Hello all,

I'm having the following problem using the local_time format with 3dDconvolve. For some subjects, some runs have zero events of a particular type. So, I am not sure how to code that when the times for different runs are in different rows.... Is there a special symbol to be used for rows that have no events of that type?

For example, if I have 3 runs, the usual local_time way of representing things is:
10 20 30 35
42
61 72 80
If runs 2 had zero events, what would I put on that line?

Also, some subjects have zero errors, and so there are zero events of that type. Are there any flags that would allow me to input empty event files (and the program would simply ignore them)? I'm trying to write a script that would work uniformly for all subjects...
Thanks much!
