TAB problem

[bb]

I like to avoid open strings, except for the lowest possible string, as
there is no alternative. Is it possible to raise an exception in
lilypond? How? Thanks.

Example:

check =\relative c {c8 e f gis a b }
\score {
  <<
    \new Staff { \check }
    \new TabStaff {      
            \set TabStaff.minimumFret = #4
            \set TabStaff.restrainOpenStrings = ##t
            \transpose c c,
            \check
    }
  >>
}
