How we did it
Figure 1A. The region in detail view, showing two protein coding transcripts in the Cat locus.
You should now see the new tracks on Region in detail:
Figure 2A. A marker and probeset are found in the 3' exon of the Cat-001 transcript.
Both the Marker track and the Illumina track show data at the end of the Cat transcripts. Remember, transcripts under the blue bar (contig track) are on the reverse strand of the genome, so the very left of the Cat transcripts is the 3' end, in this case.
You can zoom into the tracks further using your mouse to draw a box around the region of interest.
