External Email - Use Caution        

Dear experts,

I used the function fspalm to run permutations with the following options:
fspalm --glmdir /my_glmdir/ --cft 1.3 --name palm --iters 10000 --cwp .05
--onetail

Checking the palmcofig.txt file that is generated as output, I realized
that even if the "–logp" flag wasn't specified in the function, this flag
is always applied with fspalm, and therefore the p-values of the
*dpv_tstat_uncp.mgz file are saved as -log10(p). Consequently, if I want to
threshold with p, I must first convert these values to p-values using 10^(-
p) and then use p<0.05.

In contrast, when I load the files *dpv _tstat_fwep.mgz and
*clustere_tstat_fwep.mgz, the results don't appear to be -log10(p), and
then these files wouldn't need to be transformed with 10^(- p) to use a
threshold of p<0.05.

What is the use of this flag in fspalm and why does it only affect the
uncorrected p values?

Thank you in advance.
Marina
