Retrieve range of annotations from GFFAnnotation object
Range = getRange(AnnotObj)
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.
Object of the GFFAnnotation class.
1-by-2 numeric array specifying the minimum and maximum positions in the reference sequence covered by annotations in AnnotObj
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 = 3631 498516
