Hello TBSS experts,
I have a question concerning how valid it is to present raw test statistics.
After running randomise I get the three following thresholding/output options:
a) _tfce_corrp_tstat (FWE - TFCE corrected for multiple comparisons)
b)_tfce_p_tstat (TFCE - uncorrected for multiple comparisons)
c)_tfce_tstat (TFCE - raw test statistic)
In the literature, it is common that both corrected and uncorrected TBSS results (voxel-wise and TFCE) are presented with the latter validation of an application of a ROI analysis, in the regions identified as having statistically significant differences.
So my question is, can one present these _tfce_tstat (TFCE - raw test statistic) results and use a ROI analysis to back them up or is this inappropriate?
Additionally, could someone please point me in the right direction as where to read up on these "raw test statistics" because I can't find any information in the archives or in the randomise manual.
Thank you for your insight and help,
