Reading multiple image Tiff file

When I try to read a tiff image with imread I receive the warming:

" Only the first slice will be read from this image with depth 418 "

Which I understand. According to the documentation of imread, I schould then be able to acces the other slices by typig for example:

Image = imread(filename, 2).

However when I do that I get the message:

" Invalid TIFF image index 2 "

How can I read my entire tiff image (CT_Scan with 418 slices)?

imfinfo on this file returns the following information:

Found It! I used the function Tiff.

Unfortunately I have an extra dimension right now...

Hi Ingrid,

I'm having this same issue. What do you mean when you say you used the function Tiff? Are you using that instead of imfinfo? When I try:

tiffile = (Tiff(filename,2));

I get out:

Expected MODE to be one of these types:

char, string

Instead its type was double.

How did you end up making the multi-element struct for each TIF slice? Thanks!

@Noshin Nawar I think you're getting TIFF confused with read

The second argument to Tiff should be a letter. You probably want 'r' instead of 2.

Input Arguments

filename — Name of file

character vector | string scalar

mode — File access type

'r' (default) | 'w' | 'w8' | 'a' | 'r+'

Looks like it's not a multi-page TIFF, but a single page tiff with a 3-D volumetric image in it that has 418 slices. You can get the second slice (what you thought was a page) by indexing:

slice2 = image3D(:, :, 2);
