Hi Ben!

I started result viewer through 'wfu_pickatlas' command. I accessed pickatlas toolbox first, and then clicked the 'results' button right next to the 'analysis' button.
I also tried running result viewer through 'wfu_results_veiwer' command, as you mentioned, but same error messages were come up. I checked the wfu_pickatlas, wuf_tbx_common, and wfu_results are all included in MATLAB search path correctly.

Jiwon.
