How to customize a colour map so that all values of 0 are equal to gray

13 views (last 30 days)
Dear Matlab Community,
I am working with a nifti (.nii) image. I would like to plot the values I have using the 'jet' colormap.
With for example the 'jet' colormap, all values of 0 would have a green color. However, I would like to keep the jet colormap, but alter it so that all values of 0 instead show a gray color.
Can anyone please help as to how I can do this?
Thank you,
