Hi John,
Thanks so much. For the 4-8mm you suggested, do you mean the smoothing applied with FWHM or the effective smoothness in the data itself?
I have tried a 2mm kernel which gives an effective smoothness of 5.5mm in the data itself, and it seems to pick up quite a few reasonable regions. Would you suspect this to be valid?
Thanks so much for the prompt answers!
best,
Meng-chuan
