My input file does not write data to an output file. It creates the log file but when you open it there are headers but empty columns.

I'm guessing it's probably because your input file has all 0's for block values.
Check this out from the user's guide:
Block
QuickInfo
A label to help you keep track of which trials are which. DirectRT for the most part does not use this number but does write the assigned value to the data file for your reference.
Value
Any Integer. A "0" specifies the trial data is not to be written. By default, only trials on which data are collected will be written. A negative block ID (e.g., -1) will force DirectRT to write data even if no response is collected (e.g., display-only trials).
Details
If you are repeating sets of trials within a single input file, you may wish to label each trial with the set to which it belongs. You may use any integer value for any trial. Using the value of "0" will indicate that the data obtained for that trial is not to be written (e.g., in the case of instruction or debriefing screens).
Hints
You may be including a series of instruction screen or "rest" trials in your session. If you do not want these trials to clutter up your data files then assign them a Block value of 0. Data will not be recorded for any trial with a block value of 0.
