I want to combine two images, with the following characteristics:
A: r,c = 51200,38497 uint16
B: r,c = 41505,38497 uint16
into
C: r,c = 92705,38497 uint16
The problem is that when I am trying to save it is not possible due to the following error:
Images must contain fewer than 2^32 - 1 bytes of data.
In addition, a strange thing is that if it is not possible to write C as a tif in 16bits why it is possible to read an image with the similar rows and collumns of C matrix?
Any ideas about the saving step?

What code did you use to save?

How do you know it is? What code did you use to read?

yes,sir,may be use TIFF object,such as
t = Tiff('myfile.tif','w');
write(t,your_image_data);
close(t);

@Walter Roberson yes,sir,it is important on configure tiff writer,thanks
@zbingos may be use an example,such as
clc; clear all; close all;
% configure tiff
t = Tiff('myfile.tif','w8');
setTag(t,'ImageLength',10);
setTag(t,'ImageWidth',10);
setTag(t,'Photometric',Tiff.Photometric.RGB);
setTag(t,'PlanarConfiguration',Tiff.PlanarConfiguration.Chunky);
setTag(t,'BitsPerSample',16);
setTag(t,'SamplesPerPixel',3);
% make data
your_image_data = uint16(ones(10,10,3));
your_image_data(1,1,1:3) = 2^32 - 1;
% write data
write(t,your_image_data);
close(t);
% read and display
a = imread('myfile.tif');
a(1,1,1)
>> a(1,1,1)
ans =
uint16
65535

imread can read bigtiff. imwrite cannot write bigtiff. The link above shows how to write bigtiff.
