How to limit a string?

Hi,
I have some data that I am reading from a text file, and some of the data is PowerCylinderTemperatureHistogram and some is PowerCylinderTemperatureHistogramBreakpoints. Now when my code is filtering through the text, it associates the PowerCylinderTemperatureHistogramBreakpoints with PowerCylinderTemperatureHistogram, how can I limit that text that is chooses to JUST PowerCylinderTemperatureHistogram and not the Breakpoints?

fclose( fid );
rows = rows{:};

Test for the existence of the complete string and exclude...set those lines in the initial array =[] before processing the rest.
