NMRWish Built-In TCL Functions
dynSelect: Select atoms according to the specified conditions, such as by residue name, etc.

Flag	Argument	Default	Description
`-src`	`pdbSrc`		Source of Structure.
`-append`			Append to previous selection.

Dynamics Selection:

`-fixed`			Set Selected Atoms as Fixed.
`-nofixed`			Set Selected Atoms as Fixed.

Output and Result Options:

`-verb`			Verbose Mode ON.
`-list`			Return Atom Entry List.
`-nolist`			Return Select Count (Default).
`-res`	`resID`		Single Residue for Selection.
`-r1`	`res1`		First Residue in Segment.
`-rN`	`resN`		Last Residue in Segment.
`-e1`	`ae1`		First Atom Entry in Segment.
`-eN`	`aeN`		Last Atom Entry in Segment.
`-atomName`	`aList`		Atom Name List (also -atom).
`-resName`	`rList`	`*`	Res Name List.
`-chain`	`cList`	`*`	Chain Name List.
`-seg`	`sList`	`*`	Seg Name List.
`-id`	`sID`		Selection ID.
`-inv`			Invert Selection.

Special Class Selection:

-protein Select Only Canonical Amino Acids.

Selection Within Coord Sphere:

`-near`	`rad`	Selection Radius (Angstroms).
`-x`	`x0`	Center X Coord (Angstroms).
`-y`	`y0`	Center Y Coord (Angstroms).
`-z`	`z0`	Center Z Coord (Angstroms).

Selection Within Coord Region (Also -y... -z...):

`-x1`	`x1`		Region X1 Limit (Angstroms).
`-xn`	`xn`		Region XN Limit (Angstroms).

Reset Selection. No Other Selection Performed:

`-clear`			Clear Selection for All Atoms.
`-set`			Set Selection for All Atoms.

Name Matching Modes:

`-exact`			Match Names Exactly (Default).
`-regex`			Regular Expression Pattern Matching.
`-glob`			Glob-style Pattern Matching, and with # for numerals in atom names.

PDB Input Options:

-hetatm Interpret HETATM records as ATOMs.

Notes (New Version of dynSelect):
1. Use -append to retain previous selection.
2. Use -atom * to select all atom names.
2. Use -res * to select all residues.
