Hi,
I got group ICA components after group ICA, and got subject specific (individual) temporal information/spatial maps as following.

dr_stage1_subject00000.txt
dr_stage1_subject00001.txt
...

dr_stage2_ic0000.nii.gz
dr_stage2_ic0001.nii.gz
...


I put a design matrix for correlation with behavioral task when I perform dual regression.
I wonder output files (dr_stage 1, 2 files: individual temporal information/spatial maps) are pure individual data from dual regression, or it also contains information for correlation?
And what is the difference between dr_Stage2 files? (dr_stage2_ic0001, dr_stage2_subject00001_Z, dr_stage2_subject00001 )


Thanks,

YM Huh
