[Freesurfer] Longitudinal analysis with QDEC

Hello Dear FreeSurfer Developers,

Thank You once again for helping me a couple of months ago. Today I came across a new obstacle, as I have been trying to analyse longitudinal material. I have performed all preparation steps and I started performing statistical analysis in Qdec when receiving following message:

Error in Analyze: Couldn't open .../FreeSurfer_output/subjects/CT_10/BLD013_/surf/lh.thickness.fwhm15.fsaverage.mgz or .mgh file.

I have checked in the surface directory and I could not find this file. There were several variations of it, but not a file with this particular name.

I have been working with Freesurfer5.3.

Thank You for Your help! Pawel
