import 4x1 vectors from Inport block

Hi,

I want to import some data (100 numbers) from Workspace into a Simulink model with an Inport Block.

The data is generated as following:

test_data = [1:100]';
test_data_ts = timeseries(test_data);

test_data_ts is put into Configuration Parameters -> Input.

Another block is connected with the Inport block. This block requires 4x1 vectors at the input, so I put a Signal Specification Block between these blocks, with this configuration: Dimensions = [4 1].

Unfortunatly I get an error:

The external inputs specified for the block diagram indicate that the port dimensions should be [1]. Instead, the port dimensions are being set to [4x1].

Any ideas?
