Is there any way to check that my conclusions are right? (that my results are not significant enough)
thanks,

thanks for your quick reply.
is it possible that this is happening because i only have 5 controls and 5 patients (small population of 10 subjects)?

Dear everyone,
I am doing some stats with tbss and randomise and i did a TFCE-based testing in randomise. I can visualize differences in tbss_tstat1 in the colourmap (even when i display it in a 0,95:1 range).In the other hand, when i try to display the tbss_tfce_corrp_tstat1 (the corrected p value image) i can visualize differences, but when displaying with a 0.95:1 range nothing appears in fslview. does it mean that the results are not significant enough?
yes
can i display my results without the range? (is that correct)
not if you want to report that the results are statistically significant.
Cheers
thanks in advance,
