Parameters

first=atom selection
(required)
second=atom selection
(required)
levels=integer range
(default: -99999..99999)
distance=real range
(default: 0.0..99999.9)

Description

This command lists interatomic distances between atoms selected by the 'first' and 'second' atom selection. Only those atom pairs with a residue number difference in the given range of levels are considered. If structures have been read and selected, then only those atom pairs with a corresponding average distance in the given distance range are considered.
The command reports the average distance, its standard deviation, minimal value and maximal value in the selected structures, as well as the number of structures in which the distance lies in the given distance range. For each selected structure, the distance value is represented schematically by a '-' sign if the distance is shorter than the lower bound of the distance range, by a '*' sign if it is within the bounds of the 'distance' range, or by a '+' sign if it is longer than the upper bound of the distance range.
