Use this field to filter the coding potential of the target transcript. Transcripts were classified as coding or noncoding using a combination of CRITICA predictions and RefSeq annotations. Since coding and noncoding transcripts can overlap, it is possible for a single probe to target both coding and noncoding transcripts. To output probes that exclusively target noncoding transcripts, select "Noncoding Only". "Unknown" denotes target regions that do not have any associated full-length transcript and therefore have not been classified by the annotation pipeline. "Unmapped" indicates probes that could not be reliably mapped to the genome.
