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
