External Email - Use Caution

Dear Freesurfer experts,

I am trying to customize a colour map of my own, with five colours and scale from -12.5 to 12.5, since when using Heat (with default options), the scale is correct but it is shown in only four colours.

However after I created the .lut file (attached below), when loading it into freeview, the colour scale is from 0 to 6.

Does this mean I should also include scale information in the .lut file?

Any help would be much appreciated.
