Good afternoon,

I have run into this same issue and am hoping someone may be able to resolve this question at this time.

I am trying to run 3dFWHMx on the residual time series (errts) from 3dDeconvolve. I am using a mask dataset created from 3dAutomask. The command I am using is as follows:

3dFWHMx –mask mask+orig –input residual_error.fit+orig –detrend –out ResidualError_fwhm.txt

If I remove -detrend then instead of -1's I get some 0's (not necessarily in the same rows as the -1's).

Also, I am very new to AFNI so please excuse the basic question but, it was my understanding that the output would contain a single row giving me the x, y, z blur, but I am given many rows; do I add a command to automatically generate the average across all rows, or is that something I do manually?

Thank you in advance!
