External Email - Use Caution

Hi Douglas,

I used to work with v5.3(centOS6) before and recently I changed a new computer, so I hope to keep using the same version(v5.3) in case of some version problem with old results. But I couldn't perform a qdec analysis because It kept giving me the invalid license key error when I press the analyze button. Owing to I am using different linux system(Ubuntu20), I install v6 to see if the error still exist. Qdec kept well during loading table file and generate stats file, but after I press the analyze button and it almost finished, the interface suddenly crashed and disappear as the content of terminal I have sent before. Wheareas, I used the mri_glmfit command in the terminal and it can work. That really confused me.

As to the license file, they have the same content as I have apply for license file three times after I downloaded different versions(v5.3,v6.0,v7.1). So I think using which one is OK maybe.

I'm not sure I understand. Are you using v6 qdec with a 5.3 license file?

Hi, dear Freesurfer experts,

I recently came across an invalid Freesurfer license key error while using v5.3, and I tried apply for another license key, it just sent me the same license key as I have apply before. Then I put the licence file to /usr/local/freesurfer and has changed the name to .license as well. But it still doesn't work. Owing to the version I used last time was v6.0, so I reinstall a v6.0 and use the same license file.

But here comes the new problem, when the analysis almost finished, qdec just crash and disappear, parts of the contents in the command window are:

I wonder what was the question? Appreciate for any suggestions.
