Hi Image Analyst,
I am trying to implement rgb2gray as follows:
I=imread('Frame 0009.tif');
R=rgb2gray(I);
but after this it shows following error.
Error. This image is not RGB. Aborting.

When I run same function with same image on another machine it works properly.
Please tell me why it is happening.

Thanks in advance..
RK

Are you certain it is the same image? As in, did you try copying the image
from the non-working system to the other?

Are the Matlab versions the same on both machines? Which Matlab version are
you having trouble with?

The error message you indicate is not a possible error in the rgb2gray that is
part of 2008b.

On the machine that failes, check that you are using the correct version:
which rgb2gray

Show us what I is:
whos I

(ps: in general an exact copy paste of the error message helps)
