Widget:

• Select "Transform File" from the "File" menu. A file selection widget will appear. When you have made your selection, the specified transform file will be read.

• TRANSFORM_FILE=FILE_NAME

• FILE_NAME: The full or relative path name of any compiled IVE transform file

• TRANSFORM_FILE = ~/trans/trans_model

• If the coordinate surfaces of your data are curved, you must first supply IVE with a TRANSFORM FILE. Transforms map your curvilinear coordinates to a rectangular Cartesian grid.
• The transform file name can also be specified using the environment variable IVETRANSFILE (see Environment Variables).
• The IVETRANS environment variable can be used to specify a directory for the widget to search in (see Environment Variables).
• Refer to Writing Transforms for IVE for information on writing your own transform routines.
