Hello
I am new to matlab. I am trying to load .dat files from another folder into matlab. I could use .txt files if that is easier.
Here is code I am using:
directory_name=uigetdir(pwd,'Select data directory');
directory_name=([directory_name '\']);
directory_name=uigetdir(pwd,'Select data directory');
directory_name=([directory_name '\'])
files=dir([directory_name,'*.dat'])
This opens the diretory and I am able to choose the folder of choice. However it does not load the file only the filename. In the matlab workspace it shows that file structure to be 1X1.
If I add the following lines:
filename=files.name;
data=load(filename);
I get the following error, of course:
Error using load
Unable to read file 15a001sen2.dat: No such file or
directory.
Please advise how to load files. thanks!

I already gave an example.
However, there is no standard format for .dat files. You need to know the format of the particular .dat files you are interesting in to know the commands needed to load in the data.

[filename directory_name] = uigetfile('*.dat', 'Select a file');
fullname = fullfile(directory_name, filename);
data = load(fullname);

fid = fopen([yourpath '/' 'file.txt']);
line1 = fgetl(fid);
res=line1;
while ischar(line1)
line1 = fgetl(fid);
res =char(res,line1)
end
fclose(fid);
res

Thank you for your response. Instead of the first line of code I added the following: [ afile workdir ] = uigetfile( '*.dat','Select DAT-file' ); fid = fopen([workdir,afile])and then the rest of the code, however when I use this code, it loads an array of 2501 X 9 instead of 2500 X 1.
