Attempted to access bwZ(3,2812); index out of bounds because size(bwZ)=[632,937,3].

this because bwZ is a 3d image does anyone know how to convert a 3d image to 2d image ?

I don't think your question is the one that should be asked. If your color image has 632 rows, and 937 columns, and three color channels (R, G, and B) or volumetric layers, then the real question that should be asked is "what were you thinking when you try to access the 2812th column in the 3rd row? And with no color channel specified."
