Accidentally corrupted graphics (?) data of notebook --- now it won't open

In the process of editing my scripts' variable names with a haphazard "replace in all open files" in my text editor, I accidentally replaced portions of graphics data in a notebook (and I believe this is the only issue with the notebook). Here's a sample of my notebook in my text editor:

Cell[BoxData[
  Graphics3DBox[GraphicsComplex3DBox[$Failed, {{
   {Opacity[0.4], EdgeForm[None], 
     GraphicsGroup3DBox[{Polygon3DBox[CompressedData["
1:eJxNnXeYFcXz9e/esIiiIFGUKNw7d0Ewo0y4CIKKAdDdvYqKAQOKOWfFnHPO

4cx7TXSVD2Teu+MDFhwgfljAOT2aud6Wsf2U0A54IVLaBUP0ZtX22vhBf67Z

The \[CapitalOmega] doesn't belong. Unfortunately, "undo" is no longer available, and there's no obvious way for me to sift through and re-replace some of the symbols that I changed (for instance, they aren't all obvious like \[CapitalOmega]). Mathematica can no longer open the notebook (I wait while it grinds and heats-up, then have to force-quit).

Is there some way to delete the graphics (or even all output cells) from the text file? I was considering just trying this (deleting the cells that seem like graphics), but it seems like there might be a lot of ways this could go wrong. Help!

Answer

This should give you back most of your work:

code = Import[

   "https://bitbucket.org/ricopicone/corruptmathematicanotebook/raw/master/CMN.nb", 
   "NB"];
CreateDocument[
 code /. Cell[BoxData[(Graphics3DBox | GraphicsBox)[___]], ___] :> 
   Cell[TextData[
     StyleBox["Here was a graphics", FontColor -> RGBColor[1, 0, 0]]],
     "Text"]]

plotting - How to draw lines between specified dots on ListPlot?

I would like to create a plot where I have unconnected dots and some connected. So far, I have figured out how to draw the dots. My code is the following: ListPlot[{{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4,13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full] I have thought using ListLinePlot command, but I don't know how to specify to the command to draw only selected lines between the dots. Do have any suggestions/hints on how to do that? Thank you. Answer One possibility would be to use Epilog with Line : ListPlot[ {{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4, 13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full, Epilog -> { Line[ ...

equation solving - Invert and fit implicitly defined curve

I need to fit an implicitly defined curve. I thought I could get some data out of Solve , and then using FindFit . Therefore, I would like to find the relation the parametric curve defined by $F(x,y)=0$: Solve[-(1/2) + 1/2 (0.41202 BesselK[0, 0.1 Sqrt[x^2 + y^2]] + (0.101483 x BesselK[1, 0.1 Sqrt[x^2 + y^2]])/Sqrt[x^2 + y^2]) == 0, y] But I can't get an output: Solve was unable to solve the system with inexact coefficients or the system obtained by direct rationalization of inexact numbers present in the system. Since many of the methods used by Solve require exact input, providing Solve with an exact version of the system may help. >> Edit: In particular, I would like to fit the data coming from the curve with the expression of another curve, and not with a function $f(x)$. In particular, since this clearly looks like a cardioid , I would like it to fit to something like it. What other strategies could I try?

dynamic - How can I make a clickable ArrayPlot that returns input?

I would like to create a dynamic ArrayPlot so that the rectangles, when clicked, provide the input. Can I use ArrayPlot for this? Or is there something else I should have to use? Answer ArrayPlot is much more than just a simple array like Grid : it represents a ranged 2D dataset, and its visualization can be finetuned by options like DataReversed and DataRange . These features make it quite complicated to reproduce the same layout and order with Grid . Here I offer AnnotatedArrayPlot which comes in handy when your dataset is more than just a flat 2D array. The dynamic interface allows highlighting individual cells and possibly interacting with them. AnnotatedArrayPlot works the same way as ArrayPlot and accepts the same options plus Enabled , HighlightCoordinates , HighlightStyle and HighlightElementFunction . data = {{Missing["HasSomeMoreData"], GrayLevel[ 1], {RGBColor[0, 1, 1], RGBColor[0, 0, 1], GrayLevel[1]}, RGBColor[0, 1, 0]}, {GrayLevel[0], GrayLevel...
