Thanks newell. I actually figured this out by reading the help file (duh). However, since the program was originally written (by my former grad student) with files in lots of separate folders, I had to put all the files in one folder and am now in the process of manually changing all the paths. I don't think the experiment is written as succinctly as it could be- there are 64 different .que files that need to have path files changed (and each one has about 7 variables).
