The property editor allows to create or edit a Property or Condition (the same editor is used for both). The user should provide Name of the property, a short (but sufficient) description, and, that is also very important, select system of Units and the default Unit. The default unit will be used assumed for all records (i.e., you do not need to specify it) during the BATCH UPLOAD of molecules.
Here is a more detailed Instruction to create Property: LogPapp.
- Click new property in Properties Browser to open Property Editor.
- Provide name, e.g. logPapp
- Select Units system "speed" and select the required system of units, e.g. log(10^(-6) cm/s)
- Describe the property
- Save it
