I have preprocessed an image which finaly gives angle values, since the image is in .img format. I have exported it to .tiff format and opened in Matlab. When i used imread function. The array is showing only 0 values, but image is in greyscale from white to black. secondly how can i get the angle values from the image.

how did you convert the .img to .tiff format?
What is class() of your input data? What is class() of the data you are writing? Are you possibly trying to write complex data?

basically it was in .img format. it has anlge values. This image consists only one band which consists angle values at each pixels. using imread sunction, the array is giving me 0 values, i have attached a file of it. since it has only one band, it has to show some values right. the whole 5463X2633 has values.
