MATLAB: Port Size on a Bus Selector block

bus selector blocksimulink

I am using a Bus Selector Block to pick a particular signal object from a bus. I get the following error:
Error in port widths or dimensions. Output port 1 of 'SimulinkModelName/MATLAB Function Block' is a [55x1] matrix.
Error in port widths or dimensions. Input port 1 of 'SimulinkModelName/Bus Selector' is a one dimensional vector with 1 elements.
The MATLAB Function Block is where the bus signal is coming from and goes into the Bus Selector.
How can I get the Bus Selector inlet port dimensions to match the MATLAB Function Block outlet port dimensions?

Thanks Kaustubha,
I had the output over-defined. Removing the size and leaving the bus object assignment fixed the problem.
