Software
Release Notes
Installation
- First, before downloading the software, make sure you have "wish"
in your path. Type 'which wish' in a terminal window and it should come
back with a location
(eg, /usr/bin/wish). If you don't have it, you may need to install
tcl/tk on your machine first.
- Next, download the software from
www.bionmr.ualberta.ca/download/atom_comp
- untar it
> tar xvf atom_comp*.tar
- Copy the atom_comp script to a public place or your $HOME/bin directory.
> cd atom_comp/src/bin
> cp atom_comp /usr/local/bin
Example
- Make sure you have an ensemble pdb file. In this example we have 30
models. Use spaces or tabs to delimit the fields. Each line
contains one atom pair for comparison.
- Place protein atoms in a file

- Within a terminal window type "atom_comp". You should get the
following atom_comp gui. Next, enter your 3 input files and an output file.
- Click the "Read Data" button.
- Select the atoms to use in energy calculations.
Click the "Calculate" button.
- The output will look similar to this.
