Dear SPMers
I got noises that show up outside of brain of SPM T-map using SPECT data.
I tried two methods.
First, I used relative masking with specific threshold value to remove it.
I applied several threshold vales but I can¡¯t see anything.
Second, I used explicit mask that is a standard one.
But I got message that is ¡° No inmask voxels-empty analysis¡±
What should I do to sort out this problem?
Any help will be appreciated.
Cheers
