Hi,
I have a question regarding scaling in the preprocessing using AFNI proc.
When preprocessing a run with a resting-state script using the following blocks
-blocks despike tshift blur mask scale regress \
the .errts output file does not have a mean of 100 and it lacks the range from 0 to 200 (as the "scale" preprocessing block).
It seems that the .errts mean is 0, but how is the range defined?
Is the .errts still compareable across subjects, or do I have to again scale the preprocessed .errts output via 3dTnorm? I assume that running 3dTnorm on the errts is not advised, but I wanted to be 100% certain about this.
Thanks,
Philipp
