Re: ACCEPT question

Hi Jackie and Manisha, IF multiple conditions are specified in either the ACCEPT=(list) or IGNORE=(list) option on $DATA, they are connected by an implied ".OR." operator regardless of whether they are listed within parentheses with a comma between the conditions or in separate statements. So, the original specification Jackie gives below should, in fact, keep only those records where DVID=1 OR CYC=1, as intended. I suspect that the difference between what was expected and what actually happened has to do with either: (a) the presence of the IGNORE=# option or (b) the layout of the dataset. For case (a), the records with '#" in the first column will be excluded given the presence of the IGNORE=# option. In the sample you provided, they correspond with two of records where DVID=1 (which may have been counted in the records you expected to keep). For case (b), the '.' values in the sample dataset provided in the DV and MDV columns line up right next to the value in the column to the left without a space between and therefore, may not be being read as the next column as intended. This would result in all of the columns after the '.' being off by 1. For example, in row 2 of the sample dataset, it may be that NONMEM is reading DAY= 1., DV=0, TIME=3, and DVID=1. This would throw off your counts and can be confirmed by examining the FDATA file.

If you want to evaluate 'OR' instead, the only way I can think of is it give multiple ACCEPT commands. > > ACCEPT = (CYC.EQ.1) > ACCEPT = (DVID.EQ.1). > > This should include all those records where either condition is true. > > Cheers, > Manisha >
