Parameters | Spectral Preprocessing | Filter to Include Observations

Filter to Include Observations
The Filter to Include Observations field is an optional parameter that enables you to subset an input data set. Only those observations that meet all of the conditions specified in the field are included in the analysis.
For example, to filter only probe set IDs less than or equal to β€œ1709_g_at”, you could use the following simple WHERE expression:
WHERE probe_set_id <= β€œ1709_g_at”
Note: the word where has already been entered for you.
For more information about using filter fields, see The SAS WHERE Expression.
