Loop File

Name

Any name is fine as long as you specify the correct file name in the command lines. For Example:

*.loops 

Purpose

Loop definitions are used to identify the residues in a loop. See: The -loops, the -loop_file, and many others.

Format

column1  "LOOP":     Literally the string LOOP, identifying this line as a loop
                     In the future loop specification files may take other data.
column2  "integer":  Loop start residue number
column3  "integer":  Loop end residue number
column4  "integer":  Cut point residue number, >=startRes, <=endRes. Default or 0: let LoopRebuild choose cutpoint randomly.
column5  "float":    Skip rate. default - never skip
column6  "boolean":  Extend loop. Default false

Example

For Example: A legal line in a loops file (the line by itself is a legal file):

LOOP 23 30 26
Loop from residues 23-30 with the cutpoint at 26.
