Retrieve range of annotations from GTFAnnotation object
Range = getRange(AnnotObj)
Use the GTFAnnotation.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 GTFAnnotation class.
1-by-2 numeric array specifying the minimum and maximum positions in the reference sequence covered by annotations in AnnotObj
Construct a GTFAnnotation object from a GTF-formatted file that is provided with Bioinformatics Toolbox™, and then return the range of the feature annotations:
% Construct a GTFAnnotation object from a GTF file GTFAnnotObj = GTFAnnotation('hum37_2_1M.gtf'); % Return first and last positions of reference associated with feature annotations range = getRange(GTFAnnotObj)
range = 41609 1371382
