Hi Jason,
So once I've created the environment py27 with conda, how do I use it with Amber?
I don't have access to my workstation right now, but should it be something like
./configure --with-python py27
make install
I prefer to do that rather than forcing it to use Python 3, as I would like to make full use of the AmberTools programs.
Thanks for the info,
Juan

Most of Amber's Python tools are written for Python 2. Some of them are
Python-3 compatible (I know ParmEd can be installed with Python 3, and I
*think* MMPBSA.py will work as well), but others are probably not.
So the configure script looks for python2.7, python2.6, python2.5,
python2.4, and falls back to python if none of the previous choices are
available. You can always use conda to set up a new Python 2.7 virtual
environment:
conda create -n py27 python=2.7
And use that environment with Amber.
If you want to force AmberTools to use your anaconda Python 3, you can use
"--with-python `which python`" when you run configure.

conda should come with Tkinter already installed.
