This project contains a list of scripts intended to automate various aspects of structure analysis. They are usually called from the command line and accept input from STDIN. A more detailed description of each program is given here 1) anomalous_around.py This program contacts the Periodic Table interface to X-ray absorption edges at the Biomolecular Structure Centre at University of Washington and obtains the F' and F'' values for a particular element around a particular wavelength in Å or an Energy in electron Volt (ev) for eg. $ python anomalous_around.py -a Se -w 1.001 Indexed values for Value:12386.0323843, 12300.00 ('-3.071344', '0.5298917') 12400.00 ('-3.383753', '0.5221294') 12500.00 ('-3.863509', '0.5145381') Documentation: Usage: anomalous_around.py [options] Options: -h, --help show this help message and exit -a Se, --atom=Se Atom id for eg. Se -e [Energy ev], --energy=[Energy ev] Energy in ev -w [wavelength], --wave=[wavelength] Wavelength in A 2) clustal_align_to_pdbfig.py This program uses a typical pairwise clustal alignment and converts the "*" , ":" , "." and " " line in the alignment to a numeric value and then replaces the B-factor record in the db file with 100,50,25 or 0 for a fully conserved(*) , Similar(:) , nearly similar (.) or non-conserved residue Usage: clustal_align_to_pdbfig.py [options] Options: -h, --help show this help message and exit -i *.pdb, --infile=*.pdb -a *.txt with alignment, --alignment=*.txt with alignment Sample input for this can be a screen copy paste of the alignment or the alignment file itself from a website like the Expasy clustaw site at http://www.ebi.ac.uk/Tools/clustalw2/index.html 3)compile_rsmd_to_bfac_column.py This program transfers the rms-distance between two aligned pdbs as output by coot to the B-factor column on all of the chains in the pdb [smarter version in the works] Usage: compile_rsmd_to_bfac_column.py [options] Options: -h, --help show this help message and exit -i *.pdb, --infile=*.pdb input file to append bfactors to -s *.txt, --screedump=*.txt input file with screen dump after SSM superpose coercing to Unicode: need string or buffer, NoneType found
