Hello all,<br><br>I am converting one .mgz file to another like this:<br><br>mri_convert -i a.mgz -o conformed_a.mgz --conform<br><br>The data type of a.mgz is float. After the conversion, The conformed_a.mgz is uchar. However, I found that the places surrounding the brain which have 0 grayscale values in the a.mgz are having grayscale value 108 in the confored_a.mgz. <br>
This makes the conformed_a.mgz very whitish compared to the original one.<br><br>Is there a way to make the float 0 to a uchar 0?<br><br><br>Thanks.<br><br>Yang<br><br>
