This page is intended to be an index of useful info concerning group practice and use of software including tutorials. Please feel free to add any notes you have on software use and especially on common problems you encounter. Any links in red have not been written yet so if you get time, please fill in some of the gaps!
Group software
Our software is managed under Subversion (SVN) version control. For information on how to set up your SVN details and access the code, see the SVN setup page. Tips on good practice when using SVN can be found on the group version control page. It is highly recommended that you read this once you have set up your details. Once you're up and running, you should definitely take a look at the Theory Sector SVN Page which is chock full of useful info on the commands you'll be using on a regular basis.
The official documentation can be found here. It is highly recommended that before you start any jobs, you check the documentation to make sure you understand what each keyword you have specified does and if it's necessary! The links below provide a few working examples for each program the group uses, from initial setup to job submission.
Showing your output to DJW is particularly important when you are starting to use one of these programs for the first time. Always question any output that looks suspicious. The below links provide more information on each piece of code, including worked tutorials and general help!
- GMIN: A program for finding global minima and calculating thermodynamic properties from basin-sampling.
- OPTIM: A program for optimizing geometries and calculating reaction pathways
- PATHSAMPLE: A driver for OPTIM to create stationary point databases using discrete path sampling and perform kinetic analysis
Useful software
- CHARMM
- AMBER
- REX (Replica EXchange MD) with the MMTSB-toolset
- gnuplot
- VMD
- Pymol
- xmgrace
- xfig
- disconnectionDPS
Useful scripts
- perm-prmtop.py: A python program that converts an AMBER9 topology file into one with a symmetrised potential with respect to exchange.
- perm-pdb.py: A python program that creates a perm.allow file for use with OPTIM and PATHSAMPLE.
- path2pdb.py: A python program to convert path.info to path_all.pdb - you can easy visualize your path in VMD :)
- path2xyz.py: A python program to convert path.info to path_all.xyz
- extractedmin2pdb.py: A python program to convert exctractedmin to PDB format
- makerestart: A bash script to automatically set up a GMIN restart run
- recommended bash aliases
- David's .vimrc file
- David's .inputrc file
Useful linux stuff
- basic linux commands everyone should know!
- piping and redirecting output from one command or file to another - how to save yourself hours!
- setting up aliases to quickly log you in to a different machine
- transfering files to and from your workstation -using scp or rsync
- printing files from the command line using 'lpr'
- using 'ssh-keygen' to automatically log you into clusters from your workstation (no more typing in your password!)
- the many uses of 'rm' - getting rid of your files safely
- removing an excessive number of files from a directory - when 'rm' just isn't enough
- short 'sed' examples
- short 'awk' examples
- using tar and bzip2 to compress/uncompress files
- conversion between different data file formats -'almost one-line' scripts
- conversion between different image file formats - the convert command
- submitting jobs, interactively or to a cluster queue system
- running programs in the background - so you can use your shell for other things at the same time
- identifying job on a node -
Group practice
If you add a page under here please prefix the name with Wales or similar to avoid confusion with pages that apply to the whole sector.
