1. When I download a 3D .mhd gray scale image with ParaView 3.2.1, it<br>
appears in colour. The option "Map Scalars" under Display option can be<br>
turned off with a .png image to have a grayscale one but this option<br>
does not work (i.e. remains inactive) with the .mhd image. How can I<br>
view my image in gray scale?<br></blockquote></div>"Map Scalars" option is enabled only when the array used to color is made up of upto 4 component unsigned chars. You can look at the data type/number of components for the arrays using the "Information" tab. To map scalars using a grayscale lookup table, go to the "Display" tab, click on "Edit Color Map", then click on "Choose Preset" and select grayscale.<br>
