I have made a interface on GUI Matlab, now a have a button to open a .txt file. I need load into a text box, some data how coming from txt file. But my problem is that data are disposed in columns like this.
Vol AA MM DD hh mm ss
Vol AA MM DD hh mm ss
Vol AA MM DD hh mm ss
Vol AA MM DD hh mm ss
I have done this code: if true % code [filename pathname] = uigetfile({'*.txt'},'Open File'); fullpathname =strcat(pathname, filename); text= fileread(fullpathname); set(handles.pathy,'String',fullpathname); end

Hi,
I'm not entirely sure what you want to do, could you show what the text file looks like and what exactly you want to display in the text box

[filename, pathname] = uigetfile({'*.txt'},'Open File');
fullpathname = strcat(pathname, filename);
fileVars = dlmread(fullpathname,'',0,0);
displayVar = fileVars(1,3);
set(handles.pathy,'String',num2str(displayVar));
fill in the row and column you want on line 4

what do you want to display in the text box? Currently you're printing the path and file name, do you want to show all data lines in your file in the text box? If so, you want to replace set(handles.pathy,'String',fullpathname) with set(handles.pathy,'String',text)
