Orthogonal cross sections can be visualized using the program 'vlv'. In contrast to 'vlview', 'vlv' accepts several data sets. However, 'vlv' does not visualize raw data or model functions. For such features, you have to use 'vlview' for individual subjects. As input, 'vlv' only accepts anatomical data and parametric maps (e.g. zmaps, tmaps, Fmaps, contrast images, ...).
'vlv' can be called using anatomical data sets and zmaps (or tmaps, or contrast images) in the following way:
vlv -in GV1T_t1_pl.v DD2T_t1_pl.v FF3T_t1_pl.v -zmap cgtbsGV1T.v cgtbsDD2T.v cgtbsFF3T.v
It is also possible to overlay several zmaps over the same anatomical data set, i.e., a norm brain. Then 'vlv' can be called as follows:
vlv -in norm_brain.v -zmap cgtbsGV1T.v cgtbsDD2T.v cgtbsFF3T.v
However, if more than 1 anatomical data set is specified by '-in', the number of anatomical data sets must coincide with the number of maps (specified with the option '-zmap').
