Hi all:
I'm performing the group analysis on my own data using command line on
FS5.1.0 and i'm a little confused about the Clusterwise Correction for Multiple
Comparisions. the command is as follows:
mri_glmfit-sim \
--glmdir lh.gender_age.glmdir \
--sim mc-z 10000 4 mc-z.negative \
--sim-sign neg --cwpvalthresh 0.05\
--overwrite
In this command, does the vertex-wise threshold (here, '4') mean that the
vertex whose p value is lower than 0.0001 can be considered to used for the
Correction for Multiple Comparisions ? likewise, does the sign (here,'neg')
mean that only negtive vertexs can be considered? Is there a criterion which
vertex-wise threshold and sign i should choose?
Hope you can give me some suggestions !_______________________________________________
