It is in principle possible to configure TOPCAT to work with table file formats other than the ones listed in this section. It does not require any upgrade of TOPCAT itself, but you have to write or otherwise acquire an input and/or output handler for the table format in question.
The steps that you need to take are:
startable.readers
and/or
startable.writers
system property to the name of the
handler classes (see Section 10.2.3)Explaining how to write such handlers is beyond the scope of this document - see the user document and javadocs for STIL.
