CLEAR ATOM * * CA will include all C alphas in the list. ALL ENTER CLEAR ATOM * * H* EXCL will include all non-hydrogen atoms. CLEAR RANGE BYNU 1 100 will include atoms number 1 to 100.
CLEAR RANGE MAIN 1 CA MAIN 10 CA ENTER - CLEAR ATOM * * H ATOM * * N ATOM * * O EXCL will include all the atoms from CA of reside 1 to CA of residue 10 in the segment MAIN except atoms H, N, and O.
CLEAR BYNU 1 3 5 7 9 11 13 15 ATOM SOLV * * will include atoms number 1, 3, 5, 7, 8, 11, 13, and 15, and the SOLV segment.
CLEAR ATOM S1 10 * AROUND 8.0 ENTER - CLEAR ATOM S2 * * ATOM S3 * * AND BYRES selects all atoms which are in residues which have atoms in segments S2 and S3 that are within 8.0 A of residue 10 in segment S1.
CLEAR COOR X GE 0 ENTER - CLEAR COOR Y GE 0 AND ENTER - CLEAR COOR Z GE 0 AND ENTER - CLEAR COOR X LE 5 AND ENTER - CLEAR COOR Y LE 6 AND ENTER - CLEAR COOR Z LE 7 AND selects those atoms within a rectangular box between the origin and (5,6,7)
All of the atom selections are interpreted using the
SELCTA routine in SELCTA.FLX. Wildcard interpretation is
handled by the
EQSTWC routine in STRING.FLX.
