487. Version 7.0 of ECCE out now

What's new:
1. There's a whole new type of calculation added, called 'Condensed Phase Reaction Study':

The previous reaction module has been renamed 'Gas Phase Reaction Study'. The real difference between the two types is that the Condensed Phase module uses the plan wave module in NWChem and thus uses explicit solvation, while the Gas Phase reaction module uses DFT/MP2. The latter can obviously use implicit solvation if requested.

2. The Def2-series of basis sets (Weigen and Alrichs, Phys. Chem. Chem. Phys, 2005, 7, 3297-3305) have been added to ECCE, and tools for adding basis sets on your own are now distributed with the ECCE sources. One of them is based on http://sourceforge.net/projects/nwbas2ecce/ , the scripts of which have been renamed gbsNWChemConverter and gsbDescriber. To add new basis sets, look at scripts/gbs.README in the ecce source directory, or in apps/scripts/gbs.REAME in the installation directory.

3. The precision of basis sets explicitly defined using coefficients and exponents has been greatly increased. Before, the energies obtained using the implicit nwchem basis sets and those obtained by defining the basis set through exponents and coefficients in the input could differ by 0.1 milli-Hartree in extreme cases. That should no longer be the case.

4. The COSMO parameter Rsolv can now be set in the Theory dialogue.

5. Other
There are other, non-obvious changes under the hood, such as an updated (2.2.25) apache httpd. The realease notes detail most of these.

Note that ECCE only runs on linux, and uses python 2.7. I haven't had much luck compiling it on Arch (due to python 3 seemingly being the default in Arch), but it runs fine on Debian Squeeze, Wheezy and Jessie, Fedora 18 and Scientific Linux 6.4 and Ubuntu something-or-other.


To install the binaries:

Note that there are only 64 bit binaries available. If you want to use ECCE on a 32 bit OS, you can, but you will have to compile the sources yourself. Luckily, this is very easy. Until I make a separate post, see here: http://verahill.blogspot.com.au/2013/01/325-compiling-ecce-64-on-debian-testing.html

To get the binaries (or sources) go to http://ecce.pnl.gov/using/download.shtml

Give your email and name so that the PNNL can track the number of users, as these things often impact on funding for different projects.

On the next page, select the version to download. Most likely you want the full binaries: install_ecce.v7.0.rhel5-gcc4.1.2-m64.csh

Download that file to e.g. ~/Downloads, and fire up your terminal -- in my case I'm doing an upgrade from a pre-release version of ECCE 7.0:
sudo apt-get install csh openjdk-7-jre
csh install_ecce.v7.0.rhel5-gcc4.1.2-m64.csh

You MUST perform the following steps in order to use ECCE !! -- Unless only the user 'verahill' will be running ECCE, start the ECCE server as 'verahill' with: /home/verahill/.ecce/e-v7.0b/server/ecce-admin/start_ecce_server -- To register machines to run computational codes, please see the installation and compute resource registration manuals at http://ecce.pnl.gov/using/installguide.shtml -- Before running ECCE each user must source an environment setup script. For csh/tcsh users add this to ~/.cshrc: if ( -e /home/verahill/.ecce/e-v7.0b/apps/scripts/runtime_setup ) then source /home/verahill/.ecce/e-v7.0b/apps/scripts/runtime_setup endif For sh/bash users, add this to ~/.profile or ~/.bashrc: if [ -e /home/verahill/.ecce/e-v7.0b/apps/scripts/runtime_setup.sh ]; then . /home/verahill/.ecce/e-v7.0b/apps/scripts/runtime_setup.sh fi ***************************************************************

Edit your ~/.bashrc and add the following lines (edited for your system):
export ECCE_HOME=/home/verahill/.ecce/ecce-v7.0b/apps alias stopecce='/home/verahill/.ecce/ecce-v7.0b/server/ecce-admin/stop_ecce_server' alias startecce='/home/verahill/.ecce/ecce-v7.0b/server/ecce-admin/start_ecce_server'
You can then start ecce by typing...ecce.

  1. No command 'ecce' found, did you mean:

    it dosen't work for me.
    I just sure I done until this level of installation:
    ECCE installation succeeded.

    I have problem for run!
    need your kindness and help
