SEE ALSO

TR [Tape Read]

USAGE

.OPERATION: TW

.DISK FILE: PIC001
[Enter the name of the disk file that is to be copied onto tape.]

.TAPE FILE NUMBER: 2
[Enter where on the tape the disk file is to be copied.]

.ENTER OPTIONS: (F)SCAN, (L)ABEL, (C)ONTUR: FLC
[Enter options in any order. The three options are independent of each other, and correspond to the folowing]:

'F'--Use flip scan rather than normal raster scan.

'L'--Write label underneath the picture

'D'--Contouring using data clipping.

[If the Contour option is chosen, SPIDER asks]:

.NUMBER OF CONTOUR LEVELS: 4
[Enter the number of density fold-over levels.]

[The program now gives the final picture dimensions. Please write these down, as they may be useful for arranging the output pictures of the negative in the film writing step.]

FINAL PICTURE DIMENSIONS: 132,166

.DISK FILE: *
[If no more pictures are to be copied, enter a '*'.]

[PIC001 is then copied as the second file on the tape.]

NOTES

  1. The tape must have a write ring on it (see User's Introduction, section 4.1).

  2. Mount tape as "foreign": $ MOU/FOR MTA0 --or-- $ MOU/FOR MTA1 (VAX 11/780) $ MOU/FOR MSA0 (VAX 11/750)

  3. Under DO-loop control in batch mode (see 'DO'), SPIDER will not continue soliciting the file name until a '*' is entered. Instead, SPIDER goes back into operation input status.
