Now I am using hypercube function as follows
img = hypercube(img_file.name);
red = img(:,:,2); % red band
rededge1 = img(:,:,3); % rededge1 band
rededge2 = img(:,:,4); % rededge2 band
rededge3 = img(:,:,5); % rededge3 band
nir = img(:,:,6); % near infrared band
it still gives following errors.
>> ds_indices_caf
img_path = 'C:\Data\'
20240129_MAWANA_SUBSET.img
hypercube with properties:
DataCube: "[3915x3677x7 uint16]"
Wavelength: [7×1 double]
Metadata: [1×1 struct]
Index in position 3 exceeds array bounds. Index must not exceed 1.
Error in ds_indices_caf (line 25)
red = img(:,:,2); % red band
I would really appreciate the kind cooperation in helping me out to fix this error.

Here the variable "img" is hypercube object. The data is present in DataCube property.
Access the data using this command: red = img.DataCube(:,:,2);
