You dont need pwd as a global.
Did you add the dicom libraries when you compiled your code?
if you think the filename is a problem - use fullfile, i.e:
[filename, pathname] = uigetfile ( '*.dcm', 'Choose DICOM file' )
% check that the user selected a file
if pathname ~= 0
filename = fullfile ( pathname, filename );*
info_FileName=dicominfo(FileName);
Pic=dicomread(info_FileName);
end
edit update the uigetfile command where originally the output arguments were typed the wrong way around - lesson for writing code and not testing....
