Generic SSV FormatΒΆ

The Generic Space-Seperated Value(SSV) Format allows you to import and use arbitrary attributes.

An .ssv file must start with a line defining available attributes in the file. The next line must contain the total number of atoms. There can be an arbitrary number of spaces between values, but there should be no blank lines between each entry.

Example:

#type resnm name posx posy posz attr=foo
3
H HOH H1W 0.5 1.0 0.0 0.2
H HOH H2W 0.0 1.0 0.0 0.5
O HOH OW  0.0 1.0 1.0 1.0

Available definitions are as follows:

Name Description Format
id atom id integer
type atom type char
name atom name string
resid residue id integer
resnm residue name string
posx x coordinate double
posy y coordinate double
posz z coordinate double
velx x velocity double
vely y velocity double
velz z velocity double
attr=[name] attribute double
ignore none any

The attr entry imports the array as an attribute. Special attributes that are automatically assigned if used are as follows:

Name Description
rotx, roty, rotz Orientation axes

Attributes can be ignored with the ignore entry. Additionally, extra attributes behind defined ones will be ignored.

Example:

#name ignore posx posy posz
1
ATOM asdf 0.0 1.0 0.0 asdf asdf

In this case, asdf entries are ignored.
