How I can I resolve the errors of 1.'Port Width or Dimension' and,2. for DWT block 'number of rows in the input must be multiple of 2^(multiple of levels)' in DSP toolbox of Simulink,while I am doing wavlet decomposition?

Sir

I am facing a little error in my Simulink model of Islanding Detection (A Project of M.E.), in which I am processing Negative Sequence Current signal to DWT block of DSP toolbox to get d1 coefficients.The 2 errors are as follows:(I am using Frame Conversion block before Dwt block and output is fed to Time scope.)

1.Error in DWT block :The Number of rows in the input must be a multiple of 2^(number of levels).

2.Error in Frame Conversion Block: error in port width or dimensions. output port 1 of Frame Conversion is a 1×1 matrix.

Sir I have tried '1D to 2D conversion' block and 'convert ' block but the error persists.I am providing Negative sequence Current signals(output of 3 phase sequence analyzer) to the input of DWT block.

I will be highly grateful to you for the support. Thanks.
