Do you check the contents of the resulting file by feeding it to another program? > 53, 0.170973146505, 0.0466686190136 > 57, 0.231749688431, 0.0405121944142 > t60, 0.250420691759, 0.0399644155193 > 58, 0.234883810317, 0.0488399925217 > 61, 0.2666025, 0.03541845 There's a "t" at the start of the line after the last line you claim to see, so maybe your input file is corrupt and your reader stumbles over that line.
