I am working on uiconrol and I need to get the values from the slider so I can use it in onother script as a threshold to convert an image to a binary one. I have used n=get (s,'value') and n as a global var but it didn't work.
s =uicontrol('Style', 'slider','Min',0.01,'Max',1,'Value',0.01,'Position', [1030 420 90 20]);

Mayssa - how are you providing the value of the slider to the other script? Since you don't have a callback for the slider, at what point do you decide to pass this value on? Do you press a button or do something else? Please provide more details.

Why not just use GUIDE and put a slider, then in the callback, do this:
sliderValue = get(handles.slider1, 'Value');
Here's a nice framework you can get started with: http://www.mathworks.com/matlabcentral/fileexchange/24224-magic-matlab-generic-imaging-component

OK fine - you like to do things the hard way and build your GUI from scratch by specifying all the tedious details. But what about my suggestion to get the slider value? It will work regardless of how much work you put into creating your slider.
sliderValue = get(handleToYourSlider, 'Value');
