The problem is
0(TAB)0 interpreted falsely as a dark red square although it should be a dark red square surrounded by zeroes/ones. Import has different data-formats such as Data and Matrix but I don't know which one this is: ASCII? So how can I import the below type data as a text-file to Mathematica and get the goal-style matrixplot? Is there some format command to specify the structure of the data for importing?
