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["

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"]]

functions - Get leading series expansion term?

Given a function f[x] , I would like to have a function leadingSeries that returns just the leading term in the series around x=0 . For example: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x)] x and leadingSeries[(1/x + 2 + (1 - 1/x^3)/4)/(4 + x)] -(1/(16 x^3)) Is there such a function in Mathematica? Or maybe one can implement it efficiently? EDIT I finally went with the following implementation, based on Carl Woll 's answer: lds[ex_,x_]:=( (ex/.x->(x+O[x]^2))/.SeriesData[U_,Z_,L_List,Mi_,Ma_,De_]:>SeriesData[U,Z,{L[[1]]},Mi,Mi+1,De]//Quiet//Normal) The advantage is, that this one also properly works with functions whose leading term is a constant: lds[Exp[x],x] 1 Answer Update 1 Updated to eliminate SeriesData and to not return additional terms Perhaps you could use: leadingSeries[expr_, x_] := Normal[expr /. x->(x+O[x]^2) /. a_List :> Take[a, 1]] Then for your examples: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x), x] leadingSeries[Exp[x], x] leadingSeries[(1/x + 2 + (1 - 1/x...

How to thread a list

I have data in format data = {{a1, a2}, {b1, b2}, {c1, c2}, {d1, d2}} Tableform: I want to thread it to : tdata = {{{a1, b1}, {a2, b2}}, {{a1, c1}, {a2, c2}}, {{a1, d1}, {a2, d2}}} Tableform: And I would like to do better then pseudofunction[n_] := Transpose[{data2[[1]], data2[[n]]}]; SetAttributes[pseudofunction, Listable]; Range[2, 4] // pseudofunction Here is my benchmark data, where data3 is normal sample of real data. data3 = Drop[ExcelWorkBook[[Column1 ;; Column4]], None, 1]; data2 = {a #, b #, c #, d #} & /@ Range[1, 10^5]; data = RandomReal[{0, 1}, {10^6, 4}]; Here is my benchmark code kptnw[list_] := Transpose[{Table[First@#, {Length@# - 1}], Rest@#}, {3, 1, 2}] &@list kptnw2[list_] := Transpose[{ConstantArray[First@#, Length@# - 1], Rest@#}, {3, 1, 2}] &@list OleksandrR[list_] := Flatten[Outer[List, List@First[list], Rest[list], 1], {{2}, {1, 4}}] paradox2[list_] := Partition[Riffle[list[[1]], #], 2] & /@ Drop[list, 1] RM[list_] := FoldList[Transpose[{First@li...

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...
