Dear FreeSurfer Experts, I am running Qdec 1.4 and I want to extract raw data (in this case, volume) from the significant clusters after Monte-Carlo simulation. In this particular case, the summary file shows 5 significant clusters after correction:

However, when I run the command to extract the raw data from these clusters using this line: mri_segstats --i y.mgh --seg mc-z.abs.th13.sig.cluster.mgh --avgwf mc-z.abs.th13.cluster.ocn.dat --excludeid 0
The terminal window outputs this:

So I get a .dat file that only has 3 columns, which does not match up to the 5 that I originally observed after the correction. If you could let me know what the problem is that would be greatly appreciated.
Thank you.
