Dear Matt,
I looked at the input file you attached and had a few questions.
1) I noticed that you are using ttl signals. Are you sure that the decimal value of the computer port to which you are sending the signal is 888?
2) Trial giving each row a unique trial number; don't have a value of 3 for rows 4-103 of your input file.
3) What are the numbers in the last stim cell of rows 4-103? If those are the names of .bmp files, try naming them something with alphanumeric characters.
4) Are you attempting to use this input file and/or save your output files to a networked drive instead of the local drive of the computer with DirectRT?
