Hi,
I tried to extract all local maxima from my activated cluster in a group contrast (T-test for positives, 1-sample t-test with 17 subjects; in SPM8). Below are my commands and results. However, results are empty. Why? Also, is it connect that I extract local maxima from con_0001.img ?
Thanks. Mike
<My commands>
mapparameters.image='con_0001.img';
mapparameters.UID='20170216';
mapparameters.out='test';
mapparameters.sign='pos';
mapparameters.thresh=0.0005;
mapparameters.type='T';
mapparameters.voxlimit=1000;
mapparameters.separation=8;
mapparameters.SPM=0;
mapparameters.conn=18;
mapparameters.cluster=2;
mapparameters.df1=16;
mapparameters.df2=[];
mapparameters.mask=[];
mapparameters.nearest=0;
mapparameters.label='aal_MNI_V4';
[voxels regions mapparameters UID]=peak_nii('con_0001.img',mapparameters)
<Results>
Using default option of whole brain for statistics, even if there is a mask.
Using the default of no RESELS. FWHM was incorrectly specified or missing.
Using the default corrected threshold of p<0.05.
Using the default option of not saving corrected output.
Threshold is:4.015
NO MAXIMA ABOVE 4.015.
