When you read in a sdf file with 3D coordinates you can view the molecule in 3D by one of two ways:
- right click on the 'mol' column in the table and choose 'Set 3D Browse Mode'
- a column labeled 'L' will be displayed which you can use to toggle the 3D display on and off.
- when toggled on the ligand will be displayed in the ICM
workspace left hand side panel
- you can select the ligand by double clicking on it.
Or
You can load the chemical into the ICM workspace by
- right click on 2D sketch of ligand in the table
- choose chemistry
- load and preserve coordinates.
