After a bad saving, I had problems with my Mathematica notebook. I have expressions in this form:
Cell[BoxData[
RowBox[{
RowBox[{"\[CapitalOmega]",
SuperscriptBox[
RowBox[{"(",
RowBox[{"B\[Beta]", "|", "B\[Alpha]"}], ")"}],
"B\[Beta]"]}], "=",
RowBox[{"{",
RowBox[{"0", ",",
RowBox[{"D", "[",
RowBox[{
RowBox[{"\[Beta]", "[", "t", "]"}], ",", "t"}],
"]"}], ",", "0"}],
"}"}]}]], "Input",
CellChangeTimes -> {{3.6538827264790764`*^9, 3.653882730240291*^9}, {
3.653882768458477*^9,
3.653882777822013*^9}, {3.653883018977806*^9,
3.653883022469006*^9},
3.653890453286024*^9, {3.6539033468457146`*^9,
3.653903357854344*^9}, {3.6539035195335913`*^9,
3.653903541642856*^9},
3.653903623781554*^9}]
How can I retrieve normal looking Mathematica input from this kind of code?
