Thank you again for your help, I very much appreciate it.

The information was both from the same computer. Could it be an issue with the layout of my data table? I tried including the table as a separate file now and am getting the following error (I have also copied the data table below the error message):

...
-gltCode 4 Session : -1*T1 1*T2 Anxiety : -dataTable @datatable.txt
Read 263 items
Error in if (len%%wd != 0) errex.AFNI(paste("The content under -dataTable is not rectangular !", :

In addition: Warning messages:

2: In scan(ff, what = "character", na.strings = "") :

3: In grep("[^\\\\]", opts) : input string 1 is invalid in this locale
Execution halted

Here is the data table:
