7.5 ISIS Coexistence

ISIS Setup Script

After running the scripts vicset1.csh and vicset2.csh, run the Script to Setup ISIS for Users Then you may start ISIS by typing: % isis.

Other Steps Necessary for ISIS/VICAR Coexistance

• The Script to Setup ISIS for Users assumes the preferred configuration in the ISIS Installation Manual Step 5: the entire ISIS system exists under a single top-level directory.
• If the ISIS data files are installed in a directory other than the default setup described in the ISIS Installation Manual, step 5, then the path containing the data files must be set prior to running the Script to Setup ISIS for Users (See ISIS Installation Manual, step 5.)
• A single statement in the IDL program isislib.pro, located in $ISISEXE must be modified to reflect the absolute path of the image isis2idl.so which is also located in $ISISEXE. See ISIS Installation Manual, step 7, last two paragraphs.
• The standard IDL setup creates an alias for idl instead of putting it in the path. This messes up the "xterm -e" that's in the isis alias. You can get around this by putting idl directly in the path, or providing xterm -e with the complete pathname to idl, instead of using the alias.
• ISISR is a standard ISIS environmental variable that points to the top of the ISIS executable directory, /usgs/isisr for example. If only ISISR needs to be set, it can be set manually before running the Script to Setup ISIS for Users or the Script to Setup ISIS for Users can be changed to match. Any of the other ISIS Installation Manual, step 5 env vars could be set up in the Script to Setup ISIS for Users as well.
• LD_LIBRARY_PATH environmental variable as described in ISIS Installation Manual, step 5 does not need to be set because the Script to Setup ISIS for Users does it.
• The script references IDL_STARTUP in isisr; in other words, we put that file in the isisr top level. If they want to have it elsewhere, change the Script to Setup ISIS for Users (step 7 in ISIS Installation Manual).
• An individual program can be run from either the VICAR or ISIS libraries by prefixing the name. See below:
• If there is an ISIS version of a program with the same name as a VCAR program, the VICAR program will be used. To change this behavior so that the ISIS program is chosen per session use the TAE command:
  SETLIB ($ISISEXE, $PICEXE,*)
  To persist across sessions, put this line in the slogon.pdf
