Expected behavior:  
Actual behavior:  
I didn’t found the MS Lesion Simulator module in my 3D installed slicer. May be this is due to the slicer version. Could any one help me solving this issue please ?  
Thanks in advance.

Now, I installed the 3D Slicer 4.13.0- 2021. And I installed the MS Lesion simulator. However, I can’t enter the T1 volume in the input parameters…Only two choices: None and delete current volume as shown in the figure attached.  
how to manage this issue please ?

It sounds like you haven’t got any data loaded. I haven’t used this module but I assume you start by loading a volume.

Thank you Steve for your reply.  
I can’t load a T1 volume, It didn’t give me a hand to load the image. As I have told, there is only two choices in front of T1 volume: None and Delete current volume.
