geotiffread and plot example leads to errors

I am trying to follow this example:

https://www.mathworks.com/help/map/ref/geotiffread.html

with a GeoTIFF from:

https://neo.sci.gsfc.nasa.gov/view.php?datasetId=MODAL2_D_CLD_FR&date=2017-03-01

However, when I use this code:

[A, R] = geotiffread('MODAL2_D_CLD_FR_2017-01-01_rgb_3600x1800.tiff');

and then try to plot with:

mapshow(A, R)

I get a string of errors:

_Error using checkRefObj (line 25) Function mapshow expected input number 2, R, to be either a 3-by-2 referencing matrix or a scalar map raster reference object. Instead its size was 256x3.

Error in validateMapRasterData>parseImageInputs (line 112) refmat = checkRefObj(mapfcnname, R, size(A), R_position);

Error in validateMapRasterData>validateImageComponent (line 92) [A, R] = parseImageInputs(mapfcnname, dataArgs{:}, cmap, rules );

Error in validateMapRasterData (line 26) [Z, SpatialRef] = validateImageComponent(mapfcnname, ...

Error in maprastershow (line 127) validateMapRasterData('mapshow', dataArgs, displayType, HGpairs);

Error in mapshow (line 228) h = showFcn(varargin{:});_

Any thoughts?

Did you solve the problem?

I am facing same issue as after loading tiff file mapshow is showing following error.

Thanks in Advance

How are you downloading the GeoTIFF file from the below site?

https://neo.sci.gsfc.nasa.gov/view.php?datasetId=MODAL2_D_CLD_FR&date=2017-03-01

There are two types of tiffs, a floating point and a raster, on that site. I found out I need to load one for A and the other for R to get A in uint8 and R in the right format. Cumbersome, but now I got it to plot.
