Re: [PyMOL] Chain Selection doesn't work (MacPymolEdu)

[Sampson, J. <Jar...@ny...>]

Hi Simon -

It looks like your default Python is now 3.x rather than 2.x.  The built-in function reduce() was moved to functools.reduce() as of version 3.0.  You can confirm whether this is the case via “python --version” on the command line.

One solution might be to make 2.7 the default again, perhaps via symlink to /usr/bin/python2.7 or adjusting your $PATH, although honestly I'm not sure about which Python is actually used by the precompiled Edu binaries.  Maybe others can chime in on that.

Hope that helps.

Cheers,
Jared

Hi,
I'm trying to select specific chains with the following command, which used to work.

select xxxx, /3J3A//D

However, under Yosemite 10.10.2 (latest update), I keep receiving the following error msg and can't select chains anymore...very annoying...any ideas?

Traceback (most recent call last):
  File "/Users/Simon/Downloads/MacPyMOLEdu.app/pymol/modules/pymol/parser.py", line 254, in parse

    st = reduce(lambda x,y:x+"&"+y,lst)
AttributeError: 'module' object has no attribute 'reduce'

Thanks
