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 FUNCTIONALS_DIR /usr/local/freesurfer/stable2/sessions MINC_BIN_DIR /usr/pubsw/packages/mni/current/bin MINC_LIB_DIR /usr/pubsw/packages/mni/current/lib PERL5LIB /usr/pubsw/packages/mni/current/lib/perl5/5.8.5 GSL_DIR /usr/pubsw/packages/gsl/current QTDIR /usr/pubsw/packages/qt/current TCLLIBPATH /usr/local/freesurfer/stable2/lib/tcltktixblt/lib FSL_DIR /usr/pubsw/packages/fsl/current
Thanks for any advice, Rob
