Issue on Reading .txt file from Automatic Test Equipment (ATE)

Hi,

I'm trying to read some ATE .txt file to do some Analysis using appdesigner. The data looks like this (attached):

I tried readtable/readvars/textscan/uiimport, with the delimiter as ' ' or '\t',such as:

 Data=readvars(str, "Delimiter",' ','EmptyLineRule','read','ConsecutiveDelimitersRule','join');

But none of them work well. The most likely result is :

which is apparently unanalyzable and frustrating.

Any solution or any idea about this will be appreciated!
