Hi Freesurfer expert,

I am having an error with the QDEC. I am using Freesurfer v6.0 stable and it keeps giving me error when I do the analyze. I can load the qdec table and all other commands still run fine but when I did the analyze, it gave this error. I have converted the license.txt to $FREESURFER_HOME/.license like previous suggestion but doesn't work.

Writing to /home/henrydo/subjects/qdec/Untitled/contrasts.sig.mgh -------------------------------------------------------------------------- ERROR: Invalid FreeSurfer license key found in license file /home/henrydo/software/freesurfer/.license If you are outside the NMR-Martinos Center, go to http://secure-web.cisco.com/1ZMUb3rLIKtbUCpTz2aOiKX5ZTHQDVKbpcuykvo5CNFCnYXL... to get a valid license file (it's free). If you are inside the NMR-Martinos Center, make sure to source the standard environment. --------------------------------------------------------------------------

I want to use QDEC to see which subjects will have impacts on different regions. If possible, I would like to have instruction how to do visualize it without qdec.

Many thanks, Henry
