I did the post-processing on brain images in 3D Slicer. I changed the color coding to display where MR signals values are higher or lower. I need to add the color bar onto the image in order to easily identify what “blue” or “red” color means. Please, in which program is it possible to change the color map and to add the color bar as well? I didn´t manage to do it in 3D Slicer.
Edit color table: Go to colors module, choose a color node that you would like to modify, click “Copy” button to create an editable copy (the default color nodes are read-only). If you choose a “color table” type of node (this is the most common) then you get hundreds of predefined colors and you can modify each by double-clicking the color swatch in the color column, which can be tedious if you want to make large changes. It may be more convenient to modify “Continuous” color node, such as “RedGreenBlue” because you can specify a few colors at arbitrary levels and the colors are interpolated between them.
Show scalar bar:
Slice views: go to DataProbe module, check “Enable slice view annotations”, check Scalar bar / Enable
3D views: go to Colors module, clone the color table that you use for the volume, set the same min/max range as you have set for your volume, and check Scalar bar / Display scalar bar
I´m working in the Slice view. In the colors module I set the color map and its range. In the colors module I check “Display Scalar bar” and the color range appears but in the 3D views. I would need to add the color scale to the slice views. How can I do it? Moreover, do I have to save separaetely the image and the color range or can one save the image and the color range at the same time?
