====== User Macros ====== 

The links in the table are to different macros that users have contributed (most are taken from the collection at [[http://www.dur.ac.uk/john.evans/topas_academic/macros.inc]]).  Please feel free to add your own macros.  Follow the format of one of the pages already created (or look at [[how_to_contribute#formatting_macros]]).  Please add enough documentation that others can follow it! Try and keep the table roughly alphabetical.  More detailed instructions are available on [[how to add a macro]].

The page [[all_macros]] contains many macros in a single file.

You can just copy/paste a macro into an INP file OR (not and!) place it in "local.inc" which is in the main topas directory.  Note that you topas will throw an exception if a macro is defined twice.  You can learn the syntax by looking at the predefined macros which are in topas.inc.  There's also a great forum post on this by Matthew Rowles.
