Hi, I'd like to load my text file in to matlab using 'uigetfile' command. I can do that, but the problem is my text file must be in the same folder as my *.m file.
I'm writing the command something like below. And I'm getting an error at "Unable to open file." at the 'importdata' line (2nd command in my below code)
[STMFILE, PATHNAME] = uigetfile('*.TXT','PICK TEXT FILE');
[A] = importdata(STMFILE, '\t', 15);
Is there any way to load a file (eg:TXT) in to Matlab, which is not in the same folder/directory as my mfile?
Please help. Thanks

Hi,
when you want to read from another folder, you will have to use the full path:
[stmfile, stmpath] = uigetfile('*.txt', 'pick text file');
A = importdata(fullfile(stmpath, stmfile), '\t', 15);

@BSantos: choosing "path" as variable is more than dangerous, because path defines the MATLAB search path ...

Did you read the help text of uigetfile already?
help uigetfile
Especially the examples should be helpful. In opposite to this, the doc uigetfile is more helpful for the inputs, but not for the usage of the outputs.

Or you can change to the data directory before importing your data:
eval(['cd ',stmpath]);
A=importdata(stmfile,'\t',15);
