Clearly Main must be something other than a 3D array at this time or you've aliased size or somesuch.
What does
whos Main
return? If that doesn't clarify things, then
which size
clear size
and try again.

In addition to dpb's suggestions, which will probably fix it. You got the names wrong. The first dimension returned by size() is the y dimension (rows), not the x dimension. Thinking that the order x,y is the same as row,column is a very common error. So use one of these calls
[rows, columns, numberOfColorChannels] = size(yourImage);
[ySize, xSize, zSize] = size(yourImage);
but NOT the way you did it.

Good catch, didn't even notice that--dpb

Maybe a bit pedantic, but it all depends on your coordinate system. The OP could very well have a coordinate system where x is pointing down and y pointing right.
Probably not.
It's actually a bit of an issue that matlab's documentation (particularly regionprops) doesn't actually specify which coordinate system is in use.
