read file from uigetfile routine

Hi, I am trying to load a file by using the uigetfile routine but my code seems to error out...

I get the following error

Error using readmatrix (line 157)

Unable to find or open 'file1'. Check the path and filename or file permissions.

[file1,path] = uigetfile('*.csv');
if isequal(file1,0)
    disp('User did not pick a file');
else
    disp(['Selected WRxx',fullfile(path,file1)]);
end
WRxx_0_00A = readmatrix('file1','Range','A3:D16003'); %replace file name

Don't use path for the name of your folder because path is a built-in variable name. Try this:

[baseFileName, folder] = uigetfile('*.csv');
if isequal(baseFileName, 0)
    disp('User did not pick a file');
    return;
end
fullFileName = fullfile(folder, baseFileName);
disp(['Selected WRxx ',fullFileName]);
WRxx_0_00A = readmatrix(fullFileName,'Range','A3:D16003'); % Load data into variable.

or better:

% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = pwd;  % or 'C:\wherever';
if ~isfolder(startingFolder)
    % If that folder doesn't exist, just start in the current folder.
    startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file');
if baseFileName == 0
    % User clicked the Cancel button.
    return;
end
fullFileName = fullfile(folder, baseFileName)
fprintf('Reading in "%s".\n', fullFileName)
WRxx_0_00A = readmatrix(fullFileName,'Range','A3:D16003');
