Hi Torsten,

I'm having the same error message on a new Ubuntu 16.04 system. Fresh Fiji CMTK install. I tried installing dcmtk using the command you suggested. The install seemed to work, but I am still getting the same error message John mentioned above. You mentioned two other solutions: 1. A fix from the developers making the Fiji CMTK distribution. Who is this and how do I notify them of this issue? 2. building cmtk from source. I am not an experienced Linux user. Is there a step-by-step guide somewhere for how to do this?

Thanks
