You probably won't hear from him since this was his only post and it was 4 years ago. To load images, use imread(). Also see The FAQ.

thanks for your answer, now I want to extract features from MR images, I have two questions 1- are there any ready code or toolbox for this purpose 2- which one features is better for segmentation? (texture, probability, histogram,intensity,...) thanks in advance

  1. I don't know of a toolbox that is specific to MRI images, though there is the general purpose Image Processing Toolbox.
  2. You should contact the radiologist that you are partnering with for the answer to this. You can also look at section 20 of VisionBib

Thanks for your help, but when using imread as follows : fin=imread('unc9.raw'); I get this error "Unable to determine the file format. " how can I solve this error?
