Setting the software environment

Before you run any OSA software, you must also set your software environment correctly. If not already set by default by your system administrator, you should set some environment variables, typing

setenv ISDC_ENV directory_of_OSA_sw_installation
setenv ISDC_REF_CAT "$REP_BASE_PROD/cat/hec/gnrl_refr_cat_0040.fits[1]"
source $ISDC_ENV/bin/isdc_init_env.csh

in order to:

• set ISDC_ENV to the location where OSA is installed,
• set ISDC_REF_CAT to the DOL of the ISDC Reference Catalog
• run the OSA set-up script (isdc_init_env.csh) which initializes further environment variables relative to ISDC_ENV.

The SPI pipeline creates a log file with all relevant information automatically each time it is executed. If you, however, want to log not only the output from the pipeline, but also from all your other OSA activities, set the environment COMMONLOGFILE as follows:

setenv COMMONLOGFILE +name.log

where name.log is the name of the log file. You can use any name you want, but do not forget the + in front, otherwise, no information will be written to the screen any more.

As your level of expertise with the software increases, you may wish not to have the Graphical User Interface (GUI) pop up when you launch your analysis. In this case, the variable COMMONSCRIPT must be defined:

setenv COMMONSCRIPT 1

To revert to having the GUI, unset the variable:

unsetenv COMMONSCRIPT
