Hi guys,
I am currently trying to convert a .mat file to .tif. The background is I ran a script that produced a .mat file that is a super-resolved microscopy image. I have taken a look at https://www.mathworks.com/matlabcentral/answers/312269-how-to-convert-mat-file-to-tif-file. However, I am not sure about the parameter about xmin, xmax, ymin, and ymax. Any help is appreciated. Thanks in advance!

You need not to convert it into .tif to see the image.....you can see the image with the data itself...have a look on imshow, imagesc, pcolor etc functions.

If the data is integer valued, you would typically use imwrite() to create the tiff, unless there were special needs.
If the data is double precision or single precision, and you need the tiff to be the same precision, then there is a File Exchange contribution for writing floating point tiff files.

Hi Mario,
I have gone through your question, and I assume you might need some info about how to convert your “.mat” input file into “.tif” image, along with that ,I understand that you also have some query about range parameters which are involved in this conversion of. mat to .tif(xmin, xmax, ymin, and ymax).
The parameters “xmin”, “xmax”, “ymin”, and “ymax” are likely referring to the spatial extents of the data within the .mat file that you want to convert to a “.tif” file. These parameters are used to define a region of interest (ROI) or a bounding box within the image, which can be useful if you only want to convert a specific part of the image rather than the whole thing.
In the context of converting a .mat file to a .tif file, you might not need to worry about these parameters if you want to convert the entire image. If the .mat file contains a single variable that represents the image data in its entirety, you can simply read this variable and save it as a .tif file using MATLAB functions which basically involved “load”,”image_data” followed by “imwrite”.
Here's a basic example of how you might convert a .mat file to a .tif file in MATLAB:
% Load the .mat file
data = load('sample_image.mat').
% Assuming 'image_data' is the variable name of the image in your .mat file
% Define the region of interest (ROI)
xmin = 100; % The minimum x-coordinate of the ROI
xmax = 200; % The maximum x-coordinate of the ROI
ymin = 50; % The minimum y-coordinate of the ROI
ymax = 150; % The maximum y-coordinate of the ROI
% Extract the ROI from the image data
roi = image_data(ymin:ymax, xmin:xmax);
% Save the ROI as a .tif file
imwrite (roi, 'your_image_roi.tif');
You can refer to following documents for more information regarding Image Conversion Operations.
Hope this helps!
