7.6. GAMESS trajectory reader — MDAnalysis.coordinates.GMS
¶
Resources: the GMS output format is a common output format for different GAMESS distributions: US-GAMESS, Firefly (PC-GAMESS) and GAMESS-UK.
Current version was approbated with US-GAMESS & Firefly only.
There appears to be no rigid format definition so it is likely users
will need to tweak the GMSReader
.
- class MDAnalysis.coordinates.GMS.GMSReader(outfilename, **kwargs)[source]¶
Reads from an GAMESS output file
- Data:
- ts
Timestep object containing coordinates of current frame
- Methods:
len(out)
return number of frames in out
for ts in out:
iterate through trajectory
Note
GMSReader
can read both uncompressed (foo.out
) and compressed (foo.out.bz2
orfoo.out.gz
) files; decompression is handled on the flyChanged in version 0.11.0: Frames now 0-based instead of 1-based. Added dt and time_offset keywords (passed to
Timestep
).- property n_atoms¶
number of atoms in a frame
- property runtyp¶
RUNTYP property of the GAMESS run
- units = {'length': 'Angstrom', 'time': 'ps'}¶
dict with units of of time and length (and velocity, force, … for formats that support it)
