Description of the tags in this list:
* 1 * Administrative tag
* 2 * Administrative tag
* 3 * Administrative tag
* 4 * ID of the restraint list.
* 5 * Number of restraints in list.
* 6 * Number of violated restraints (each model violation is used).
* 7 * Sum of violations in Angstrom.
* 8 * Maximum violation of a restraint without averaging in any way.
* 9 * Rms of violations over all restraints.
* 10 * Average violation over all restraints.
* 11 * Average violation over violated restraints.
This violation is averaged over only those models in which the restraint is violated.
These definitions are from: Doreleijers, et al., J. Mol. Biol. 281, 149-164 (1998).
* 12 * Threshold for reporting violations (in Angstrom) in the last columns of the next table.
* 13 * This tag
Description of the tags in the per residue table below:
* 1 * Chain identifier (can be absent if none defined)
* 2 * Residue number
* 3 * Residue name
* 4 * Maximum violation in ensemble of models (without any averaging)
* 5 * Model number with the maximum violation
* 6 * Number of models with a violation above cutoff
* 7 * List of models (1 character per model) with a violation above cutoff.
An '*' marks a violation above the cutoff. A '+' indicates the largest
violation above the cutoff and a '-' marks the smallest violation over cutoff.
For models 5, 15, 25,... a ' ' is replaced by a '.'.
For models 10, 20, 30,... a ' ' is replaced by a digit starting at 1.
* 8 * Administrative tag
* 9 * Administrative tag
Description of the tags in the per restraint table below:
* 1 * Restraint ID within restraint list.
First node, FIRST member, first atom's:
* 2 * Chain identifier (can be absent if none defined)
* 3 * Residue number
* 4 * Residue name
* 5 * Name of (pseudo-)atom
First node, SECOND member, first atom's:
* 6 * Chain identifier (can be absent if none defined)
* 7 * Residue number
* 8 * Residue name
* 9 * Name of (pseudo-)atom
FIRST node's:
* 10 * Target distance value (Angstrom)
* 11 * Lower bound distance (Angstrom)
* 12 * Upper bound distance (Angstrom)
* 13 * Average distance in ensemble of models
* 14 * Minimum distance in ensemble of models
* 15 * Maximum distance in ensemble of models
* 16 * Maximum violation (without any averaging)
* 17 * Model number with the maximum violation
* 18 * Number of models with a violation above cutoff
* 19 * List of models with a violation above cutoff. See description above.
