Re: Logic Expression in $DATA: ACCEPT or IGNORE
Hi Xinting,
You can separate the condition into several statements. For example, if you need to accept (A=1 OR A=2) AND B<100 you instead can have 2 or 3 IGNORE statements (depending on the values A can have), say
IGNORE=(B.GE.100) IGNORE=(A.GT.2) IGNORE=(A.LT.1)

Last I knew, it wasn’t possible to do an “AND” in an ignore statement (and checking the $data documentation in NONMEM 7.2, that still appears to be the case).
