Error using cd Cannot CD to ...(Name is nonexistent or not a directory).

I have a script to load a file. It works well on another computer but on my laptop it gives me an error of: Error using cd Cannot CD to ... (Name is nonexistent or not adirectory).

The script is: pathname = '/LENOVO/Neolab/P5_260418/10sIllumination';

filelocation = fullfile(pathname,'*.swt');

files = dir(filelocation); cd(pathname);

data = zeros(4096,32,4,length(files));

for i = 1:length(files)

    [data(:,:,:,i),timestamp(i),ill_number(i),cycle(i),source(i),t] = SWTread_RJC_LAD(files(i).name);

end

[SortedIllum, SortedIndex] = sort(ill_number);

%Resort the variables data = data(:,:,:,SortedIndex); cycle = cycle(SortedIndex); ill_number = ill_number(SortedIndex); source = source(SortedIndex); timestamp = timestamp(SortedIndex);

Is there any solution?

"Name is nonexistent or not a directory"

Seems quite clear to me: you need to pass cd a path that actually exists.

Even better would be to avoid slow cd entirely, by passing absolute/relative filenames:

Get rid of the cd entirely:

D = '/LENOVO/Neolab/P5_260418/10sIllumination';
S = dir(fullfile(D,'*.swt'));
N = numel(S)
Z = zeros(4096,32,4,S);
for k = 1:N
    F = fullfile(D,S(k).name);
    [Z(:,:,:,k),timestamp(k),ill_number(k),cycle(k),source(k),t] = WTread_RJC_LAD(F);
end
