Set-Up

The current delivered version of the code is in the following directory tree : 


Directory DISK$GSC2:[PIPELINE]

AXPEXE.DIR	: AXP versions of executables   
CLD.DIR         : CLD files for defining additional DCL tasks
COM.DIR         : COM files for defining symbols
LOG.DIR         : LOG files for plate processing
SETUP.COM       : COM file to define logicals/symbols for environment
VAXEXE.DIR      : VAX versions of executables
Run the SETUP.COM file and you will define all necessary logicals and symbols to run the pipeline tasks

Environment

The images are processed on HAVEN using the two scan disks. We process 3 at a time (even though there are 6 scan slots) on each of 2 disks with directories for pipeline processing as follows : 

Directory DISK$SCANDATA1:[CASB]

COMPRESSED.DIR     : Compressed images are saved here (subdir per plate)
PRDD1.DIR          : Scan slot DD1
PRDD2.DIR          : Scan slot DD2
PRDD3.DIR          : Scan slot DD3
PRDD4.DIR          : Spare slot DD4
PRDD5.DIR          : Spare slot DD5
PRDD6.DIR          : Spare slot DD6
PROCESSED.DIR      : Pipeline files are saved here (subdir per plate)
RUN_PIPELINE_1.COM : Command file to process all images on this disk
SCRATCH            : Scratch space

Directory DISK$SCANDATA2:[CASB]

COMPRESSED.DIR     : Compressed images are saved here (subdir per plate)
PRDDA.DIR          : Scan slot DDA
PRDDB.DIR          : Scan slot DDB
PRDDC.DIR          : Scan slot DDC
PRDDD.DIR          : Spare slot DDD
PRDDE.DIR          : Spare slot DDE
PRDDF.DIR          : Spare slot DDF
PROCESSED.DIR      : Pipeline files are saved here (subdir per plate)
RUN_PIPELINE_2.COM : Command file to process all images on this disk
SCRATCH            : Scratch space
After the scans on each disk have been archived to SONY WORM as part of the CASB image archive (and if necessary archived to data grade 8mm) they are processed sequentially using the associated command file. As each is processed, the compressed tiles are moved to the COMPRESSED tree and the pipeline files moved to the PROCESSED tree so that the scan slot is emptied on completion. After 2 cycles on each disk there are data for 6 plates in both the COMPRESSED and PROCESSED trees.

After we have 6 plates in the COMPRESSED directory of either scan disk, these data are (currently) moved to an MFIVE local disk for premastering. These 6 scans are all archived to the same SONY platter, the compressed data to the same CD-R and the pipeline files to the same 8mm backup tape.
