GROUPS

GROUPS:

Groups as of D3PLOT 9.0 (Nov 2003) have been extensively rewritten to remove some limitations and to provide new features. In particular:

• You may now have an unlimited number of groups. The previous limit of 30 is removed.

• Groups are now automatically stored in a " .grp " file for this model, and are "remembered" across successive runs of D3PLOT, with no intervention required by the user. " .grp " files are model dependent binary files.

• The ascii *GROUP format used by PRIMER may be read in as " .asc " files, and converted to internal groups. These files may be created simply by hand, and are model independent. " .asc " files may also be written. They are also read by T/HIS, and this permits groups to be used consistently across the software suite.

Groups may be used in most contexts where selection takes place, for example BLANK , WRITE , etc.

They can be set up for a model in any of the following ways:  

• Defined interactively during a D3PLOT run using CREATE .
• Read in from an external ascii ( .asc ) groups file
• Read in from an "old" binary ( .bin ) groups file
• Reread from a previous D3PLOT run, made available automatically via the < jobname > .grp file.

For backwards compatibility the "old style" binary groups files " .bin " may still be read (see READ_OLD... Reading "old" (pre version 9.0) binary .bin groups files ), but they are no longer written and their use is deprecated.
