Hi Mrtrix3 community,
I recently ran a TFNBS analysis on my diffusion MRI tractography based connectome using connectomestats, and I would like to ask a few clarifying questions. I am trying to assess group differences between my two groups, each with 11 participants and I am expecting that there will be group differences. The following command is the one I used for my study:
**connectomestats connectome_mean_ST.txt tfnbs design.txt contrast.txt results_ST_group_diff -nshuffles 5000
**
From my understanding, the fwe_1mpvalue file contains edge-wise family-wise error (FWE)–corrected p-values, while the uncorrected_1mpvalue file contains the corresponding uncorrected p-values. Other files I got are abs_effects, beta_0, beta_1, enhanced, null_contributions, null_dist, std_dev, std_effect, tvalue, zstats.
When interpreting the values in the fwe_1mpvalue file, are edges with values below 0.05 considered statistically significant? Or should the values be interpreted as 1 - p value, such that values above 0.95 would be considered significant instead?
Thank you for your time,
Best,
Stephan
