Hello, excuse me for posting this question one more time, may be one has time to give me a short answer, will be great help:
I am using randomise for VBM and used this command:
randomise -i GM_mod_merg_s3 -m GM_mask -o fslvbm -d design.mat -t design.con -T -X -c 2.3 -n 5000 -V
A- I used it to get TFCE, voxel-based and cluster-based analysis. Is this ok so?
B- How about -V, is this the smoothing-grade? Should i use for example 5 as a parameter, what happens if i write only -V without a value after it? If i dont want to use smoothing should i omit the -V?!
C- I have another clinical parameters and want to correlate them to the results of VBM. Should i put them in design-matrix as covariates and use this in Randomise?
D- If there are missing parameters in some subjects, is it valid to put zero as covariate for these subjects?
thank you very much for your help
