Hello Freesurfer Gurus, I am trying to compute LGI analysis using Qdec and have successfully loaded my qdec.table.dat file as well as created .Qrecrc to include the new pial_lgi measure. However, when I try to analyze using this measure (or with any measure for that matter), an error pops up saying that it was not able to locate the fwhm10.fsaverage.mgh file. I am guessing that this is the smoothed file and therefore that I need to run recon-all -qcache -measure pial_lgi -average -s, but when I run this while in my subjects directory, it tells me the -average flag is unrecognized. (I also tried this with -fsaverage and got the same error). Can you please help troubleshoot what might be going on? The lh pial files have already been created. When those are created I am guessing the smoothed files aren't created automatically as well?

I was getting these instructions from the Schaer article here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3369773/#!po=31.2500

Thank you so much for your help! Claire
