains a table with all problematic items of the survey along with some view controls for further isolation.
