1. Other Xport data analysis and reduction components
Component: Setup
Inputs
Outputs
(From GUI) Scan parameters: start position, axis, increment, # of images,
file name template, HPSS storage location
Header info: Principal User’s name, Run title,
sample name, formula, unit cell, space group, orientation, mosaicity
Gather information about experiment from GUI, build Bruker startup file, exec Bruker data collection program, wait for operator to verify setup and start run.
NT: Java, Servlet, RSH, RMI, or CORBA exec
(To file system)
Bruker startup file
Prototype file header
(To Mover component ?)
HPSS storage location (?)
Template frame file name (?)
Bruker frame directory
Exec Bruker software with startup file
Component: Mover
Monitor Bruker frame mailbox directory and transfer new complete frames to storage server.
NT: Java, Servlet, RSH, RMI or CORBA exec
File name template
Mailbox directory name
Expected number of frames
HPSS server/directory to put frames in
Time-out in seconds to flag error
HPSS I/O shim component port number
Individual frames are sent as files to the HPSS system using unix-like file I/ semantics on the HPSS shim component’s port.
Components that run on the data collection system, e.g. for Bruker, Windows-NT; for EPICS, Unix
Component: HPSS I/O
Inputs (TCP socket and Port)
Outputs (TCP socket and Port)
Provides unix-like file I/O semantics on a TCP port for HPSS file creation, reading, seeking and writing.
