Hi, I am trying to set-up the output of model-free parameters as described earlier (https://mail.gna.org/public/relax-users/2009-02/msg00012.html), and I seem to run into the same issue as Prem (http://www.mail-archive.com/relax-users@xxxxxxx/msg00606.html). I have performed the update (http://www.mail-archive.com/relax-users@xxxxxxx/msg00608.html), but it did not fix it. Script 1: pipe.create('test', 'mf') results.read(file='tm1/results') value.display('S2') Relax output 1: pipe.create(pipe_name='my data', pipe_type='mf') Opening the file 'tm1/results.bz2' for reading. value.display(run='S2', param=None) RelaxError: The parameter argument None must be a string. Script 2: pipe.create('my data', 'mf') results.read(file='tm1/results') value.display(run='tm1', param='S2') Relax output 2: pipe.create(pipe_name='my data', pipe_type='mf') Opening the file 'tm1/results.bz2' for reading. value.display(run='tm1', param='S2') Traceback (most recent call last): File "relax", line 422, in <module> Relax() File "relax", line 131, in __init__ self.interpreter.run(self.script_file) File "/home/vvostri/Desktop/relax-1.3.3/prompt/interpreter.py", line 270, in run return run_script(intro=self.__intro_string, local=self.local, script_file=script_file, quit=self.__quit_flag, show_script=self.__show_script, raise_relax_error=self.__raise_relax_error) File "/home/vvostri/Desktop/relax-1.3.3/prompt/interpreter.py", line 531, in run_script return console.interact(intro, local, script_file, quit, show_script=show_script, raise_relax_error=raise_relax_error) File "/home/vvostri/Desktop/relax-1.3.3/prompt/interpreter.py", line 427, in interact_script execfile(script_file, local) File "model-free.py", line 94, in <module> value.display(run='tm1', param='S2') File "/home/vvostri/Desktop/relax-1.3.3/prompt/value.py", line 152, in display self.__relax__.generic.value.display(run=run, param=param) TypeError: display() got an unexpected keyword argument 'run' Thank you in advance!
