No, they are frames generated by projecting the average coordinates
along the specified eigenvector (see the manual entry for the 'modes'
command). You could potentially capture representative frames by
calculating projections along the desired eigenvector (or
eigenvectors) with the 'projection' action, then filtering frames that
match desired projection values (with e.g. the 'filter' action). Hope
this helps,
