TXYZ, ARC (Tinker)

Coordinate reader	MDAnalysis.coordinates.TXYZ.TXYZReader
Topology parser	MDAnalysis.topology.TXYZParser.TXYZParser

MDAnalysis can read Tinker xyz files .txyz and trajectory .arc files.

Developer notes

Differences between Tinker format and normal xyz files:

• there is only one header line containing both the number of atoms and a comment

• column 1 contains atom numbers (starting from 1)

• column 6 contains atoms types

• the following columns indicate connectivity (atoms to which that particular atom is bonded, according to numbering in column 1)
