Description
Process a CHARMM trajectory file with custom commands and custom functions. This function provides similar function to analyzeCHARMM.pl but does not require CHARMM and offers greater flexibility, especially for non-standard systems.
Options
- -help
- usage information
- -inx from:to
- analyze the specified frame range from trajectory file
- -step size
- skip the specified number of steps in between frame analyses
- -multi from:to
- read from multiple DCD files (file name given as template) with indices according to given range of numbers
- -apply cmd
- each frame will be temporarily converted into a PDB file and analyzed according to the given command
- -function file
- analyze frames with an internal perl function (see analyze.pl for more information
- -extract name
- extract structures and store them as PDB files with a common tag name
- -ensdir dir
- extract structures into an ensemble with the specified directory name
- -ens tag
- extract structures into an ensemble with the specified tag name
- -rms CA|CAB|C|O|N|side|back|all ... ref
- calculate the root mean square deviation of each frame with respect to a reference PDB structure
- -qscore ref
- calculate Q-score for each frame
- -boxsize
- extract box size information from trajectory
- -average
- calculate average structure from trajectory
- -fit ref
- fit each frame to the reference
- -fitsel cab|ca|cb|heavy
- fit each frame with respect to the specified atom selection
- -psf file
- use specified protein structure file (PSF)
- -atoms from:to
- use specified atom selection range
Examples
processDCD.pl -inx 5:10 -apply rgyr.pl 1vii.pdb 1vii.dcd
calculates the radius of gyration for structures from frames 5-10 from this trajectory
