Success!! Rick, I was able to generate the QC files by removing the "-radial_correlate yes" flag! Sorry- that was a stupid mistake. Thanks a lot!
Thanks for your suggestions, Paul. It does take a while for the admin folks to make cluster-wide changes to software versions, so installing these in my own path will make life much easier! I'll definitely do that.
Thanks again, for all your help! :)
