Hi everybody,
I am clustering a jaccard index based distance matrix, using clustergram. The distances are between 0 and 1. Although the option DisplayRangeValue of clustergram takes one value and sets the color map between [-value,value],in other words if it is set to 1 the range will be [-1,1]. e.g. CGobj = clustergram(Data, ...'DisplayRange', DisplayRangeValue, ...) Are you aware of way to set an assymetric range, like [0,1]? Thanks for your help.

Hi Marouen Ben Guebila,
Unfortunately, the ability to change the display range for the colour scale directly is not available for the CLUSTERGRAM function in the Bioinformatics Toolbox.
As a workaround, create a plot with the CLUSTERGRAM in it, and then set CLIM property.
>>cg = clustergram(...); % Create the clustergram object
>>cgAxes =plot(cg); % Use the plot function to plot to a separate figure and output the axes
>>set(cgAxes, 'Clim', [80,90]) % Set colour limit or other axes properties.
>>colormap hot; %You can also change the colormap if you want
Hope this helps!
Thanks
