Input Arguments

collapse all

Feature annotations, specified as a GTFAnnotation or GFFAnnotation object.

Output Arguments

collapse all

Minimum and maximum positions in the reference sequence covered by annotations in AnnotObj, returned as a 1-by-2 numeric array.

Tips

  • Use the getSubset method with the Reference name-value pair to return a GFFAnnotation object containing only one reference sequence. Then use this subsetted object as input to the getRange function.
