Dear All, 

I am encountering an issue while running Tracula from the dmrirc file. An additional line was required to run smoothly, without errors. I added
" set usethalnuc = 0 " and it proceeded without errors, yet when " set usethalnuc = 1 " was added I encountered an error message. 

I might have missed some relevant information on the page, but could you please clarify what this setting does? Additionally, which preprocessing step might I have missed if Tracula only works with set usethalnuc = 0?

Thank you for your help in advance! 

Kind regards, 
Diana 

PS: I am also enclosing the test dmrirc file that I was using.
