External Email - Use Caution Hi Doug
I'm analyzing the gyrification values between schizophrenia and healthy volunteers. While performing group analysis in QDEC, I encountered an error when setting the smoothing (fwhm) parameter to 25. Here is the error message from the terminal output > fwhm.dat: 66.612034, rounded to 67 > ERROR: fwhm out-of-range (< 1 or > 30)! > Error in Monte Carlo simulation: Error running mri_surfcluster! The same error persists for all smoothing values i.e. 5,10,15,20,25. QDEC works when I set fwhm to zero units. Why it is like this? And what is the ideal value of smoothing kernel (fwhm) for gyrification analysis? With thanks Korann
