Class: GFFAnnotation

Retrieve range of annotations from GFFAnnotation object

Syntax

Range = getRange(AnnotObj)

Description

Range = getRange(AnnotObj) returns Range, a 1-by-2 numeric array specifying the minimum and maximum positions in the reference sequence covered by annotations in AnnotObj.

Tips

  • Use the GFFAnnotation.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 method.

Input Arguments

AnnotObj

Object of the GFFAnnotation class.

Output Arguments

Range

1-by-2 numeric array specifying the minimum and maximum positions in the reference sequence covered by annotations in AnnotObj

Examples

Construct a GFFAnnotation object from a GFF-formatted file that is provided with Bioinformatics Toolbox™, and then return the range of the feature annotations:

% Construct a GFFAnnotation object from a GFF file
GFFAnnotObj = GFFAnnotation('tair8_1.gff');
% Return first and last positions of reference associated with feature annotations
range = getRange(GFFAnnotObj)
range =
