[Homer-users] Homer II Questions

[Rachel Mulheren]

To clarify my second questions, I am also getting the same results when I
run an individual file and when I run a series of files as Group or
Session. Should the processed data be in the procResult.dcAvg portion of
the file for Group runs as well as individual runs? I noticed a Group
Results file that was created in the NIRs folder, but it seems to be an
empty Microsoft Access file. I also noticed no change in processed results
when I use the Group Average box in the main Homer II window, so I'm not
sure how this manipulates data (not menionted in the Homer II manual). If
there is no way to average across files, as I thought the Session and Group
options would, is there a way to combine .nirs data files?

Thanks for any input.
