Hi,

I did not see this documented anywhere so I figured it would be best to double check.

Any group analysis relies on that the individual functional and structural data have first been aligned, and there is therefore a register.dat file in the individual subject's directory. This is usually saved at $STUDY_DIR/$SESSION_DIR/bold/register.dat

Now, when I run a group analysis, the functional (or structural) space of each individual subject is re-mapped onto the structural space of the target brain. This process must have access to the correct subject-specific register.dat files for each individual subject.

In the case of a spherical surface group analysis, I would do this re-mapping by func2sph-sess that I run inside the $STUDY_DIR. The command would have the format

func2sph-sess -analysis <analysisname> -sf sessid -df sesspar -trgsubject fsaverage -projfrac 0.3

where the contents of the "sessid" file would list all my $SESSION_DIRs (i.e., different subjects).

Question:

Where does func2sph-sess look for the individual level register.dat files? I assume it will automatically find them at $STUDY_DIR/$SESSION_DIR/bold/register.dat

Thanks,

Tommi
