Dear All,
Would someone please help me?
I am very new to the SPM program and have a some questions. I am working
with spm8.
I am comparing the Brain SPECT with 3 kinds of filters (butterworth, metz &
wiener). I want to see which filter has best images in contrast or resolution
and has the best effects on Brain SPECT images. Please help me, How should I
design my study?
Is that correct that, I have 3 groups, 5 images that filtered with botterworth
for group 1, 5 images that filtered with metz for group 2, 5 images that filtered
with wiener for group 3?
I am using proportional scaling for this study. Is this the best choice or
ANCOVA is the best?
How can I define my "covariate" or every things for "design matrix" in this
case?
how should I specify my contrasts?
I am so thankful.
