How to Remove Invalid text characters from File names MATLAB

I have downloaded multiple .nc files to work with in Matlab however I belive the ncdisp function is not working to display the file as it has invalid characters in its name. My files names follow this pattern with only the first numbers changing(dates) :

20030301090000-JPL-L4_GHRSST-SSTfnd-MUR-GLOB-v02.0-fv04.1.nc

is there anyway I could go about changing the file name even just to 20030301090000.nc in matlab so I can change all my file names on a large scale.

My current attempts include using movefile , regexprep , and rename

Try this:

fileName = '20030301090000-JPL-L4_GHRSST-SSTfnd-MUR-GLOB-v02.0-fv04.1.nc';
[folder, baseFileNameNoExt, ext] = fileparts(fileName)

folder =

  0×0 empty char array

baseFileNameNoExt = '20030301090000-JPL-L4_GHRSST-SSTfnd-MUR-GLOB-v02.0-fv04.1'

ext = '.nc'

dashLocation = strfind(baseFileNameNoExt, '-');
if isempty(dashLocation)
    dashLocation = length(baseFileNameNoExt) + 1;
end
newBaseName = [baseFileNameNoExt(1:dashLocation(1) - 1), ext];
newFullFileName = fullfile(folder, newBaseName)

newFullFileName = '20030301090000.nc'
