PyMOLCalculateRMSD.py -h | --help | -e | --examples
Calculate Root Mean Square Distance (RMSD) between a set of similar macromolecules in reference and probe input files. The probe and reference files are spatially aligned before the the calculation of RMSD values.
The supported input file format are: PDB (.pdb), mmCIF (.cif)
The supported output file formats are: CSV (.csv), TSV (.tsv, .txt)
Alignment methodology to use for aligning probe input files to reference files.
Portion of probe and reference files to use for spatial alignment of probe files against reference files. Possible values: FirstChain or Complex.
The FirstChain mode allows alignment of the first chain in probe files to the first chain in reference files along with moving the rest of the complex to coordinate space of the reference files. The complete complex in probe files is aligned to the complete complex in reference files for the Complex mode.
Print this help message.
Specify how reference and probe input files are handled during the calculation of RMSD between reference and probe files. Possible values: OneToOne, AllToAll and AllToFirst. For OneToOne mode, the number of reference input files must be equal to the number of probe input files. The RMSD is calculated for each pair of reference and probe file and written to the output file. For AllToAll mode, the RMSD is calculated for each reference input file against all probe input files. For FirstToAll mode, however, the RMSD is only calculated for the first reference input file against all probe files.
A comma delimited list of probe input files. The wildcards are also allowed in file names.
A comma delimited list of reference input files. The wildcards are also allowed in file names.
Output file name for writing out RMSD values. Supported text file extensions: csv, tsv or txt.
Output file in a matrix format during 'AllToAll' value for '-m, --mode' option.
Overwrite existing files.
Location of working directory which defaults to the current directory.
