Meta Index / Home Page / Description / Detailed layout of GUI / Column selection
Boolean columns cannot be used in the extraction of images, spectra/histograms,
and rate curves and, thus,
will not be shown with associated check buttons. To the right of
the pushable button with the name of the column are two
linked check buttons labeled ``true'' and ``false'' corresponding
to the two possible values. Only one value can be selected at a time
and pushing the column button shall append either of the sub-expression
colname==TRUE
colname==FALSE
to the global expression in the top
expression entry field.
