Hi Mark,
We found the error, sorry! Checking the scripts, we accidentally switched the input file and the mask, arrghh.
Sorry for that!
Have a nice Sunday,
Heidi

Onderwerp: Re: [FSL] extracting individual values from seed-based resting state
Dear Heidi,
I'm not sure what "the values" are in this context.
Are you saying that these are z-statistic values? If so, then they are very low.
I think it would be helpful if you gave us more details about your "cluster, fslmaths and fslmeants" commands.
All the best,
Mark
