Your are right, this may achieved by addition of a new column from the menu Data -> Add
Calculated Values. This equally extends the scope of an earlier question by you, too.[1]

Assuming you already have a table with the Lipinski criteria computed, you may then mark
the entries where simultaneously the molecular weight exceeds 500 g/mol and a number of
HAcceptors is greater than 10 by a test condition of

if(TotalMolweight > 500 && HAcceptors > 10, "reject", "admit")

index.php?t=getfile&id=226&private=0

And indeed, there are drugs which do not meet these screening criteria.

index.php?t=getfile&id=227&private=0

DW's manual describes in detail the syntax to apply here.[2] A minimal example .dwar
file is attached below, too.
