Dear FSL experts,

After 5000 permutations I thought I got some significant results (p < 0.05, TFCE corrected) when I checked them in FSLview. However, when I want to extract the cluster information, I get some inexistent coordinates and there are not  1-p values. The script that I am using is:

cluster -i PDL0_tfce_corrp_tstat1.nii.gz -t 0.95 --scalarname="1-p" > PDL0_visual_neg.txt 

Can it be that the Fslview results (even when the threshold is set at p < 0.001) are not completely true? I am asking this because I got another significant results that are visible at a very low threshold in Fslview but do not appear in the correspondent cluster information extraction.

I would really appreciate any help or advice.

Regards
