I am reading the multiband envi generated image file into matlab by using following matlab code;
img_path = 'C:\Image_Data\'
d = uigetdir(pwd, 'Select a folder');
imgfiles = dir(fullfile(d, '*.img'));
for m = 1:length(imgfiles)
img_file = imgfiles(m);
disp(img_file.name);
img = imread(img_file.name);
red = img(:,:,4); % red band
rededge1 = img(:,:,5); % rededge1 band
rededge2 = img(:,:,6); % rededge2 band
rededge3 = img(:,:,7); % rededge3 band
nir = img(:,:,8); % near infrared band
This is giving the following error
>> ds_indices_caf
img_path =
'C:\Image_Data\'
20240309_SAMPLE_DATA.img
Error using imread>get_full_filename
File "20240309_SAMPLE_DATA.img" does not exist.
Error in imread (line 372)
fullname = get_full_filename(filename);
Error in ds_indices_caf (line 17)
img = imread(img_file.name);

I am attaching the envi image file and request to kindly help me out to read the data from the image file.

I have kept matlab code and input data in same directory. Now following errors are coming;
>> ds_indices_caf
img_path = 'C:\Data\'
20240309_SAMPLE_DATA.img
Error using imread>get_format_info (line 554)
Unable to determine the file format.
Error in imread (line 395)
fmt_s = get_format_info(fullname);
Error in ds_indices_caf (line 17)
img = imread(img_file.name);
I would appreciate any help to fix it.
