can’t find standard or standard.wts in weights folder (?)

[Anonymous]

Mac OS 10.7, 64 bit (i7 processor)
Python version 2.75 (version 3.4.1 also installed)

Hey, new to both PyRosetta, Python, and molecular modeling in general, but I found the PyRosetta User’s Guide and have been working through it-until I ran into an issue with the scoring functions.

It seems that the software cannot find the standard or the standard.wts file in the weights folder which is supposed to be used for creating scoring functions. Specifically, when I try the following sequence of commands:

-In [23]: name=’standard’

-In [24]: my_scorefxn=create_score_function(name)

I get the following error message:

ERROR: Unable to open weights/patch file. None of (./)standard or (./)standard.wts…exists

Did I install the software incorrectly? Or maybe there is a package or file I need to download for this to work?

Thanks to anyone who can offer advice or guidance, or if you’ve had similar problems please let me know how you were able to solve them-anything would help, I’m truly stuck here.

“standard” weights hasn’t been standard for a long time. About a year ago we switched over to the talaris2013 scorefunction as the recommended default, but even before then the recommended scorefunction was score12, rather than “standard”. To help reduce confusion, when we switched over to talaris2013.wts we renamed “standard.wts” to “pre_talaris_2013_standard.wts”.

So you can try using “talaris2013” as the name of your scorefunction, or better yet, just use the get_fa_scorefxn() function to get the current recommended default scorefunction for full atom purposes.

Thank you very much! No issues as of yet, but when I get stumped again I’ll make sure to come back to the forum.
