[Chimera-users] Smoothing and binning volume data

Not sure what you are asking.  You can do Gaussian filtering to smooth a map, or binning to average 2x2x2 voxels together producing a smaller smoother map using the Volume Filter tool.

To color “solid” style map rendering different colors at different data values click the nodes on the yellow line on the volume viewer histogram and then click the color button below the histogram to change the colors.
