Hello Vittal,

Just FYI, the qdec program is deprecated in 7.X releases and is no longer maintained. In the 7.X releases, you can try using freeview for images and from the command line there are the mri* commands (mris_surf2surf, mri_glmfit, mri_glmfit-sim, etc.) for stream processing.

The license files from older versions of freesrufer, e.g., version 6, are not guaranteed to work on newer versions of linux OS’s because of changes to the crypt libraries. But a new license should work with a 7.X release.

Please in the future do not post any license files or content from them to the public mailing list. We can instruct you how to otherwise upload files for us to view.

- R.

Hi Vittal,

I tested your license file and it's fine. Are you sure it's in the right place? What's the output of `cat /usr/local/freesurfer/license.txt`?

It also looks like QDEC is trying to write to `/usr/local/freesurfer/subjects/qdec/Untitled/contrasts.sig.mgh` do you have permissions to write there? I'd suggest creating a FreeSurfer subjects directory under your home and setting the SUBJECTS_DIR environment variable accordingly, e.g.

mkdir ~/fs-subjects
export SUBJECTS_DIR="${HOME}/fs-subjects"

Hi Freesurfer experts,

I am trying to run Qdec on schizophrenia pre and post intervention scans.
I created .dat and .levels files within the qdec folders and loaded the .dat file into qdec gui.
It is suddenly crashing when I select my design and hit the Analyze button.
And the same error message copied below from the terminal.

Writing to /usr/local/freesurfer/subjects/qdec/Untitled/contrasts.sig.mgh

get a valid license file (it's free).
If you are inside the NMR-Martinos Center,
make sure to source the standard environment.

Even though I renewed my license file, the issue still persists.
FYI I did use qdec in the past and am quite comfortable with it.
Also, I attached my license file if anything is missing.

Any help would be appreciated!

With regards
Vittal
