- .OPERATION: PT
- .OUTPUT FILE: H_IMG042
[Enter the name of an existing or new pattern file.]
- If the pattern file does not exist, SPIDER will ask:
- .ENTER DIMENSIONS (NSAM, NROW): 32,64
[Enter the sample and row sizes of the pattern file.]
.ENTER PATTERN CODE (P,L,C,T,R,S): P
[Enter the pattern code desired (see below for listing
of all possible codes.]
- For (P)oint ('P' or 'PS') , SPIDER will ask:
- .ENTER COORDINATES: 12,15
[Enter the coordinates of the point.]
[The specified image point will be set to 1.0
(code: 'P') or to 0.0 (code 'PS'), respectively.]
- For (L)ine ('L' or 'LS') , SPIDER will ask:
- .ENTER COORDINATES OF STARTING POINT: 12,17
.ENTER COORDINATES OF ENDING POINT: 23,32
[Enter the coordinates of the two end points of the line.]
[All points along the line between the two specified
margin points (i.e. the nearest grid point in every
column and row) will be set to 1.0 (code: 'L') or to 0.0
(code: LS), respectively.]
- For (C)ircle ('C', 'CS', 'CL', or 'CLS' ) , SPIDER will ask:
- .ENTER CENTER COORDINATES: 12,15
.ENTER RADIUS: 8.
[Enter center coordinates and radius of the circle.]
[Either, all points within the area limited by circle
with the specified center and radius are set to 1.0
(code: 'C') or 0.0 (code: 'CS'), respectively, or, only
those image points belonging to the margin of the
specified circle (i.e. the points lying on the margin line of
the circle) are set to 1.0 (code: 'CL') or to 0.0 (code:
'CLS'), respectively.]
- For (T)riangle ('T', 'TS', 'TL', or 'TLS' ) , SPIDER will ask:
- .ENTER COORDINATES OF FIRST POINT: 12,16
.ENTER COORDINATES OF SECOND POINT: 22,10
.ENTER COORDINATES OF THIRD POINT: 3,5
[Enter the coordinates of the three apexes of the triangle.]
[Either, all points within the area limited by the
triangle with the specified margin points are set to
1.0 (code: T) or 0.0 (code: 'TS'), respectively, or,
only those image points belonging to the margin lines
of the specified triangle are set to 1.0 (code: 'TL') or
to 0.0 (code: 'TLS'), respectively.]
- For (R)ectangle ('R', 'RS', 'RL', or 'RLS' ) , SPIDER will ask:
- .ENTER COORDINATES OF UPPER LEFT POINT: 10,8
[Enter the coordinates of the upper left corner of the
rectangle.]
.ENTER X AND Y OFFSETS: 2,4
[Enter the X and Y offsets to the lower right corner.]
[Either, all points within the area limited by the
specified rectangle are set to 1.0 (code: 'R') or 0.0
(code: 'RS'), respectively, or, only those image points
belonging to the margin lines of the specified
rectangle are set to 1.0 (code: 'RL') or to 0.0 (code: 'RLS'),
respectively.]
- For all selections SPIDER will ask:
- .CONTINUE ? (Y,N): Y
[Enter 'Y' if you want to "add" or "subtract" another
elementary pattern, enter 'N' if you are finished.]
