Hi. I have a set of tiff images in an array (expressed as an array of double).

I want to save as a stack of images. I have tried:

for k=1:mx        
    imgArray2(:,:,k)=imgArray{k};       
end 
try   
 imwrite(imgArray2,sprintf('%s\\%s.stk',folder,prefix));   
catch
  h = errordlg('Error Saving Image STK')  
end

But get the error message:

Subscripted assignment dimension mismatch.

Error in myProgram>pushbutton53_Callback (line 4016)
    imgArray2(:,:,k)=imgArray{k};

When you say " I have a set of tiff images in an array (expressed as an array of double)." what is the "array"? Is it "imgArray", which is an array of cells, containing who-knows-what, or is it "imgArray2". If it's imgArray2, what is the class of that? uint8 or double?

Next, what is the value of mx and prefix?

These are the formats that imwrite() can write:

Where in there do you see the "stk" format? Because I'm not seeing it.

.stk appears to be Metamorph .stk files, which appear to be an extension of TIFF files. The contribution https://www.mathworks.com/matlabcentral/fileexchange/10298-tiffread2-m should be able to read .stk files. At the moment I do not know about writing .stk files.

Yes stk is from Metamorph. I dont need this format, just some way to collect a set of tiff images (which are doubles) and be able to save as a single file in any format. I would then later need to undo this and be able to eventually read the individual images.
