I had a working notebook with title and normal cells. I opened and
- all cells were merged to a normal (InputformDisplay type) cell, all titles and text cells are lost, that is, they became the same form as the equations.
- 'in' and 'out' appeared in the text (where I had the different cells) in the same form as the equation If I run the notebook, it gives error message, because it can't understand things that were previously titles. I could not save it with AuthorTools package, NotebookRestore.
It looks like this:
" Reversible Michaelis - Menten kinetics In[82] := parm = {parm1 -> 10, parm2 -> 1};
Plot[Evaluate[long expression here]]
Out[83] = p = 0.25 p = 0.75
"
