How to read *.inp file and replace specific lines in the file

I have a *.inp file (Abaqus) with both characters and numbers, column # are not the same for all the lines. Just want to know how to read the file and change parts of data with my own data from another data file, and save it back to *.inp format. (Tried to open it as a cell-array file, replace some data and save it back as *.inp, but it does run on the Abaqus)

https://abaqus-docs.mit.edu/2017/English/SIMACAEMODRefMap/simamod-c-inputsyntax.htm gives the inp file format by the way.

My understanding is that you want to read a file and modify data. A workflow that I can suggest is to start with the import tool to interactively import variables (and generating a script if needed). Just ensure that "All files" is selected from the dropdown once (by default, it is "Recognized data files", the dialog to select the file opens. Refer to the following documentation for details. http://www.mathworks.com/help/matlab/ref/importtool-app.html

Once you have made changes to the variables, you can then use low level file I/O write back the data in the original format. http://www.mathworks.com/help/matlab/import_export/writing-to-text-data-files-with-low-level-io.html

I hope it helps.
