Use the menu command View-Configure-Functional Overlay... to open the
Configure Functional Overlay dialog box. At the top of this are two
spinboxes to control the time point and condition (if available) for
your functional data. Don't forget to click the Apply button at the
button of the dialog after changing the time point.

Hi,
I am attempting to work with volume data for the first time and trying
to figure out how to control what temporal offset is shown in the
functional overlay. I checked the options, the wiki, etc, but didn't
find anything yet. That is most like because I'm looking at old data
that was generated in a way that is incompatible (it seems) with newer
versions, so I am sourcing stable2.
The command that originally generated the group comparison I am
viewing is
intergroupavg-sess -analysis EMerror -contrast ASevASc -group1
BwGroupNormalsError5 -group2 BwGroupAspError5 -intergroup
BwGroupError5 -space tal -spacedir tal
This is the path to the resulting group comparison
/space/balagula/8/users/EMexec/fMRI/GROUP_ANALYSIS/BwGroupError5/bold/EMerror/tal-rfx/ASevASc/
To view it I am running:
tkmedit-sess -analysis EMerror -contrast ASevASc -space tal -map
minsig -s BwGroupError5 -isxavg random -fthresh 1.3
My environment looks like:
FREESURFER_HOME /usr/local/freesurfer/stable2
FSFAST_HOME /usr/local/freesurfer/stable2/fsfast
SUBJECTS_DIR/space/ventzl/1/users/SUBJECTS_DIR

Thanks for any advice,
