I have a question regarding how to use 3dttest or 3dttest++.
Each participant had a dataset with classification accuracy after I finished searchlight, but now I need to select voxels that their classification accuracy significantly higher than the chanve level (0.5) from every participant. I want to do the analysis of each participant, not a group analysis.
My script and Warning Message with 3dttest++:
3dttest++ -prefix FT_TF
++3dttest++: AFNI version=AFNI_18.3.15
++ -singletonA testing against fixed value=0.5
- ==> option -BminusA is automatically turned on
++ option -setB:: processing as SHORT from(all values are datasets)
** FATAL ERROR: option -set B(short form): need at least 2 datasets or sub-bricks.
or 3dttest -prefix FT_TF
** FATAL ERROR: option -set 2 doesn’t have eough datasets.
Thanks a lot in advance.
