How to collect the complex data of a dpsk modulator in a text file

I am experimenting with the one of the flowgraph examples
“uhd_tx_dpsk.grc”. I am able to see the complex number output in WX GUI
NUMBER SINK block but I want to collect this output in a text file. If I
use a “FILE SINK” block, it shows some symbols but nothing in the form
of
x+jy. Kindly suggest some technique to do this.

You need to use Matlab/Octave to read these files.
