t values in the output of mediation_brain_results

[minakhosh]

Hi ,

I used mediation_brain_results for Fdr analysis, and I noticed that in the output I get a warning as:
'p-values in cl.Z will not give valid spm_max subclusters'.

t-values, and z values are also not reported for the peaks in the outputs of FDR, and only neg(logp) is reported as maxstats.

Does this warning implies that the neg(logp) reported as maxstats is not accurate?
Is the table reported with the coordinates of voxels that survive FDR, valid?

I also run the analysis with mediation_brain_results and cluster thresholding, and in the reports of clusters and subclusters, I have the t value, z value, and neglogp for all the peaks. I was just wondering if the t values reported for subclusters are accurate?

some of the peaks in FDR matches with the peaks in subclusters and they both have the same neg(logP), so I assume that in the table report
of subclusters, the neg(logP) is not accurate, as well.

Thanks for clarifying these few issues,

Mina
