NiiStat and MRIcron (NPM)
Dear all,

I have some questions about NiiStat - MRIcron (NPM).
- If you want a continuous analysis with two predictors (behavioral data) and lesions ROIs, it's recommended to use NiiStat with Freedman-Lane permutation. In addition if you do a two-way analysis you set up "SVM" in the "Special" option.
If this is correct, your output will be "r" number and "r ^ 2" number, with also the p significance number. Which Z-number do you put on MRIcron for see your results (significant voxels correlates at two behavioral data)?

- only one confirmation: also in the NiiStat like NPM (by MRIcron) in the analysis you use the correct answers of behavioral data. But in NiiStat you look only the negatives numbers.

- I found it better to use the Classic NiiStatGUI. In case in MATLAB command line how do you set the "Special" options (e.g. SVM)?
e.g. NiiStat ('name.xlsx', 0,1, -8000,0.05,10, ... and then for SVM setting?)

- In cases with lesions files and 1 set of continuous behavioral data, is the voxelwise analysis with NiiStat (with Normal Permutation, voxels analysis, lesion modality) comparable / like NPM analysis?


Thank you for your help, best regards
