Syntax
ANGLedb {<bond-angle-database-statement>} END ANGDB-statement>:== ASSIgn <sel> <sel> <sel> <sel> <sel> <sel> <sel> <sel> <sel> <sel> <sel> [<sel>] ! add an entry to the current class. Selections define ! the dihedral angle(s) for that entry. CLASsification <name> ! Starts a new class. Applies to all ASSIgn, EXPE, ! FORCe, and SIZE entries until another CLASs entry ! is issued. DERIVflag < ON | OFF> ! Turns derivatives with respect to ! phi and psi on and off. EXPEctation <integer> <integer> <real> ! Indicates coordinates in the expectation grid ! and the value at those coordinates. ERROr <real> ! Set the square well error for the current ! class (in EXPE units). FORCeconstant <real> ! force constant for all assignments ! in the current class. (default : 1) NREStraints <integer> ! number of slots for angle database ! restraints to allocate in memory. (default :200) POTEntial <SQUAre | HARMonic> ! use errors or not. PRINt THREshold <real> <ALL | CLASs <name>> ! prints ! angle database violations greater than the specified value ! for all classes or just for the named class. RESEt ! erases the angle database assignment table. SIZE <ANGLe | DIHEdral> <integer> <integer> ! Defines the ! type of the third angle in the current class expectation ! grid and the number of steps along each dimension. ZERO ! zero out all the expectation value arrays.
