Hi Tom, Maybe rather than saving the output of your python block to an external file you could save it into the Org-mode file, into a results block named e.g., "dot-temp", and then you could do the following in your sh code block... #+begin_src sh :var body=dot-temp echo $dot-temp > dot-temp.gv tred dot-temp.gv > test.gv dot -o test.pdf -Tpdf test.gv rm dot-temp.gv open test.pdf #+end_src Hope this helps -- Eric -- Eric Schulte http://cs.unm.edu/~eschulte/
