To run the Interactive Double Mass Analysis tool, the following items are
required:
Historical Data Database
This database contains information about the historical data stored in
HRL archives. It is the same database used by the Historical Data Browser.
runidma script
The IDMA tool is started by executing the command "runidma" which is a
Unix script. The runidma script contains a number of statements which can
be tailored for each individual user by editing the runidma file. They are:
export IDMA_DIRECTORY=pathname
- where pathname is the path to the directory tree containing the IDMA
software.
export HTML_HELP_DIRECTORY=pathname
- (Do NOT Change) tells where to find the user's guide on the HRL web site.
export BROWSER=browser
- set to the web browser that will be used for displaying help. If you
have no browser installed on your system at this time, leave the value
blank.
export IDMA_DEBUG_ROUTINE=boolean
- set to TRUE to dump which routine were called for debugging to a log file
otherwise set to FALSE.
export IDMA_DEBUG_SQL=boolean
- set to TRUE to dump queries to database and results for debugging to a log file
otherwise set to FALSE.
export IDMA_DEBUG_STATION_INFO=boolean
- set to TRUE to dump information about stations and contents for debugging to a log file
otherwise set to FALSE.
export IDMA_DEBUG_USER_ACTION=boolean
- set to TRUE to dump what the user has done for debugging to a log file
otherwise set to FALSE.
Note: you may need to set the enviorment variable TEMPDIR to avoid problems
with running MAP, MAT and MAPE. See the scratch file section of calbration system programs
.Apps_defaults File
The .Apps_defaults file contains parameters that are shared
by the preprocessors and the Historical Data Browser. Please
refer to the appropriate documentation for definition of these parameters.
