Nonnegative integer specifying the start of a range in each
reference sequence in AnnotObj. The integer StartPos must
be less than or equal to EndPos.
Nonnegative integer specifying the end of a range in each reference
sequence in AnnotObj. The integer EndPos must
be greater than or equal to StartPos.
Name-Value Pair Arguments
Specify optional comma-separated pairs of Name,Value arguments.
Name is the argument
name and Value is the corresponding
value. Name must appear
inside single quotes (' ').
You can specify several name and value pair
arguments in any order as Name1,Value1,...,NameN,ValueN.
String or cell array of strings specifying one or more reference
sequences in AnnotObj. Only indices of annotations
whose reference field matches one of the strings are included in Idx.
String or cell array of strings specifying one or more features
in AnnotObj. Only indices of annotations whose
feature field matches one of the strings are included in Idx.
Minimum number of base positions that an annotation must overlap
in the range, to have its index included in Idx.
This value can be any of the following:
'full' — An annotation must
be fully contained in the range to be included.
'start' — An annotation's
start position must lie within the range to be included.
Array of integers representing indices of elements in AnnotObj.
Retrieve Indices of Annotations from a GFFAnnotation Object
Construct a GFFAnnotation object using
a GFF-formatted file that is provided with Bioinformatics Toolbox™.
GFFAnnotObj = GFFAnnotation('tair8_1.gff');
Extract indices of annotations or features for positions 10,000
through 20,000 from the reference sequence.
