How can I remove introns from a feature to obtain the cDNA sequence?
Select the Feature
In Map, Sequence, or Features view, click to select a feature that contains introns.
Splice to Remove Introns
To remove introns from the feature, click Features → Introns → Splice to Remove Introns... .
If desired, adjust the file name of the new sequence. To merge the segments from the original feature, click the check box. When you are ready to make the new file, click Splice.
View the Sequence
If the segments were merged, you will see a seamless spliced feature.
If the segments were not merged, the former intron boundaries will be visible as lines in Map or Sequence view.
